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.

Hydrostatic level measurement is often used for tank level measurement. Hydrostatic level measurement is one type of continuous level measurement.
What Is Hydrostatic Pressure?
Hydrostatic pressure sensors are used to measure the level or fill height of liquids. Hydrostatic pressure measurement is suitable for liquid level measurement due to the static pressure effect of non-flowing fluids. This physical principle describes the effect of the gravity of a stationary (i.e. non-flowing) liquid on the measurement point. This gravity is often described as “hydrostatic pressure”.
Sino-Inst offers a variety of Hydrostatic level senors for industrial level measurement. If you have any questions, please contact our sales engineers.

Pros & Cons of Hydrostatic level measurement system
About Hydrostatic level transmitter advantages and disadvantages, we do a simple analysis here. If you want to know more about the advantages and disadvantages of level transmitters. Please refer to Sino-Inst Level Transmitters.
Advantages
High measurement accuracy;
The ultra-high range can be customized up to 1000 meters.
Easy to install;
The signal can be transmitted remotely;
The corrosion of various media can be resisted by choosing different materials;
Suitable for explosion-proof occasions;
Low cost;
Disadvantages
The measurement signal needs to be converted;
When the measuring range is greater than 5 meters, it is impossible to measure the high temperature medium temperature exceeding 125 ℃;
If you choose a submersible pressure transmitter. You must lower the device into the medium by cable. Until you reach the bottom of the tank, reservoir or underground resources, or until you reach the required zero level. Then, run the cable from the oil tank or water tank to the control system. Connect the level probe to the PLC accordingly.
If you have turbulent media, you should use an extra tank weight to stabilize the level probe in the media. To obtain a stable pressure reading. To prevent the cable from any mechanical damage. You can use the cable clamp to fix the cable on the top of the water tank. Or when connecting the cable to the control system.
If you choose a standard pressure transmitter. Simply screw the transmitter into the threaded hole on the bottom or side of the tank. Then, connect the transmitter to the PLC with the appropriate cable connector. Or if cable connection is selected, connect the transmitter directly to the control system.
Capacitive liquid level transmitter is the core sensor working principle of a transmitter. Refers to an instrument that measures differential pressure by detecting changes in capacitance on both sides of the sensing diaphragm. Theoretically, it can measure the pressure and differential pressure in any form, including liquid level. The reason why it is called a liquid level transmitter is only because its installation method is specially designed for liquid level measurement. The essence of the capacitive liquid level transmitter is a differential pressure transmitter.
Hydrostatic level sensor refers to a method of measuring liquid level using the principle of Hydrostatic pressure. Liquid level height × medium weight = pressure difference between liquid level and upside. This method of measurement requires the use of a differential pressure transmitter. If this differential pressure transmitter is designed to be more suitable for liquid level measurement, it is called a liquid level transmitter.
A submersible pressure transducer or a flush pressure sensor measures the height-dependent weight-force of the liquid column, also known as hydrostatic pressure. This pressure measurement is directly proportional to the liquid level respectively liquid column, at the measuring point of the pressure sensor. It is, therefore, necessary, for the measurement of level, that the pressure sensor is placed as close as possible to the level of the vessel’s bottom. The measured hydrostatic pressure then directly corresponds to the height of the liquid column, from the ground-level measurement point to the surface-level of the medium. So, the filling height is calculated from the distance of the medium surface, to the measuring point by the pressure measurement. The weight force of the liquid column, thus the hydrostatic pressure, however, is not only directly proportional to the filling height but also varies with the specific gravity of the medium and the force of gravity. Read more about: Differences! Static pressure vs dynamic pressure vs total pressure
Hydrostatic pressure is the pressure that a homogeneous fluid acts on an object. This is a omnidirectional force that is evenly applied to all parts of the surface of the object. Increased hydrostatic pressure will reduce the volume of the stressed object, but will not change its shape
Hydrostatic level transmitter is actually a type of pressure transmitter. Hydrostatic level transmitter is the application of pressure transmitter to liquid level measurement. The submersible Hydostatic pressure level transmitter is based on the principle that the measured liquid static pressure is proportional to the height of the liquid. Piezoresistive effect using diffused silicon or ceramic sensitive elements. Convert static pressure into electrical signal. After temperature compensation and linear correction. Convert to 4-20mADC standard current signal output. In order to achieve liquid level measurement.
