Stainless Steel Level Sensor-Pressure Guided Submersible Level Transmitter (gas pressure type. ) The sensor part and the signal processing circuit are inside the junction box. It is used for high temperature, corrosive liquid, sewage, etc. The gas in the gas collecting cylinder is injected into the liquid Contact with the medium. The pressure is transmitted to the sensor through the air pipe. The direct contact between the sensor and the measured medium is avoided. It is suitable for occasions such as high temperature and strong corrosiveness. It effectively solves the problem of high temperature corrosive liquid and sewage level measurement. It is especially suitable for the measurement of high temperature, corrosive liquid and sewage.
Stainless Steel Level Sensor-Pressure Guided Submersible Level Transmitter Working Principle
The Pressure Guided Submersible Level Transmitter selects the pressure transmitter as the pressure measurement component. The liquid level pressure signal is collected by the gas collecting cylinder and transmitted to the pressure transmitter to convert the pressure signal into the liquid level signal output.
The relationship between pressure transmitter and liquid level is: P=0.0098ρH+Pc
where: P pressure MPa; ρ liquid density (g/cm3); H liquid level depth (m); Pc liquid surface pressure (normal pressure is 0)
Stainless Steel Level Sensor-Pressure Guided Submersible Level Transmitter is a good choice for diesel testing. Its biggest advantage is simple installation and low cost. Professional commissioning and installation, setup, etc. are not required. Just put the stainless steel probe into the tank and the solid gauge head.
In the petrochemical industry, large oil tanks require a large range of high-precision liquid level sensors to monitor oil level. At present, there are many methods for measuring oil tank liquid levels:
One of the more important factors to consider when choosing a submersible level meter in the wastewater treatment industry is chemical compatibility and material selection. From potable water to highly corrosive acids, submersible level Meters are necessary to measure nearly countless liquid chemicals.
Long service life; High-precision measurement is possible from water, oil to viscous paste; A wide range of temperature compensation is not affected by the foaming, deposition, and electrical properties of the measured medium.
If you want to measure the liquid level of high temperature media, in addition to the available magnetic flap, the economical choice is the submersible high temperature Stainless Steel Level Sensor.
Since the medium is high temperature, the measurement method should avoid direct contact between the probe sensor and the medium. The probe sensor can only withstand a temperature of 60 degrees. For this reason, the submersible high temperature Stainless Steel Level Sensor is structurally designed to have the probe sensor above the medium and not in contact with the medium at all. . So no matter how high the medium temperature is, the submersible high temperature Stainless Steel Level Sensor can be used freely.
When installing, just find a hole larger than Φ37mm in the liquid level tank and put it directly. The submersible high temperature Stainless Steel Level Sensor is also equipped with a display for ease of use. Reasonable prices will make every customer satisfied.
More than just liquid level, monitor your tank volume more effectively!
Our liquid level sensors can output liquid level signals, such as 4-20mA signal, 0-10V signal, RS485 and so on.
However, the liquid level transmitter alone cannot calculate the liquid volume of tanks of different sizes. It’s too complicated. A separate recorder is required to calculate it.
Therefore, the digital display volume meter can collect, display and convert the liquid level of various regular and irregular tanks in the industrial field into the corresponding tank volume. It is suitable for monitoring, controlling and collecting various process parameters.

Flow Pressure Transducers are measurements of fluid pressure within a pipeline. When fluid flows through a pipe, pressure acts on the pipe wall. The medium in the pipeline can be liquid or gas. Measure the pressure of the fluid, on the one hand, you can understand the pressure in the pipeline. On the other hand, pipeline flow can be monitored through the relationship between pipe diameter-pressure-flow.
Differential pressure sensors have been widely used to measure the flow of incompressible liquids. A very common method is to measure the pressure drop across the orifice in the pipe and calculate the flow.
An orifice plate is simply a plate that fits in a pipe (usually between flanges) with a hole of known size in its center. As the fluid flows through the orifice, a pressure drop develops across the orifice plate from the upstream side to the downstream side. This pressure drop is proportional to flow, and the sensor signal can be used to calculate flow in engineering units.
The upstream side of the orifice will have higher pressure and will be connected to the + port of the pressure sensor through a three-valve manifold. The downstream side of the orifice is similarly connected to the -port of the pressure sensor. The three-valve manifold is used to protect the pressure sensor from overpressure when the pressure sensor is installed into the work pipeline.
Calculations to determine flow from pressure drop are derived from fairly simple physical equations. However, there are many variables, each with its own engineering unit. These include: hole geometry, pipe size, fluid viscosity and fluid density. Given the number of terms and the conversion factors involved in each variable, the calculation can be quite involved.
Fortunately, there are many online calculators that allow you to simply enter variables in any engineering units that are convenient for you, and then calculate the flow rate for any given pressure drop across the orifice.
Fluid Pressure Transducers are mainly used in: construction machinery, hydraulic and pneumatic systems, petrochemicals, energy and water treatment, water conservancy and hydropower, compressors and other fields:
How to install the pressure sensor when measuring the flow pipeline?
When detecting the gas and fluid pressure in the pipeline, the pressure guiding pipe is connected with a vertical tee before entering the pressure sensor. The sampling gas enters from the upper part of the tee. The lower part of the tee is connected to a water collecting irrigation, and the horizontal interface of the tee enters the pressure sensor .
The pressure sensor is installed horizontally. The sampling pressure pipe is connected to the upper part of the pressure sensor detection diaphragm. The lower part of the detection diaphragm has its own discharge bolt.
When there is liquid entering the pressure guiding pipe, a large part will be collected in the water collecting irrigation. A small amount of liquid entering the pressure sensor detection diaphragm can be discharged by the discharge bolt of the pressure sensor.
When measuring fluid pressure, the pressure of the main fluid is taken as the measurement object. Therefore, when the pressure sensor measures the gas pressure in the pipeline, in order to prevent the liquid in it from entering the sampling pressure pipe. The sampling point is 45° above the horizontal plane of the center of the pipeline.
When measuring the liquid pressure of the pipeline, in order to prevent the gas in it from entering the sampling pressure guiding tube, the sampling point is 45° below the horizontal plane of the center of the pipeline. Read more about: Shop 101: Key Factors In Selecting A Pipe Flow Meter
Even so, it is inevitable that different phases of fluid will enter the sampling impulse pipe. There are different requirements for the installation and configuration of the pressure sensor impulse pipe.
