How it works: Insertion Type Ultrasonic Flow Meter-Heat Meter
Introducing our new Insertion Type Ultrasonic Flow Meter-Heat Meter—Mono/Multi-Channel. This advanced device measures both flow and heat. Each channel is accurate, and for multi-channel products, channels support each other, improving accuracy and stability.
The measurement is based on the signal correlation method. Multi-channel products can use multiple channels at once, which greatly reduces the impact of turbulence. This makes the device more adaptable and accurate for different situations, ensuring reliable small flow and heat measurements.
Our product has a fast ARM core processor, with a response time under 0.1 seconds, making it over 10 times faster than regular flow meters. It’s great for measuring high-viscosity oils, chemical products, and ultrapure water flow. Additionally, it can connect to two temperature sensors, so it can be used as a flow or heat meter.
An insertion type flow meter is a device that measures the flow of liquid or gas in a pipe. It’s installed by inserting a probe or sensor directly into the flow stream, without requiring the pipe to be cut or altered. This makes it easy to install, maintain, and remove, while providing accurate flow measurements for various applications.
The two types of ultrasonic flow meters are Doppler and Transit Time. Doppler flow meters measure the frequency shift of sound waves as they reflect off particles in the flow, while Transit Time flow meters measure the time it takes for sound waves to travel between two sensors, with the flow affecting the travel time.
The main difference between insertion and inline flow meters is how they’re installed. Insertion flow meters are installed by inserting a probe or sensor into the flow stream, while inline flow meters require the pipe to be cut and the meter to be placed directly into the pipeline. Inline flow meters usually offer higher accuracy, but insertion flow meters are easier to install and maintain.
To install an ultrasonic flow meter, first select the proper location on the pipe, ensuring it’s free of bends, valves, or obstructions. Clean the pipe surface, apply coupling gel, and mount the flow meter’s sensors according to the manufacturer’s instructions. Connect the sensors to the flow meter’s electronics, and then configure the device settings, including pipe diameter, material, and other parameters. Finally, test the flow meter to ensure accurate readings.

The metal tube float flowmeter is mainly composed of two parts: the measuring tube and the indicator. The measuring tube includes a conical tube or orifice, guide, stopper, float, and other components. The indicator includes a magnetic follower system, pointer, dial, circuit, and other components.
The measured medium flows through the measuring tube from bottom to top. The upper and lower ends of the float generate differential pressure to form a rising force. When the rising force of the float is greater than the weight of the float immersed in the flowing fluid, the float rises, and the annular gap area increases. Annular gap When the fluid velocity drops rapidly, the differential pressure at the upper and lower ends of the float decreases. The ascending force acting on the float decreases. Until the ascending force balances with the weight of the float immersed in the fluid, the float stabilizes at a certain position. The height of the float is that Corresponds to the size of the measured medium flow.
The float has built-in magnetic steel. When the float moves up and down with the medium, the magnetic field changes with the movement of the float.
a. For the in-situ type, the follow-up magnet in the in-situ indicator is coupled with the magnet in the float. It rotates and drives the pointer at the same time, and the current flow rate is indicated by the dial.
b. For the smart type, the follower magnetic steel in the smart indicator is coupled with the magnetic steel in the float. It rotates and drives the sensing magnetic steel and pointer at the same time. The magnetic field change is converted into an electrical signal through a magnetic sensor.

Rotameter flow meter applications
The metal Rotameter flow meter is suitable for the flow measurement of small-diameter and low-velocity media. It can measure most media such as gas and liquid.
The metal Rotameter flow meter can measure the instantaneous flow and cumulative flow of gases and liquids, including corrosive acid, alkali, and salt solutions. It is especially preferred when the flow is low or when a purely mechanical or inconvenient power supply is required.
Rotameter flow meters are mostly vertical installation, bottom entry, and top exit type, and can also be installed horizontally. The price is higher. Let me show you a sample.
This is an explosion-proof type for measuring corrosive liquids.
This is a smart type. It can measure gas and liquid. There should be no impurities.
This one is installed horizontally to measure nitrogen. It is purely mechanical to display instantaneous flow rate.
Installed vertically on a vibration-free pipe. The fluid flows through the meter from bottom to top.
When measuring dirty fluids, a filter should be installed upstream of the meter
If the fluid itself is pulsating, a buffer tank can be installed. If the instrument itself oscillates, a damping device can be installed.
The gas in the instrument must be drained of the liquid.
The control valve in the measurement and control system should be installed downstream of the flowmeter. When used for gas measurement, ensure that the working pressure is not less than 5 times the pressure loss of the flowmeter. In order to make the flowmeter work stably.
Before installing the metal rotor flowmeter, the welding slag in the pipeline should be purged. Remove the stop element from the flowmeter when installing. When using after installation, open the control valve slowly. Avoid impact damage to the flowmeter.
If the measurement requires a wide range of flow, the range exceeds 10 o’clock. Two floats of different shapes and weights can be placed in one instrument. Take the frivolity reading when the flow is small. After the float reaches the top, take the reading of the heavy float. The range can be expanded to 50-100.
Liquid meters are usually calibrated with water, and gas meters are calibrated with air. The fixed value is in the engineering standard state. If the fluid density, gas pressure, and temperature of the use conditions are inconsistent with the calibration. Make necessary conversions.