Usually we measure the liquid level by measuring the pressure. When the liquid level transmitter is put into a certain depth in the measured liquid, the pressure formula of the sensor facing the liquid surface is: Ρ = ρ.g.H + Po. In the formula: P: the pressure on the liquid face of the transmitter Ρ: measured liquid density G: local gravity acceleration Po: atmospheric pressure on the liquid surface H: Depth of transmitter into liquid At the same time, the pressure of the liquid is introduced into the positive pressure chamber of the sensor through the air-conducting stainless steel. Then connect the atmospheric pressure Po on the liquid surface to the negative pressure chamber of the sensor. To offset Po on the back of the sensor, the pressure measured by the sensor is: ρ.g.H. Obviously, by measuring the pressure P, the liquid level depth can be obtained. Of course, if the liquid level is measured, the pressure value can also be converted. Read more What is a diaphragm seal?
Yes. If it is an open tank use a transmitter. If it is pressurized, 2 pressure transmitters must be used (the difference in the software is the liquid level height). The range unit of the transmitter is preferably mmH2O. If the medium is not water, its density must also be known. This allows for span correction (top transmitters do not do span correction). Generally, a double-diaphragm differential pressure transmitter is used to detect the liquid level.

Product Applications: Sulfuric acid, hydrochloric acid, hydrofluoric acid; Corrosive liquids such as liquid alkali, xylene and acetone; Wastewater; Sludge pits, clarifiers, digesters; Alum tanks; Chemical storage tanks; Oil tanks; Lime slurry; Sumps; Reservoirs;
The basic working principle of Hydrostatic Level Sensor is static pressure level measurement.
In liquid, the pressure generated at a certain depth is generated by the weight of the medium itself above the measurement point. It is proportional to the density of the medium and the local acceleration of gravity.
The formula P = ρgh reflects the proportional relationship between them.
Where P = pressure, ρ = medium density, g = gravity acceleration, h = depth of measurement point.
Therefore, the physical quantity measured by the input liquid level gauge is actually pressure. It can be understood by the calibration unit mH2O of the input level gauge. The actual liquid level must be obtained by conversion after knowing the two parameters of density and gravity acceleration. In the industrial field, such conversion is usually performed by a secondary instrument or PLC.
The Hydrostatic Level Sensor mainly measures corrosive liquids such as hydrochloric acid, hydrogen peroxide, etc. Or chemical and electroplating wastewater. Mainly used in measuring corrosive media. It has the advantages of strong corrosion resistance and stable performance.

Repeat the above steps two or three times. Until the signal is normal;
The adjustment is completed. Tighten the protective cover.
Submersible Level Transmitter installation and precautions
The transmitter probe has an M20 × 1.5 interface, which can be screwed directly on the wall of the container or pipeline. Can also put the transmitter into the pool or other liquids. Cable lead to display instrument, secondary instrument or control room. Note that the cable part on the ground needs to be protected or elevated. If there is sediment at the bottom of the liquid to be tested. The transmitter should be raised or filtered for protection.
A. Instructions for installation of input liquid level sensor:
Sludge and oil residue are easy to deposit on the bottom of the tank. It is recommended to move the measuring probe at a certain height away from the bottom of the tank (cabin). To avoid debris blocking the probe.
When the medium in the tank fluctuates greatly and the air guide cable is very long. The probe should be fixed with a sleeve. To prevent the probe from swinging and affecting the measurement accuracy.
When the transmitter is installed, the bending radius of the air guide cable should be greater than 10 cm. Avoid excessive bending to damage the air guide cable.
The ground terminal of the input liquid level transmitter should be reliably grounded. The power shield should be connected to it.
The installation direction of the transmitter is vertical. The installation position of the input type (probe) should be far away from the liquid inlet and outlet and the agitator.
If the medium in the tank has large vibration, wire should be wrapped around the transmitter (probe). Use steel wire to reduce shock to avoid breaking the cable.
B. How to install the input liquid level sensor (probe) to prevent damage to the diaphragm?
When the Submersible Level Transmitter is installed in a stationary deep well or pool. Usually the steel pipe with inner diameter Φ45mm is fixed in water. Make small holes at different heights on the opposite side of the liquid flow direction, so that the medium can enter the tube smoothly. Then put the input liquid level transmitter into the steel pipe and use it.