The water collecting tank or gas collecting tank installed on the pressure guiding pipe is equipped with an inlet valve and a discharge valve. During normal testing, the inlet valve is opened and the discharge valve is closed. When it is necessary to discharge, first close the inlet valve, and then open the discharge valve. . This discharge method will always have a bit of out-of-phase fluid remaining in the water or gas header, but it will not affect the pressure sensor detection accuracy.
Fluids include both gaseous fluids and liquid fluids. The density and pressure of gaseous fluids are lower than that of liquid fluids. So in pipeline fluids, the gaseous fluid is always above the liquid fluid. This is the basic characteristic of vapor-liquid two-phase fluid.
There are many types of pressure sensors. Such as resistance strain gauge pressure sensors, semiconductor strain gauge pressure sensors, piezoresistive pressure sensors, inductive pressure sensors, capacitive pressure sensors, resonant pressure sensors, etc.
Flow is an important parameter in industrial production and life. The amount of fluid flowing through a section of a pipe per unit time is called instantaneous flow. Instantaneous flow is divided into volume flow and mass flow. A flow sensor is a sensor that measures the flow of a fluid. Flow sensor is an important instrument in measurement technology, it is widely used in industrial process control, life science and technology, commercial application, military and other fields. In recent years, with the development of science and technology and the development of human needs, flow sensors are also constantly developing.

The system has powerful monitoring functions, data calculation and analysis and diagnosis capabilities. It can realize mutual communication control between various devices.
As shown in the figure, the purpose of measuring the liquid level of low temperature medium is achieved by measuring the gas pressure in the pressure guiding pipe.
Because the liquid in the high-pressure side pressure guiding pipe is in a normal temperature state above the boiling point.
Therefore, the liquid in the pressure guiding tube evaporates into gas until saturated gas is formed in the pressure guiding tube.
The differential pressure transmitter should be installed above the maximum liquid level. The high pressure side is connected to the liquid phase pressure guiding pipe. Not only can the transmitter be in a working environment at room temperature, but also the low-temperature liquid can be fully vaporized.
In order to easily adjust the zero position of the instrument and replace the instrument, a balance valve should be installed between the high and low pressure sides of the differential pressure transmitter.
After the differential pressure transmitter is installed, the zero position should be adjusted, then the gas phase pressure pilot valve PL should be opened, and the zero position should be adjusted again under the working pressure.
Then open the liquid phase pressure pilot valve PH. Wait for a while for the cryogenic liquid to fully vaporize. Then close the balance valve to put the transmitter into operation.
When checking or adjusting zero during use, first open the balance valve to balance the pressure on the high and low pressure sides of the differential pressure transmitter, and then close the liquid phase pressure guide valve to check or adjust the zero position.
If the vaporized gas of the liquid to be tested is dangerous in contact with the air, certain safety measures should be taken during maintenance.
Principle: The principle of the connector. Developed according to the principle of buoyancy and magnetic coupling.
When the liquid level in the container under test rises and falls. The permanent magnet steel in the float is transmitted to the magnetic flip column indicating panel through magnetic coupling. Flip the red and white columns over 180°.
The column turns from white to red when the liquid level rises. The column turns from red to white when the liquid level drops.
The junction of red and white on the panel is the actual height of the liquid level in the container, so as to realize the liquid level display.
The structure of the float level meter is mainly designed and produced based on the principles of buoyancy and static magnetic field.
The position of the float with a magnet (abbreviated as float) in the measured medium is affected by buoyancy: changes in the liquid level lead to changes in the position of the magnetic float.
The magnet and sensor (reed switch) in the floating ball act to change the number of components (such as fixed-value resistors) connected in series to the circuit, thereby changing the electrical quantity of the instrument circuit system.
That is, the change of the position of the magnetic float causes the change of the electrical quantity.
The liquid level in the container is reflected by detecting the change of the electrical quantity.
It is designed and manufactured using the principle of mechanical balance.
When the liquid level changes, the original mechanical balance will reach a new balance through the movement of the steel belt under the disturbance of the buoyancy of the float.
The liquid level detection device (float) drives the steel belt to move according to the liquid level. The displacement transmission system drives the transmission pin to rotate through the movement of the steel belt. It then acts on the counter to display the liquid level.
The radar level meter is a measuring instrument based on the principle of time travel. The radar wave runs at the speed of light, and the running time can be converted into a level signal by electronic components.
The probe emits high-frequency pulses and propagates along the cable probe. When the pulses meet the surface of the material, they are reflected back and received by the receiver in the instrument. The distance signal is converted into a level signal.
When the sensor of the magnetostrictive level transmitter works, the circuit part of the sensor will excite a pulse current on the waveguide wire. When the current propagates along the waveguide wire, a pulse current magnetic field will be generated around the waveguide wire.
There is a float outside the sensor rod of the magnetostrictive liquid level gauge. This float can move up and down along the rod with the change of the liquid level.
Inside the float there is a set of permanent magnetic rings.
When the magnetic field of the pulse current meets the magnetic field of the magnetic ring generated by the float, the magnetic field around the float changes so that the waveguide wire made of magnetostrictive material generates a torsional wave pulse at the position of the float. The waveguide wire is returned and detected by the detection mechanism.
By measuring the time difference between the pulse current and the torsional wave, the position of the float, that is, the position of the liquid surface, can be accurately determined.
The radio frequency admittance level meter is composed of a sensor and a control instrument. The sensor can be installed on the roof of the warehouse using rod-type, coaxial or cable-type probes.
The pulse card in the sensor can convert the material level change into a pulse signal and send it to the control instrument. After the control instrument is processed and converted into engineering quantity and displayed, it realizes the continuous measurement of the material level.
The working principle of the tuning fork level controller is to make the tuning fork vibrate at a certain resonance frequency through a pair of piezoelectric crystals installed on the tuning fork base.
When the tuning fork is in contact with the measured medium, the frequency and amplitude of the tuning fork will change. These changes are detected, processed and converted into a switching signal by an intelligent circuit.
The glass plate type liquid level meter is connected to the container through the flange to form a communication device, and the height of the liquid level in the container can be directly read through the glass plate.
The pressure level transmitter adopts the principle of static pressure measurement.
When the liquid level transmitter is put into a certain depth in the measured liquid.