It is best to choose a regulated power supply to supply power separately. The stability of the power supply affects the performance index of the transmitter. It is best to control its error to less than one-fifth of the allowable error of the transmitter. For products with special power supply requirements, special power supplies must be connected.
The signal cable of the liquid level transmitter should adopt shielded cable. Prevent electromagnetic interference.
Connect the transmitter according to the correct wiring method. The power-on time should be between 15 and 30 minutes.
If the liquid level transmitter is installed in the pool, water tower and other occasions. You can sink its probe underwater. Keep away from locations where the water velocity is too fast.
In the installation of liquid level transmitters with large fluctuations such as submersible pumps, it is best to use the method of inserting steel pipes. The steel pipe should be fixed firmly. A hole should be made in the steel tube at every interval. The position of the steel pipe should be far away from the water inlet and outlet.
The junction box should be fixed firmly. Or install a fixed bracket. It must be protected from dry and shaded places and must not be exposed to rain.
Protect the ventilation cable. It must not be bent, blocked or damaged. Extra cables can be coiled nearby.
The liquid level transmitter installed outdoors must also take lightning protection measures.
Submersible Level Transmitter for Wastewater
The wastewater treatment process involves many occasions where the liquid level needs to be measured. Also due to the characteristics of the sewage treatment process itself. Need to choose the appropriate level sensor according to the characteristics of each process and medium.
The sensor must be suitable for measuring sewage. The acid, alkali and small particles in the sewage have no effect on the measurement accuracy and life. The sensor has high measurement accuracy. Easy to install. Easy to adjust. The level gauge display is intuitive and has analog output and alarm output functions.
Generally speaking, magnetic float level sensor, ultrasonic level sensor and Submersible Level Transmitter can be used to measure the sewage level.
The magnetic float level sensor is to convert the displacement of the magnetic float with the change of liquid level into a simulated linear standard signal output. The measurement accuracy can generally reach 1.5. When used for sewage measurement, the oil and suspended particles in the sewage will gradually adhere to the wall of the level gauge pipe. Over time, the amount of floating objects increases and the friction increases. The floating ball cannot rise and fall freely as the liquid level changes. It cannot be measured.
The ultrasonic level sensor is based on the relationship between the distance from the ultrasonic probe to the surface of the measured object and the time. This type of liquid level gauge is almost not limited by the measured medium, but has a blind zone, which is suitable for the level measurement of the large “H” value of the storage silo. For the level measurement of sewage pits, due to the existence of blind areas, it has a greater impact on the accuracy of the measurement.
Submersible Level Transmitter (cable static pressure liquid level transmitter) uses ceramic or diffused silicon sensors. The sensor goes directly into the measured liquid. The static pressure of the liquid medium directly acts on the sensor diaphragm. The static pressure is proportional to the height of the measured liquid. This level transmitter is small. Easy installation and low cost.
Compare the advantages and disadvantages of the above level gauges. Most customers will choose Submersible Level Transmitter.
Hydrostatic pressure level sensor (Submersible Level Transmitter) is a pressure sensor that measures liquid level based on the principle of static pressure measurement. It can also be called “static pressure liquid level gauge, liquid level transmitter, liquid level sensor, water level sensor”
What is the water level sensor?
The water level sensor is an instrument that can convert the water level parameter of the measured point into the corresponding power signal in real time. It is mainly composed of a fully sealed isolation membrane oil-filled sensor and a built-in high-performance microprocessor. There are many types of water level sensors. There are three common types of ultrasonic liquid level sensors, servo liquid level sensors and static pressure liquid level sensors. Due to the differences in their working principles and performance, their applications are also different.
What is ultrasonic level sensor?
The ultrasonic level sensor is a non-contact liquid level sensor. Ultrasonic sensors are sensors developed using the characteristics of ultrasound. Ultrasound is a mechanical wave with a vibration frequency higher than that of sound waves, which is generated by the vibration of the transducing wafer under the excitation of voltage. It has high frequency, short wavelength and small diffraction phenomenon. In particular, it has good directivity, and can be ray and directional propagation. Ultrasound has a great ability to penetrate liquids and solids. Especially in the opaque solids of sunlight, it can penetrate a depth of tens of meters.

For water level measurement, hydrostatic level sensor is a low cost type. Different types of measuring cells are used in level measurement based on the hydrostatic principle.
Lightning protection, anti-corrosion, explosion-proof optional. IP68 is optional.
Sino-Inst offers a variety of Hydrostatic Level sensors for industrial level measurement. If you have any questions, please contact our sales engineers.
Hydrostatic level sensors measure the pressure generated by a static head of liquid. Use hydrostatic level sensors to measure fluid levels in Tanks. And applications like storage tanks, processing vessels, header tanks, pump inlet heads, and others. Hydrostatic pressure is used to determine the liquid height.
The basic working principle of Hydrostatic Level Sensor is static pressure level measurement.
In liquid, the pressure generated at a certain depth is generated by the weight of the medium itself above the measurement point. It is proportional to the density of the medium and the local acceleration of gravity.
The formula P = ρgh reflects the proportional relationship between them.
Where P = pressure, ρ = medium density, g = gravity acceleration, h = depth of measurement point.
Therefore, the physical quantity measured by the input liquid level gauge is actually pressure. It can be understood by the calibration unit mH2O of the input level gauge. The actual liquid level must be obtained by conversion after knowing the two parameters of density and gravity acceleration. In the industrial field, such conversion is usually performed by a secondary instrument or PLC.
The Hydrostatic Level Sensor mainly measures corrosive liquids such as hydrochloric acid, hydrogen peroxide, etc. Or chemical and electroplating wastewater. Mainly used in measuring corrosive media. It has the advantages of strong corrosion resistance and stable performance.

What is a hydrostatic gauge? Or, What is a hydrostatic level sensor?
Hydrostatics is the science of fluids not in motion.
A hydrostatic level sensor is a form of a level probe, that is used especially for level monitoring, by measuring the hydrostatic pressure, in a virtually static liquid at a pre-determined level of submersion.
A hydrostatic level sensor is a submersible pressure transmitter, that has a pressure diaphragm, where the inner side of the diaphragm is vented to atmospheric pressure, through a vent tube in the cable, and the outer side is in contact with the liquid, and measuring the static pressure of the liquid column above the transmitter.
This static pressure is basically caused by the weight of the fluid on top of the transmitter, and is used to calculate the level of the liquid.

How does a hydrostatic level sensor work? Or How is hydrostatic pressure measured?
When considering a new level sensor for level measurement applications, it is often hard to find information on how the different types of level sensors,like the hydrostatic level sensors respectively hydrostatic pressure sensors, are working.
Recently, I explained level measurement by using the hydrostatic pressure measurement.
In closed geometries, such as enclosed tanks and vessels, generally, flush pressure sensors or pressure transmitters are used, which can be screwed into the vessel from the outside.
Pressure sensors are therefore particularly suitable, in applications of free-standing tanks and vessels.
A submersible pressure transduceror a flush pressure sensor measures the height-dependent weight-force of the liquid column, also known as hydrostatic pressure.
This pressure measurement is directly proportional to the liquid level respectively liquid column, at the measuring point of the pressure sensor.
It is, therefore, necessary, for the measurement of level, that the pressure sensor is placed as close as possible to the level of the vessel’s bottom.
The measured hydrostatic pressure then directly corresponds to the height of the liquid column, from the ground-level measurement point to the surface level of the medium.
So, the filling height is calculated from the distance of the medium surface to the measuring point by the pressure measurement.
The weight force of the liquid column, thus the hydrostatic pressure, however, is not only directly proportional to the filling height but also varies with the specific gravity of the medium and the force of gravity.
The simplicity of using a hydrostatic level sensor makes it the instrument of choice wherever level needs to be measured, no matter if in a vented tank, vessel, lake, river, or reservoir.
In most cases, it is suspended by the cable to the desired level of measurement, or just submerged and allowed to sink to the bottom of the resource.
It does not matter what the structure of the tank, basin, or natural geometry is or if it has any obstructions, ledges, or complex shape, a hydrostatic level sensor will always measure the pressure of the liquid unaffected by such disturbances.
As the hydrostatic level sensor commonly is a gauge pressure sensor, it automatically compensates for the atmospheric pressure changes, so the pressure measured represents only the pressure of the liquid, caused by the liquid’s specific gravity and the vertical distance to the surface.