At the same time as the pressure on the liquid surface of the sensor, the pressure of the liquid is introduced into the positive pressure chamber of the sensor through the air-conducting stainless steel. Then the atmospheric pressure Po on the liquid surface is connected to the negative pressure chamber of the sensor to offset the Po on the back of the sensor.
The pressure measured by the sensor is: ρ .g.H , and the liquid level depth can be obtained by measuring the pressure P .
Capacitive level meters measure the level of liquid level by measuring changes in capacitance.
It is a metal rod inserted into the liquid container. The metal rod is used as one pole of the capacitor. The wall of the container is used as the other pole of the capacitor.
The medium between the two electrodes is the liquid and the gas above it.
Because the dielectric constant ε1 of the liquid and the dielectric constant ε2 on the liquid surface are different. For example: ε1>ε2.
Then when the liquid level rises, the total dielectric constant value between the two electrodes of the capacitive liquid level gauge increases accordingly and the capacitance increases.
Conversely, when the liquid level drops, the value of ε decreases, and the capacitance also decreases.
Therefore, the capacitive liquid level meter can measure the level of the liquid level through the change of the capacitance between the two electrodes.
The intelligent electric displacer liquid level meter is a liquid level measuring instrument designed according to Archimedes’ law and the principle of magnetic coupling. The instrument can be used to measure the liquid level, boundary level and density, and is responsible for the output of upper and lower limit alarm signals.
It is designed and manufactured using the principle of mechanical balance.
When the liquid level changes, the original mechanical balance will be disturbed by the buoyancy of the float. The new balance will be achieved by the movement of the steel belt (rope).
The liquid level detection device (float) drives the steel belt (rope) to move according to the liquid level. The displacement transmission system drives the on-site indicating device through the movement of the steel belt (rope), and then displays the liquid level on the display device.
The pontoon is submerged in the liquid in the pontoon chamber and is rigidly connected to the torsion tube system. The force on the torsion tube system is the net weight of the pontoon minus the buoyancy on the pontoon. Under the action of this combined force, the torsion tube is twisted by a certain angle.
Changes in the position, density or boundary level of the liquid in the buoyancy chamber cause the buoyancy force of the buoyancy immersed in the liquid to change, so that the twisting angle of the tube also changes.
This change is transmitted to a sensor rigidly connected to the torsion tube. Change the sensor output voltage. Then it is amplified by electronic components and converted into 4-20mA current output.
Displacer level transmitters use microcontrollers and associated electronics to measure process variables. Provides current output. Drive LCD display and provide HART communication capability.
The magnetic-sensitive electronic two-color liquid level meter is made of high-quality stainless steel and imported electronic components.
The display part adopts high-brightness LED two-color light-emitting tube to form a columnar display screen.
Through the red and green changes of the LED light column, the upper and lower limit alarm and control of the liquid level can be realized.
The external liquid level meter is an instrument that measures the liquid level from the outside of the container using the principle of sonar ranging and “micro-vibration analysis” technology.
Two small external level gauge ultrasonic sensors are installed on the bottom of the tank and the other on the side wall of the tank to compensate for density changes.
The signal of the external level meter sensor is converted by the microprocessor and output to the local display or user control system. Can calculate the height of the liquid in the tank and the volume of the liquid in the tank
The hydrostatic level transmitter encapsulates the diffused silicon oil-filled core in a stainless steel shell.
The front protective cap protects the sensor diaphragm. It can also make the liquid contact the diaphragm smoothly. The water wire is sealed with the housing. The ventilation tube is connected to the outside world in the cable. The internal structure is designed to prevent condensation.
Ultrasonic level Sensor is composed of a complete ultrasonic sensor and control circuit.
The ultrasonic wave emitted by the ultrasonic sensor is reflected by the liquid surface. The time required to return is used for calculation.
The temperature influence in the ultrasonic transmission process is corrected by the temperature sensor, which is converted into the distance between the liquid surface and the ultrasonic sensor.
Output 4mA-20mADC analog signal through LCD screen. Realize remote reading of field instruments.
The differential pressure liquid level transmitter is an electrical component that measures the high and low pressure difference, and then converts it into a current signal by the conversion component and transmits it to the control room.
Differential pressure liquid level transmitter is mainly used for liquid level measurement of closed pressure vessels.
The size of the differential pressure also represents the size of the liquid level height.
Use a differential pressure gauge to measure the differential pressure between the gas and liquid phases to know the liquid level.

The SI-VL Verabar Flow Meter is designed with an aerodynamic engineering structure and is a sensor element. The VERIS Verabar Flow Meter is a Insertion flow meter. A Verabar tube sensor is inserted into the pipe. When the fluid flows through the sensor, a high-pressure distribution zone is created in the forward direction of the flow. And a low-pressure distribution zone is created in the rear. Verabar Flow Meter can be used to measure dry gas, humid gas, liquid or vapor, without being limited by dielectric constant.
The insertion turbine sensor is matched with the display instrument to form an insertion turbine flowmeter. The insertion turbine flowmeter can be widely used in large-diameter pipeline source water, circulating water, purified water, etc. to measure the volume instantaneous flow and total volume of liquids.
Insertion turbine flowmeter features:
The insertion turbine flowmeter has strong resistance to impurities. The tangential impeller can release the suspended debris in the fluid at any time when it rotates. so that it does not wrap around the blades of the tangential impeller;
The structure and principle of the sensor and display instrument are very simple and intuitive, and it is very easy for users to master their use and maintenance technology;
It has high anti-electromagnetic interference and anti-vibration capabilities, small pressure loss, wide flow range, and low lower limit flow rate. The impeller has anti-corrosion function;
The sensor can be installed in the open air, and the entire sensor can be used in water for a long time. Horizontal, vertical and inclined pipes can be used;
Sensor with shut-off valve. There is no need to cut off the current during installation and disassembly;
The Ultrasonic Insertion Flow Meter consists of a converter and a pair of insert sensors. The Insertion sensor consists of a positioning base, a ball valve, and a sensor core. Principle: When ultrasonic waves pass through the liquid, the liquid has a slight influence on the insertion time. The change of the insertion time is proportional to the liquid flow rate.
Annubar Flow Meter is a no-equal solution with a patented, averaging pitot tube that delivers superior measurement accuracy over a wide flow range. This flow meter can measure multiple variables and is engineered with an integrated thermowell for temperature measurement. Its patented T-shaped sensor is capable of obtaining measurements via a single pipe penetration while maintaining a small profile in the pipe to reduce permanent pressure loss and increase energy savings.