Therefore, the hydrostatic level sensor accurately measures the level of the liquid, by calculating the distance from the measuring point to the surface level via the measured pressure.
A hydrostatic level sensor may be calibrated in the meters water column to allow for standard gravity or local gravity.
For very high accuracy level monitoring often the temperature of the media may also be considered to take the temperature effects on the specific gravity into account.
The hydrostatic level sensor is a specialized sensor for level monitoring, most commonly used in the water and wastewater industry.
Its simple use and reliable and accurate measurement technology make it one of the most commonly used level sensors by far.
The hydrostatic level sensor is based on the principle that the measured static pressure of the liquid is proportional to the height of the liquid. It is made with an advanced isolated diffused silicon sensitive element or a ceramic capacitive pressure sensitive sensor. The static pressure is converted into an electrical signal. After temperature compensation And linear correction. Converted into a standard electrical signal (generally 4 ~ 20mA / 1 ~ 5VDC). The hydrostatic level sensor can also be called “static pressure liquid level gauge, liquid level transmitter, liquid level sensor, water level sensor”.

How is hydrostatic pressure measured?
The hydrostatic pressure can be measured by a pressure sensor. Principle of hydrostatic pressure measurement: When the liquid level transmitter is put into a certain depth in the liquid to be measured, the pressure on the liquid-facing surface of the sensor. The formula is: ρ = ρ .g.h + po In the formula: p: pressure on the liquid face of the transmitter ρ: measured liquid density g: local gravity acceleration PO: atmospheric pressure on the liquid surface h: the depth of the transmitter into the liquid At the same time, the pressure of the liquid is introduced into the positive pressure chamber of the sensor through the air-conducting stainless steel. Then connect the atmospheric pressure PO on the liquid surface to the negative pressure chamber of the sensor. To offset so on the back of the sensor, the pressure measured by the sensor is: ρ .g.h. Obviously, by measuring the pressure p, the liquid level depth can be obtained. Extended reading: Static pressure vs dynamic pressure vs total pressure

Hydrostatic pressure refers to the pressure on the surface of an object when it is stationary or moving at a uniform speed. Its unit is pa. Static pressure plus dynamic pressure equals total pressure. In fluid mechanics, it mainly refers to the following three types: The pressure is generated by the fluid at rest. The pressure is perpendicular to the direction of fluid movement when the fluid is flowing. The gauge pressure value is measured in the fluid without being affected by the flow velocity.

How does a water pressure sensor work?
The core of the water pressure sensor is usually diffused silicon. The working principle of the water pressure sensor is that the pressure of the measured water pressure directly acts on the diaphragm of the sensor, so that the diaphragm produces a micro-displacement proportional to the water pressure. As a result, the resistance value of the sensor changes. Use an electronic circuit to detect this change. And convert and output a standard measurement signal corresponding to the pressure.
About the working principle of water pressure sensor, WIKA made a great introduction. Of course, if you need to know more about how the water pressure sensor works, please refer to Wikipedia: Pressure sensor
A pressure sensor may also be used to calculate the level of a fluid. This technique is commonly employed to measure the depth of a submerged body (such as a diver or submarine), or level of contents in a tank (such as in a water tower).
For most practical purposes, fluid level is directly proportional to pressure. In the case of fresh water where the contents are under atmospheric pressure, 1psi = 27.7 inH20 / 1Pa = 9.81 mmH20.
The basic equation for such a measurement is:
where P = pressure, ρ = density of the fluid, g = standard gravity, h = height of fluid column above pressure sensor
If the transmitter is used for a period of time, it may cause a change in metering performance. There will be zero drift, and the measurement error will increase. Therefore, it is necessary to perform regular calibration.
The accuracy of the calibrator used for calibration should be more than 3 times the required calibration accuracy.
Use the pressure calibrator to input the standard pressure values of 0%, 25%, 50%, 75%, and 100% of the range to the transmitter in the forward and reverse directions.
Check whether the current output signal is within the allowable accuracy range. If it is out of tolerance, it needs to be adjusted.
The adjustment method is as follows (4 ~ 20mA output):
(1) Input a standard pressure of 4mA with a pressure calibrator. Adjust the ZERO (zero) potentiometer. Make the 4mA current output within the accuracy range; (2) Input a standard pressure of 20mA with a pressure calibrator. Adjust the SPAN (range) potentiometer. Make the 20mA current output within the accuracy range; (3) ZERO and SPAN will contain each other. Repeat steps (1) (2) until the current output of 4mA point and 20mA point meets the accuracy requirements at the same time. Then check whether the current output of 25%, 50% and 75% range points meet the accuracy requirements. The transmitter is qualified if it meets the requirements.
Differental pressure liquid level sensor
SMT3151LT differential pressure level transmitter is usually used to measure the liquid level in a closed container. The differential pressure level transmitter uses the differential pressure generated by the gravity of the liquid to measure the liquid level in the container.
The high-pressure side measuring tube is always filled with water due to steam condensation, keeping the pressure constant. The low-pressure side measuring tube forms a communication device with the container. The pressure changes with the liquid level in the container.
Sino-Inst offers overs 100 DP transmitters, for liquid level, pressure measurement. Our differential pressure (dp) level transmitters suit to measeure water and other liquid level.
A wide variety of DP level transmitters are available to you, such as SMT3151LT Differential pressure level transmitter.
Water pressure sensors are usually used to measure the water level in the water tank or the rate of change of the water level. The sensor is mounted on top of an open tube submerged in the container.
As the water level rises, the air above the water in the tube is compressed, which increases the pressure on the sensor. An analog-to-digital converter (ADC) is used to convert the signal from the sensor to a digital value.
They can also be used to measure the pressure in running water pipes (for example, in a water supply system). It automatically determines whether it is necessary to start the pump to increase the flow rate.
They can be used to measure the depth of submerged objects. For example, in deep sea diving.
Of course, we can also calculate the liquid level based on water pressure. Or you can directly refer to our static pressure level transmitter.
Q & A
How does pressure sensor work?
What is the working principle of a pressure sensor? A pressure sensor works by converting pressure into an analog electrical signal. The demand for pressure measuring instruments increased during the steam age. When pressure sensing technologies were first manufactured, they were mechanical and used Bourdon tube gauges to move a needle, and give a visual indication of pressure. Nowadays we measure pressure electronically using pressure transducers and pressure switches.
What is a capacitive pressure sensor?
Capacitive pressure sensors typically use a thin diaphragm, as one plate of a capacitor. The applied pressure causes the diaphragm to deflect and the capacitance to change. You may like: Diaphragm Seal Pressure/ Differential Pressure Transmitters This change may or may not be linear, and is typically on the order of several picofarads out of a total capacitance of 50-100 pF. The change in capacitance may be used to control the frequency of an oscillator or to vary the coupling of an AC signal through a network. The electronics for signal conditioning should be located close to the sensing element, to prevent errors due to stray capacitance. Read more about Capacitive pressure transducer [What is & How does it work]
What are the various types of sensors used to measure pressure?
Pressure measurements can be taken to determine a range of different values, depending on whether the pressure is relative to the atmosphere, vacuum conditions, or other measuring factors. Pressure sensors are instruments that can be designed and configured to detect pressure across these variables.
Absolute pressure sensors are intended to measure pressure relative to a vacuum, and they are designed with a reference vacuum enclosed within the sensor itself. These sensors can also measure atmospheric pressure. Similarly, a gauge pressure sensor detects values relative to atmospheric pressure, and part of the device is usually exposed to ambient conditions. This device may be employed for blood pressure measurements. For more information on the differences between the gauge and absolute pressure. More about: Absolute Pressure Vs Gauge Pressure.
How to take off a high pressure sensor on thr liquid line?
Generally, the pressure sensor is installed behind the pressure valve. When you need to remove the pressure sensor, simply close the pressure valve. When purchasing a pressure transmitter, the manufacturer will recommend configuring a valve block. Or according to the measurement situation, install the pressure guiding tube. This can facilitate the installation and disassembly of the pressure transmitter, while ensuring continuous flow of the pipeline.
How do you test a pressure sensor?