Insertion Thermal Mass Flow Meter can simultaneously display flow rate (flow), temperature. Low flow rates are responsive, and high flow rates can achieve good accuracy. Even at high temperature, a good constant temperature difference can be obtained, and the stability is good. There are a variety of installation options to choose from, with a measuring range up to 180Nm/s.
If an insertion flowmeter is to be selected for a wastewater pipeline, an insertion electromagnetic flowmeter must be the first choice.
The Insertion wastewater flowmeter can be widely used to measure the flow of conductive fluids in tap water, steel, petroleum, chemical industry, electric power, industry, water conservancy, water administration and water resources. It can also measure corrosive conductive liquids such as acids, alkalis, and salts.
The Insertion sewage flowmeter is mainly composed of a measuring head (or measuring tube), an excitation system, an insertion rod, a junction box, a mounting base, and a sealing and positioning mechanism.
Measuring head (or measuring tube): The measuring head (measuring tube) is located at the particle point of the measured flow velocity in the pipeline, and is used to detect the flow velocity at this point. A measuring head (or measuring tube) is a tip or conduit made of insulating material on which a pair of electrodes is mounted. Except for the electrode tip or the inner wall of the measuring tube, other parts are insulated from the fluid to be measured.
Excitation system: The function of the excitation system is to generate a working magnetic field. It consists of an excitation coil and an iron core. It is insulating sealed into the insertion rod.
Insert rod: Made of stainless steel material. The measuring head and the measuring tube are fixed in the insertion rod. The excitation lead and electrode lead are sealed with the measured medium and connected to the junction box through the insertion rod. A direction indicator is welded on the insertion rod to ensure that the working magnetic field, the flow rate and the electrode connection are perpendicular to each other during installation, which meets the requirements of Faraday’s law of electromagnetic induction.
Junction Box: The junction box is located on the top of the sensor. The terminals in the junction box connect the sensor and the converter to each other.
Mounting base: The mounting base is welded on the pipeline under test, used to connect with the mounting ball valve and insert the part of the sewage flowmeter sensor.
Sealing mechanism: It consists of a compression thread seat made of stainless steel, a compression nut, a rubber washer and a positioning screw. It is used to seal and insert the sewage sensor, so that it can avoid a certain working pressure.
insertion flow meter for air/compressed air
If you choose an insertion flowmeter for an air line, or a compressed air line. Then the insertion thermal mass flow meter can be said to be the first choice.
If you need to measure high temperature air, or high temperature compressed air. Then another type of flow meter may need to be selected. Such as high temperature Annubar flowmeter.
The installation requirements of various insertion flowmeters vary. Here is a brief introduction to the standard installation of plug-in electromagnetic flowmeters:
The arrangement of instruments on the pipeline should be far away from the valve. Maintain a 10-diameter upstream intermediate pipe section and a 5-diameter downstream straight pipe section.
The on-site power supply needs to match the instrument power supply, generally a 24V rectifier. If there is no external power supply for the field measurement, an external power supply meter will be connected.
Pay attention to the flow direction of the measured liquid on the inner wall of the pipe. If the installation is reversed, the measured liquid will show a negative value.
The installation site should be cool and rain-proof. If it is often rained or immersed in water, the protection grade IP68 product should be selected.
The fluid flow in the pipeline should not be stopped if the process requires it. Media should not spill. A ball valve needs to be installed.
Different digital flow sensors include turbine, thermal mass, electromagnetic, ultrasonic, orifice plate, venturi. The different designs of the flowmeters have a variety of applications. With 4-20ma, RS485, or other output.
Then they all work differently. However, they can convert the flow signal into a digital display, or pulse, or 4-20mA signal.

Crude Oil Flow Meter refers to a type of flow meter that can accurately monitor and measure the flow of crude oil. Crude oil is an industrial raw material with complex physical and chemical properties. In the process of production, storage, transportation and trade, it is greatly affected by factors such as temperature, pressure and environment. Storage, transportation and handover not in accordance with standard specifications will lead to increased measurement errors and affect product quality.
Therefore, the flow measurement of crude oil has always been the focus and difficulty of the oil and gas extraction industry.
After years of service experience, Sino-Inst offers multiple crude oil flow meters. Including mass flowmeters, positive displacement flowmeters, turbine flowmeters, etc.
In terms of the medium to be measured, the crude oil containing impurities needs flow measurement, and the flow measurement of the working conditions with impurities itself is a big problem. Choosing the right crude oil flow meter is even harder.
Based on years of service experience, the following 7 type flowmeters are the types of flowmeters that we believe can effectively measure the flow of crude oil.
In order to realize the accurate measurement of crude oil production, real-time automatic measurement of incoming crude oil quality is the fundamental method.
The mass flow meter has high precision, easy to use and easy maintenance, and long service life. Crude oil production can be directly measured. It is supplemented by a computer real-time monitoring and measurement software system based on it. and utilize network resources. It can also realize remote real-time monitoring of the flowmeter.
The mass flow meter measures the crude oil quality, crude oil volume, water content, temperature and other data on the liquid pipeline in real time. It is displayed on the metering post through the on-site display instrument.
At the same time, the on-site display instrument transmits the relevant data signals to the on-site data storage and remote transmission equipment (industrial computer).
For the crude oil mass flowmeter used for single well measurement, due to the presence of some chemical substances in the measured medium, the flowmeter will cause scaling on the wall of the mass flowmeter measurement pipe after a period of operation.
The composition of scale is very complex, mainly composed of asphalt, wax, sulfide, carbide, etc. The scale on the inner wall of the measuring tube of the flowmeter will affect the accuracy of mass flow and density measurement, thereby affecting the normal measurement performance of the mass flowmeter and causing a relatively large measurement error.
To ensure the normal use of the mass flowmeter, the flowmeter must be cleaned and descaled regularly. Then re-calibrate to determine the new configuration parameters of the instrument before it can be put into use again.
It is well known that the oval gear flowmeter is especially suitable for the flow measurement of the medium with high viscosity such as heavy oil, polyvinyl alcohol, resin, etc. The oval gear flowmeter has high measurement accuracy. It is suitable for the measurement of high viscosity medium flow (generally the viscosity of the liquid to be measured is 2-3000Mpa.s).
But not suitable for fluids containing solid particles. If the measured liquid medium contains gas, it will also cause measurement errors.
Usually, the accuracy of the oval gear flowmeter can reach 0.5, which is a relatively accurate flow meter.
However, if the flow rate of the measured medium is too small, the influence of the leakage error of the oval gear flowmeter will be prominent. Sufficient measurement accuracy can no longer be guaranteed.
The working principle of the dual rotor flowmeter is done in the metering chamber. It is directly meshed by a pair of special toothed helical rotors. No relative slippage.
Although the pressure of the liquid acting on the two rotors is different. However, a pair of synchronizing gears installed on the two rotors always maintains an appropriate gap between the two rotors, ensuring that the rotors can rotate smoothly and synchronously.
Several cavities with known volumes are formed between the rotor and the casing. Under the action of the measured medium, the micro-pressure difference between the inlet and outlet of the flowmeter drives the two helical rotors to rotate in opposite directions. The helical rotor can output 8 times the volume of the cavity per revolution.
Therefore, the number of revolutions of the rotor is proportional to the cumulative flow of the fluid. The rotational speed of the rotor is proportional to the instantaneous flow rate of the fluid. Therefore, the number of revolutions of the rotor can be transmitted to the counter through the transmission gear system to directly display the liquid flow.
At the same time, it can also be converted into an electrical pulse signal by adding an electromechanical conversion device. Then pass to the secondary instrument or computer for remote display and control.
The repeatability and stability of the dual-rotor flowmeter are in a linear state, which meets the requirements of crude oil export.
The dual-rotor flowmeter has been popularized and applied in various crude oil gathering and transportation stations and external transportation measurement rooms in oilfields. Undertook the measurement task of 4400t/d crude oil export, and its measurement data has been recognized by both sides of the trade.
The target flowmeter adopts the latest force sensor as the measurement and sensitive transmission element. At the same time, the latest digital technology and microelectronic technology are applied. It is an intelligent flowmeter suitable for the measurement of fluids and gases with high viscosity, low Reynolds number and tiny particles.
The use of force sensors is the key to the true realization of high precision and high stability of this product.
The target flowmeter not only has the characteristics of traditional orifice plate, vortex flowmeter and other flowmeters without moving parts. At the same time, it has measurement accuracy comparable to that of positive displacement flowmeters. Coupled with its unique anti-interference, anti-impurity performance.
In addition to the target flowmeter can replace the conventional flowmeter and conventional fluid flow measurement. Especially in high viscosity, easy blocking, high temperature, high pressure, strong corrosion and other difficult flow measurement conditions have good application value.
At present, it has been widely used in flow measurement in various fields such as steel, oil, natural gas, electric power, papermaking, chemical industry, energy, food, environmental protection and so on.
Therefore, the target flowmeter is a good choice for measuring high viscosity crude oil.
As long as the Reynolds number fits within the measuring range of the target flowmeter, it can be measured. Viscosity changes do not need to be considered. In addition, it can be equipped with a temperature sensor for density correction, which can ensure good measurement accuracy.
Turbine flowmeters can measure media such as special oils.
There are many varieties of oil, edible oil, peanut oil, diesel oil, gasoline, etc. are all oils. Turbine flowmeters measure the flow of liquids. However, it is not recommended to use it for measurement of too viscous liquids. Because the turbine flowmeter uses the principle of impeller rotation to measure the flow, and too viscous liquid will affect the rotation of the impeller.
Turbine flow meters can measure low temperature and non-viscous special oil. If the user’s working condition is measured on site, it is a special type of high temperature type oil. Nor can it be measured with a turbine flowmeter. The turbine flowmeter can only measure the working temperature when the ambient temperature on site is 120℃.
Therefore, the user chooses the turbine flowmeter to measure crude oil, and needs to choose according to the actual working conditions.
Magnetic Flow Meter is a flow meter that measures the flow of conductive fluids. Abbreviated as EMF, also called Electromagnetic flowmeters. It is a kind of Volumetric flow meter. A magnetic flow meter measures the velocity of conductive liquids moving through a pipe or conduit. In the wastewater treatment industry, Magnetic Flow Meter is the best flow meter choice.
The split-type electromagnetic flowmeter can also measure high-viscosity fluids. Based on the principle of electromagnetic flowmeter and other factors, this is theoretically true, but it also depends on the specific site.
In addition to measuring the flow of general conductive liquids, the split-type electromagnetic flowmeter can also measure liquid-solid two-phase flow, high-viscosity liquid flow and volume flow of salt, strong acid, and strong alkali liquids.
The differential pressure flow meter is measured by the working principle that there is a certain relationship between the pressure difference and the flow rate when the medium fluid flows through the throttling device. Differential pressure (DP) flow meters are the most widely used form of flow measurement products today. Including: integrated orifice flowmeter, average velocity tube flowmeter, venturi tube, wedge flowmeter, underwater flowmeter, orifice plate, orifice carrier assembly, nozzle flowmeter.
Differential pressure flowmeters always have unexpected advantages in measuring complex working conditions.
For example: Wedge throttling device is a new type of throttling device developed by our company. , Its special structure, non-clogging, solid structure, long life, can be used to measure liquid, gas and steam.
It is especially suitable for flow measurement of fluids with low flow rate, high viscosity, dust or solid particles. Such as measuring crude oil, fuel oil, residual oil, coal tar, waste water, carbon black solution and other fluids.
Flowmeters are the most commonly used instruments in oil exploration enterprises. The selection of flowmeters used in many production sites in oil fields is not reasonable, and some have installation errors, resulting in excessive measurement errors, and some cannot meet the needs of production or crude oil transfer measurement.
Many forms of flowmeters can measure crude oil, but when choosing a model based on experience and simply considering the purchase cost, you may lose the opportunity to choose the most suitable meter.
For example, the flow range of the instrument does not match the actual flow, and the instrument with high precision is selected for places with low measurement requirements.
It can be seen that the correct selection and use of flow meters is not an easy task. To choose a crude oil flowmeter correctly and efficiently. The following five factors must be considered, namely: performance requirements, physical properties of crude oil, installation requirements, environmental conditions and costs.
When selecting a flowmeter, the performance requirements to consider include: instantaneous flow, cumulative flow, degree, repeatability, linearity, flow range and range, pressure loss, output signal characteristics and response time.