There are 3 commonly used detection methods for pressure sensors. Hope it can help you. 1. Pressure test. The method of detection is to power the sensor. Use your mouth to blow the air hole of the pressure sensor. Use the voltage file of a multimeter to detect the voltage change at the output of the sensor. If the relative sensitivity of the pressure sensor is large, this amount of change will be significant. If there is no change at all, you need to use a pneumatic source to apply pressure. Through the above method, you can basically detect the condition of a sensor. If accurate testing is required, a standard pressure source is required. Give pressure to the sensor, and calibrate the sensor according to the pressure and the change of the output signal. And when conditions permit, the temperature detection of relevant parameters. 2. Zero point detection. Use the voltage range of the multimeter to detect the zero output of the sensor under no pressure. This output is generally a voltage of mV level. If it exceeds the technical specifications of the sensor, it means that the zero deviation of the sensor is out of range. 3. Detection of bridges. It mainly detects whether the circuit of the sensor is correct. It is generally a Wheatstone full-bridge circuit. Use the ohm file of the multimeter. Measure the impedance between the input terminals and the impedance between the output terminals. These two impedances are the input and output impedances of the pressure sensor. If the impedance is infinite, the bridge is disconnected. It means there is a problem with the sensor or the definition of the pin is not correct.
What is the difference between pressure switch and pressure transmitter?
Pressure Switch: When the pressure in the system is higher or lower than the rated safety pressure. The disc in the sensor moves instantaneously. Push the switch connector on or off by connecting the guide rod. When the pressure drops or rises to the rated recovery value, the disc resets instantly. The switch automatically resets. Or simply put, when the measured pressure exceeds the rated value, the free end of the elastic element is displaced. Push the switching element directly or after comparison. Change the on-off status of the switching element. To achieve the purpose of controlling the measured pressure. The elastic elements used in the pressure switch include single-turn spring tube, diaphragm, diaphragm box and bellows. Pressure Transmitter: When the pressure signal acts on the sensor. The pressure sensor converts the pressure signal into an electrical signal. Amplified by differential amplifier and output amplifier. Finally, the V / A voltage and current are converted into a 4-20mA standard current output signal in linear correspondence with the measured medium (liquid) level pressure.
Special products include micro-sized, ultra-micro-sized high-pressure high-temperature and flushing diaphragm models. To fit the space with narrow gaps.

Submersible pressure transducer installation
Precautions for the use and installation of the submersible level sensor:
1. When the liquid level transmitter is transported and stored, it should be restored to the original packaging and stored in a cool, dry and ventilated warehouse.
2. If an abnormality is found during use, turn off the power supply. Stop using it, and check it.
3. Connect the power supply according to the wiring instructions.
How to install the submersible level sensor ?
Total Time:
The ground terminal of the input liquid level gauge should be reliably grounded. The power shield should be connected to it.
When the transmitter is installed on the side, the bending radius of the air guide cable should be greater than 10 cm. Avoid excessive bending to damage the air guide cable.
In the occasions with large vibration. Wire can be wrapped around the transmitter. Use steel wire for shock absorption. So as not to break the cable.
The installation direction of the transmitter is vertical. The input installation position should be far away from the liquid inlet and outlet and agitator.
When measuring the level of flowing or agitated liquid. Usually the steel pipe with inner diameter Φ45mm is fixed in water. Then put the input level gauge into the steel pipe and use it. Make small holes at different heights on the opposite side of the liquid flow direction, so that the water can enter the pipe smoothly.
When the liquid level gauge is installed in a stationary deep well or pool, the steel pipe with an inner diameter of about Φ45mm is usually fixed in the water. Then put the input level gauge into the steel pipe and use it. Make small holes at different heights to allow water to enter the pipe.
When the medium fluctuates greatly and the air guide cable is very long. The probe should be fixed with a sleeve to prevent the probe from swinging and affecting the measurement accuracy.
Sludge, oil residue and other substances are easily deposited in the tank bottom or bilge. It is recommended to move the measuring probe at a certain height away from the bottom of the tank (cabin). In order to avoid debris blocking the probe.
If there is any problem with the submersible pressure transducer during use. You can call the Sino-Inst staff to get a timely solution.
Submersible pressure transducer is a hydrostatic pressure sensor. Because it can be put into water, the liquid level can be calculated by measuring the underwater static pressure, so it is also called throw-in water level transmitter / level transmitter /submersible water level sensor / level gauge. Submersible pressure transducer is based on the principle that the measured liquid static pressure is proportional to the height of the liquid. Use advanced isolated diffused silicon sensitive element or ceramic capacitor pressure sensitive sensor. Convert static pressure into electrical signal. After temperature compensation and linear correction. Converted into standard electrical signals (such as 4 ~ 20mA, etc.). Equipped with 2088 indicator head can also realize real-time display of on-site water level.
Precise level and temperature measurement with HART®communication
Measurement uncertainty of max. 0.5 %, long-term drift of 0.1 %.
And slight temperature errors make the SI-PCM261 a reliable measurement solution, for the monitoring of storage tanks and bodies of water.
The additional analog temperature output facilitates the compensation of a temperature-induced density error especially at temperatures of up to -40 … +80 °C [-40 … +176 °F].
The integrated HART® communication can be used for scaling the measuring range, and for the parameter isolation of unit, error signal, and others.
The reason for using a current signal is that it is less susceptible to interference. And the internal resistance of the current source is infinite. The wire resistance is connected in series in the loop without affecting the accuracy. And it can be transmitted over ordinary twisted pairs for hundreds of meters.
Due to explosion protection requirements, the upper limit is 20 mA: the spark energy caused by a current interruption of 20 mA is not sufficient to ignite the gas.
The reason why the lower limit is not set to 0mA is to detect a disconnection. During normal operation, the value will not be lower than 4mA. And when the transmission line is disconnected due to a fault, the loop current will drop to 0.
Usually, 20mA is used as the disconnection alarm value. There are two more reasons. One reason is to avoid interference. Another reason is that the two-wire system uses 4-20 mA of current. That is, the two wires are the signal line and the power line. The 4 mA is used to provide the quiescent operating current of the circuit for the sensor.
The modern electronic system guarantees not only a high accuracy in the long term. But also ensures a very long battery life thanks to the low power supply, low current consumption, fast response time and low-power output signals.
Safety also in hazardous areas
The optional intrinsically safe electronic system is authorized, according to the common international standards. And allows a safe worldwide application in explosive gases and vapours.

The basic working principle of Hydrostatic Level Sensor is static pressure level measurement.
In liquid, the pressure generated at a certain depth is generated by the weight of the medium itself above the measurement point. It is proportional to the density of the medium and the local acceleration of gravity.
The formula P = ρgh reflects the proportional relationship between them.
Where P = pressure, ρ = medium density, g = gravity acceleration, h = depth of measurement point.
Therefore, the physical quantity measured by the input liquid level gauge is actually pressure. It can be understood by the calibration unit mH2O of the input level gauge. The actual liquid level must be obtained by conversion after knowing the two parameters of density and gravity acceleration. In the industrial field, such conversion is usually performed by a secondary instrument or PLC.
The Hydrostatic Level Sensor mainly measures corrosive liquids such as hydrochloric acid, hydrogen peroxide, etc. Or chemical and electroplating wastewater. Mainly used in measuring corrosive media. It has the advantages of strong corrosion resistance and stable performance.
Well Water Level Sensor and oil pipe (water pipe) go down to install together:
The deep well liquid level transmitter should use the special ferrule fixing cable for the matching oil pipe (water pipe). Prevent crushing and damaging the cable. The sensor part should be installed vertically to prevent the sediment and other impurities from burying or blocking the transmitter probe part.
The three-way outlet part is filled with special sealant pad and sealant. Use a wrench to tighten the compression nut. Prevent air leakage.
The entire signal line leads to the interior of the power distribution cabinet. Prevent rainwater at the terminal from penetrating into the cable to cause damage. The transmitter is used for the installation of hydrology, seismic monitoring wells and reservoir dams.
When the transmitter is used alone for downhole measurement. When the cable length is greater than 100 meters, an additional load-bearing wire rope should be added. Go down with the signal cable together. Protect the signal cable to prevent the signal cable from being damaged due to excessive force.
Unscrew the protective cover. You can see the zero and full range resistors. External standard power supply and ammeter (above 0.2 pole). To adjust. Proceed as follows:
◆ In the case of no liquid in the transmitter. Adjust the zero resistor. Make it output current 4mA. ◆ Transmitter is filled to full scale. Adjust the full-scale resistor. Make the output current 20mA, ◆ Repeat the above steps two or three times. Until the signal is normal. ◆ The adjustment is completed. Tighten the protective cover.