Different measurement purposes have different options in terms of flowmeter performance. Such as crude oil trade settlement measurement requirements are relatively high.
Continuous measurement process control usually requires good reliability and repeatability. Sometimes a wide range of degrees is also required, and the requirements for measurement degrees should be placed in a secondary position.
The oilfield production site does not require the flowmeter to have too high accuracy, but it has good adaptability to the physical properties and working conditions of crude oil.
The operation of the crude oil flowmeter is affected by factors such as crude oil temperature, oil delivery pressure, crude oil density, crude oil viscosity, and flow rate.
The physical properties of crude oil will change to some extent with the changes of temperature and pressure.
When crude oil is measured by a flow meter, the volume of crude oil will be affected by changes in temperature, pressure, viscosity and other factors.
Among them, temperature is one of the most influential parameters in flow meter measurement. Changes in temperature can cause changes in a series of parameters, which change the volume, density, viscosity of the crude oil and the gap between the flowmeter housing and internal components, thus resulting in changes in leakage flow.
If the temperature is lowered, the paraffin and coke in the crude oil adhere to the inner wall of the shell and parts. This changes the volume of the metering chamber of the flowmeter. It directly affects the measurement accuracy of the flowmeter.
Flow meters of different principles have very different installation requirements. For example, differential pressure and turbine flowmeters require a long upstream straight pipe section, and some flowmeters do not have this requirement or have lower requirements. Some flowmeters need to consider the installation location and medium flow direction, maintenance space, installation direction, etc.
The measurement performance of the flowmeter is greatly affected by the installation conditions, and the reason for the large error of the flowmeter. Part of it is caused by poor installation.
Factors to be considered in the installation are: the installation direction of the flowmeter, the flow direction of the crude oil, the upstream and downstream straight pipe sections, the valve position, vibration, electromagnetic interference and maintenance space.
The ambient conditions of the meter and its expected changes, including ambient temperature, humidity, safety, and electrical interference, should be considered in the flowmeter selection process. The electronics of the meter and some of the meter’s flow sensing portion are affected by changes in ambient temperature.
For example, the size of the flow meter housing changes, and the heat transfer through the meter housing changes the density and viscosity of the fluid. When affecting the display meter electronics, it will degrade measurement performance. Sometimes the conversion display part and the flow sensor are installed in different places to ensure that the electronic components are not affected by temperature.
High humidity will accelerate atmospheric corrosion and electrolytic corrosion and reduce electrical insulation, and low humidity is prone to static electricity. These can have an effect on the circuit part of the flowmeter and sometimes even cause a malfunction.
In terms of economy, it is not comprehensive to consider only the purchase cost of the instrument, and other costs should also be considered. Such as accessories purchase costs, installation costs, maintenance and flow meter verification costs, operating costs and spare parts costs. Trade settlement measurement should also compare the economic losses caused by measurement errors.
The operating cost of the flowmeter is mainly the energy consumption during operation. Some flowmeters are powered by dry batteries, and the cost of battery consumption is also considerable. Pumping costs are a hidden cost that is often overlooked.
The maintenance cost is the cost required to maintain the normal operation of the measurement system after the instrument is installed and put into use, mainly including maintenance labor and spare parts. Instruments with moving parts generally require more maintenance work, such as regular replacement of wear-resistant bearings, shafts, rotors, transmission gears, etc.
The selection of crude oil flowmeter should comprehensively consider the five factors of instrument performance, fluid characteristics, installation conditions, environmental conditions and economy.
Encounter the phenomenon that the physical properties of crude oil, especially the viscosity-temperature characteristics, are not very clear. Special units should be invited to do a complete set of crude oil tests and make a physical property report.
Consult with the flowmeter manufacturer or technical department about the adaptability of various flowmeters and the influence of physical property changes on the performance of the flowmeter. Choose a flowmeter that meets your needs.

After the Pressure Transducer is installed, how should I wire it? Pressure sensor wiring refers to the electrical connection of the pressure sensor. A pressure transmitter is a conversion device that converts a pressure signal into an analog signal or a digital signal. Common signals include 4-20mA, 0-10V, 0-5V and other signals. The wiring methods of these signals generally include two-wire system, three-wire system, and four-wire system.
Many beginners struggle with sensor/transmitter wiring issues. Worry that the wrong connection will cause damage to the sensor/transmitter and affect the accuracy of the measurement. This article will discuss with you the wiring of pressure sensor/transmitter. Teach you how to deal with the wiring problems of two-wire, three-wire and four-wire sensors/transmitters.
Pressure transducer is also called pressure transmitter. A pressure transmitter is a device that converts pressure into pneumatic or electric signals for control and remote transmission. It can convert physical pressure parameters such as gas and liquid sensed by the load cell sensor into standard electrical signals (such as 4~20mADC, etc.). It can be used to supply secondary instruments such as indicating alarms, recorders, and regulators for measurement and indication. and process regulation.
4-20mA means that the minimum current is 4mA and the maximum current is 20mA.
The industry generally needs to measure various non-electrical physical quantities, such as temperature, pressure, speed, angle, etc. They all need to be converted into analog electrical signals before they can be transmitted to the control room or display equipment hundreds of meters away. This device that converts physical quantities into electrical signals is called a transmitter. The most widely used in the industry is to use a 4-20mA current to transmit analog quantities.
Because 4-20mA signals are least affected by electrical noise and resistance in the signal line, these sensors are best used when signals must be transmitted over long distances. These sensors are typically used in applications where the lead must be 1000 feet or more.
When we talk about 2-wire, 3-wire and 4-wire transmitters, we are primarily referring to the way the transmitter is electrically connected and powered. Here are their basic differences:
2-wire transmitter:
The power and signal outputs share two cables.
Usually the output is a 4-20mA current signal.
Since it requires only two cables, installation is relatively simple and low-cost.
Widely used in most process control applications.
3-wire transmitter:
There are usually two wires for power and one wire for output signals.
The output is usually voltage type, such as 0-10V.
Compared with 2-wire transmitters, 3-wire transmitters have separate power supplies and signals. Therefore, they may be more suitable in certain applications.
4-wire transmitter:
There are two wires for power and two wires for signal output.
Can output voltage or current signal, such as 4-20mA or 0-10V.
Due to their separate power and signal lines, 4-wire transmitters can often offer more functionality and performance, such as higher accuracy, remote configuration or HART communication.
Pressure sensor pinout refers to the pin layout or connection definition of the pressure sensor. You may also have heard of “4 pin pressure sensor” or “3 pin pressure sensor”.
The pin definition of the pressure sensor will tell the user the function of each pin or terminal. For example, which is the positive power supply (V+ or VCC), which is the ground (GND), which is the signal output, etc. Understanding these definitions is critical to properly connecting and using pressure sensors.
Here are some common pin definitions:
V+ or VCC: positive power supply. The sensor requires a power input. GND or V-: Negative power supply or ground wire. OUT or SIGNAL: signal output. This is the electrical signal output that the sensor converts into based on the measured pressure. Other pins: Some pressure sensors may have pins with other functions, such as temperature output, I2C or SPI communication interface, etc.
“Instrument wire system” refers to the number of wires used for instrument power supply and standard signal transmission.
The name of the wire system is only after the birth of the two-wire transmitter.
This is the result of the widespread application of electronic amplifiers in instruments. The essence of amplification is an energy conversion process, which cannot be separated from power supply.
Therefore, the first appeared is the four-wire transmitter. That is, the two wires are responsible for the power supply. The outer two wires are responsible for outputting the converted and amplified signals (such as voltage, current, etc.).
The wiring of the two-wire transmitter is shown in the figure. Power supply is 24VDC. The output signal is 4-20mA. The load resistance is typically 250Ω. The 24V supply has the lowest negative wire potential. It’s the public point.
The smart transmitter can also load the FSK keying signal of the HART protocol on the 4-20mA signal. Some digital display meters have transmission function or 24V power supply function. The function is similar to that of a two-wire transmitter.
The power supply and current signal loop of the two-wire transmitter are: The positive terminal of the 24V power supply → the positive terminal of the transmitter → the negative terminal of the transmitter → the positive terminal of the digital display meter → the negative terminal of the digital display meter → the negative terminal of the 24V power supply, the digital display meter receives the current signal. If a resistor R is connected in parallel with the positive and negative terminals of the digital display. The digital display meter receives the voltage signal.
The positive terminal of the power supply of the three-wire transmitter uses one wire. Use a line for the positive end of the signal output. The negative terminal of the power supply and the negative terminal of the signal share a line. as the picture shows. The power supply is mostly 24VDC, and the output signal is mostly 4-20mA.
The power loop of the three-wire transmitter is: 24V power supply positive terminal→transmitter positive power supply wiring V+ terminal→transmitter negative terminal (common terminal)→24V power supply negative terminal.
The current signal loop is: Transmitter’s current output I+ positive terminal → digital display meter positive terminal → digital display meter negative terminal → transmitter’s negative terminal (common terminal), the digital display meter receives the current signal.
If a resistor R is connected in parallel with the positive and negative terminals of the digital display meter, the digital display meter receives the voltage signal.
The power supply and signal of the four-wire transmitter use two wires each, and the power supply and the signal work separately. As shown in the figure, most of the power supply is 220VAC, and there are also 24VDC. The output signal is mostly 4-20mA.
The current signal loop of the four-wire transmitter is: The current output positive end of the transmitter → the positive end of the digital display meter → the negative end of the digital display meter → the negative end of the transmitter, the digital display meter receives the current signal.
If a resistor R is connected in parallel with the positive and negative terminals of the digital display meter, the digital display meter receives the voltage signal.
The working principle of the pressure transducer is to convert the weak non-electrical pressure-pressure variable collected by the sensor into a transmissible standardized signal output.
At the same time, it is enlarged to supply secondary instruments such as indicating alarms, recorders, and regulators for measurement, indication and process adjustment.
The converted electrical signal has a certain continuous functional relationship (usually a linear function) with the pressure variable.
The pressure transmitter is mainly composed of three parts: the sensitive element, the sensing element and the measurement conversion circuit.
Two-wire transmission has specific requirements for its minimum supply voltage, output current, and transmitter power consumption.
Only when these three conditions are satisfied in the design can the two-wire transmission be realized. The four-wire system requirements are not as high as the two-wire system.
Therefore, the two-wire system and the four-wire system have different requirements for the electronic components of the whole circuit.
For the two-wire instrument, the output signal is mostly 4-20mA (there are also frequency signal output).
But the four-wire instrument has more output signals, such as current signal 4-20mA, 0-10mA, voltage (millivolt) signal, frequency signal, etc.
For a 2-wire pressure transmitter, there are usually two wires. The positive wire is connected to the positive pole of the power supply and outputs the signal, and the negative wire is connected to the negative pole of the power supply or ground. For 3-wire or 4-wire pressure transmitters, connect the power supply wire and signal output wire respectively according to the instructions in the manual.
Pressure transmitters usually have 2, 3 or 4 wires. It depends on the model and function.
A common electrical output from a pressure transmitter is a 4-20mA current output. But there are also models with 0-10V, 0-5V and other voltage outputs.
Yes, the pressure transmitter requires a power supply. A 2-wire transmitter supplies power and transmits signals simultaneously via its two wires. 3-wire and 4-wire transmitters usually have dedicated power supply lines.
The 3-wire 4-20mA transmitter usually has a dedicated power supply line, and the other two lines are the ground wire and the signal output line. This is different from a 2-wire transmitter, where power and signal share two wires.
Connect the signal output line of the pressure transmitter to the analog input of the VFD. Make sure the transmitter ground wire is connected to the VFD ground. In the parameter settings of the VFD, configure the corresponding analog input as pressure feedback, and adjust the parameters as needed.
Pressure Transducer Wiring is actually very simple. Generally, when the pressure transmitter is used and installed, there will be an installation manual, which can be installed directly according to the manual.
Pressure transmitters include capacitive pressure transmitters and resistive pressure transmitters. A pressure transmitter is a device that converts the pressure of a gas or liquid into a usable electrical signal.
The pressure transmitter can be divided into two-wire system, three-wire system and four-wire system according to the wiring method.
The pressure transmitter has two power lines and two signal lines. The power supply is connected to 24v DC. The simple detection method is to use an ammeter or voltmeter to connect both ends of the signal line.
After the pressure transmitter power supply is connected, the ammeter will have 4ma current or the voltmeter will have 0v or 1V voltage. Read more about: What Is 0-10V Signal Output?
The current transmitter generally has 4 terminals. Two are wired. The other two do not need to be wired. The DC24V power line of the transmitter is also a 4-20mA signal feedback line.
That is to say, the AI point of your secondary meter or DAS (data acquisition system) should have a DC24V feed output.
Generally, the 4-20mA pressure transmitter is a 2-wire system, powered by 24V, and outputs a 4-20mA current signal. After the pressure transmitter arrives at the scene, many people do not know how to wire it. This is a very painful and headache.
In fact, when you open the back cover of the pressure transmitter, you will see four terminals. OUT positive and negative and TEST positive and negative. Here we take OUT positive and negative.
TEST positive and negative is the factory, the manufacturer used to calibrate the pressure transmitter. It is not necessary to control the function of the two terminals when using it on site.

Non Contact Level Transmitters are now more and more widely used in industrial level monitoring. We most often provide customers with non-contact radar level transmitters and ultrasonic level meters. Both liquids and solids can be measured with Non Contact Level Transmitters. There is no need to dig the level probe deep into the measured medium. The sensitive elements measured by Non Contact Level Transmitters are not in contact with the liquid being measured. It can be used in special occasions that contact measuring instruments cannot meet. Such as the medium with high viscosity, strong corrosiveness, strong pollution and easy crystallization.
In order to choose the most suitable level sensor, we not only need to know the properties and state of the liquid being measured. It is also necessary to understand the advantages and disadvantages of different level sensors. in order to select the most suitable sensor. Next, let’s briefly introduce the common non-contact liquid level measurement methods and their characteristics.
Common non-contact measurement methods mainly include ray level meter, ultrasonic level meter, laser ranging sensor and radar level meter.
The rays emitted by nuclear radiation (such as gamma rays, etc.) have strong penetrating ability. And through the medium of different thickness has different attenuation characteristics. The nuclear radiation level meter uses this principle to measure the liquid level.
The nuclear radiation source of the nuclear radiation level gauge is installed outside the oil tank with a point or narrow structure. The elongated nuclear radiation source detection element is also installed outside the oil tank. It can realize the detection of dynamic change of liquid level.
In addition to measuring with nuclear radiation rays, neutron rays can also be used to measure liquid level.
The ray level meter is very convenient to install and has high measurement accuracy.
Because it does not have any parts in direct contact with the measured object. It is especially suitable for measurement problems that cannot be solved by traditional measuring instruments.
The propagation speed of ultrasonic waves in the same medium is relatively constant. Reflection occurs when it encounters the surface of the object being measured. Based on this principle, an ultrasonic level meter was developed. It calculates the liquid level height by detecting the time difference between ultrasonic transmission and reflection. Therefore, it is easily affected by the energy loss of ultrasonic propagation.
The ultrasonic level meter has the characteristics of easy installation and high flexibility. However, when used in environments containing steam and powder layers, the detection distance will be significantly shortened. Not recommended for use in absorbing environments such as foam.
In addition, the accuracy of the ultrasonic level meter is slightly lower than that of the radar level meter, and the price is moderate.
Its measurement principle is similar to that of an ultrasonic level meter. Just use light waves instead of ultrasound. The emission sensor emits laser light and irradiates it to the liquid surface to be measured. Reflection occurs at the liquid surface, and the receiving sensor receives the reflected light. Convert the time from transmit to receive to level.
The beam of a laser is narrow, so its spot is small and concentrated. Therefore, it is very suitable for containers with narrow openings and measurement objects with high temperature and high viscosity.
Laser ranging sensor level meters are easy to install, calibrate, and flexible. The price is relatively affordable, and it can be used for continuous or limit alarms of bulk materials or liquid levels.
If it is a transparent liquid and oil, it is necessary to add a reflective buoy on the liquid surface before it can be measured. Not suitable for use in foam or steam environment (cannot penetrate foam or easily disturbed by steam), fluctuating liquid (easy to cause malfunction), vibration environment, etc.
Radar level meters usually use the principle of frequency modulation radar. Utilize synchronous FM pulse technology. Mount the microwave transmitter and receiver on the top of the tank. A frequency-modulated microwave signal is emitted to the liquid surface.
When the echo signal is received, due to the delay of the round-trip propagation time. The transmission frequency has changed. The two signals are mixed and processed, and the difference frequency of the obtained signal is proportional to the distance between the tank top and the liquid surface.
The radar level meter has a large measurement range and is not affected by harsh weather environments. And easy to install, low maintenance and other advantages,
Especially suitable for high viscosity or high pollution products, such as asphalt. Radar level meters provide high measurement accuracy and do not require regular maintenance and recalibration. But the installation is more complicated and the price is relatively high.
Very short microwave pulses with very low energy are transmitted and received through the antenna system. The radar wave runs at the speed of light. The operating time can be converted into level signals by electronic components. A special time extension method can ensure stable and accurate measurement in a very short time.
Electromagnetic waves propagate in the air at the speed of light. The distance between the radar level gauge and the surface of the material can be expressed by the following formula:
D = (1/2)*CT
In the formula:
D ———the distance between the radar level gauge and the surface of the material;
C ———Speed of light
T ———Pulse time.
Then the liquid level is: L = E-D
In the formula:
L — liquid level;
E ———The total height of the tank;
D ———Air height.
Even in the presence of false reflections, the new micro-processing technology and the unique ECHOFOX- software can accurately analyze the level echo. By inputting the size of the container, the distance value can be converted into a signal proportional to the level. The instrument can be debugged with empty positions.
The working principle of the ultrasonic level sensor is:
Ultrasonic transducer (probe) emits high-frequency pulse sound waves, and the surface of the measured level (material) is reflected back. The reflected echo is received by the transducer and converted into an electrical signal. The propagation time of the sound wave is proportional to the distance from the sound wave to the surface of the object.
The relationship between the sound wave transmission distance S and the sound speed C and the sound transmission time T can be expressed by the formula: S=C×T/2.
The probe part emits ultrasonic waves, which are then reflected by the liquid surface. The probe part is received again. The distance from the probe to the liquid (object) surface is proportional to the elapsed time of the ultrasonic wave: hb = CT2 Distance [m] = time × speed of sound/2 [m] The temperature compensation formula of sound velocity: Ambient sound velocity = 331.5 + 0.6 × temperature
Ideally, we should be able to use a liquid volume sensor to directly measure the volume of the liquid in the container. Well, but in fact, there is no mature…