Mass flow controller, namely Mass Flow Controller (abbreviated as MFC). Not only has the function of a mass flow meter. More importantly, it can automatically control the gas flow. That is, users can set the flow rate according to their needs. MFC automatically keeps the flow constant at the set value. Even if the system pressure fluctuates or the ambient temperature changes, it will not deviate from the set value.
Simply put, the mass flow controller is a steady flow device. It is a gas steady flow device that can be set manually or automatically controlled by connecting with a computer.
Mass flow meter, namely Mass Flow Meter (abbreviated as MFM). It is an instrument for accurately measuring gas flow. The measured value is not inaccurate due to temperature or pressure fluctuations, and does not require temperature and pressure compensation.
The mass flow controller is composed of a flow sensor, a diverter channel, a flow regulating valve and an amplifying controller.

Specifications of Gas mass flow controller
Medium
Suitable for gas, weakly corrosive gas. For example: nitrogen, air, not suitable for ammonia
The mass flow meter uses the principle of capillary heat transfer thermometry to measure the mass flow of gas (without temperature and pressure compensation).
The flow signal measured by the sensor heating bridge is sent to the amplifier for amplification. The amplified flow measurement voltage is compared with the set voltage.
Then amplify the difference signal to control the regulating valve. Through closed-loop control to control the flow-through, and make it equal to the set flow. The flow divider determines the flow of the main channel.
The picture shows the working principle diagram of the MFC and the flow indicator connected:
The detected voltage of the flow rate output by the controller is directly proportional to the quality of the gas flowing through the channel. The full-scale detection output voltage is 5VDC. The detection range of the gas mass flow controller is 2~100% full scale (the turndown ratio is 50:1) The flow resolution is 0.1% of full scale.
Note: When the “valve control” line of the gas mass flow controller is set to the “cleaning” position, it can also be used as a gas mass flow meter. At this time, the output value of the flow detection output voltage may reach more than 10VDC.
It should be noted that once the output voltage exceeds 5VDC, the flow detection voltage and the actual flow rate are not linearly corresponding.
When cleaning, the flow rate display is inaccurate. Moreover, the flow rate may increase and the display decrease. But these will not damage the mass flow controller.
Positive displacement flow meter, also known as fixed displacement flow meter.
It uses mechanical measuring elements to continuously divide the fluid into a single known volume part. The fluid volume flow rate is measured according to the number of times that the measuring chamber is filled and discharged with the volume part of fluid successively.
Float type flowmeter, also known as rotameter.
It is a kind of variable area flowmeter. In a vertical tapered tube that expands from bottom to top. The gravity of a float with a circular cross-section is borne by the hydrodynamic force. So that the float can rise and fall freely in the cone tube.
It is based on the differential pressure generated by the flow detector installed in the pipeline. Known fluid conditions and the size of the test room and pipeline to calculate the flow of the meter.
A non-streamline vortex generator is placed in the fluid. The fluid is alternately separated on both sides of the generator to release two series of regularly staggered vortex meters.
It is the main type of velocity flow meters. It uses a multi-blade rotor (turbine) to sense the average flow velocity of the fluid. In order to derive the flow or total meter.
A meter that measures the flow rate by detecting the effect of fluid flow on the ultrasonic beam (or ultrasonic pulse).
Electromagnetic flowmeter.
Electromagnetic flowmeter is an instrument for measuring conductive liquid made according to Faraday’s law of electromagnetic induction. Electromagnetic flowmeter has a series of excellent characteristics. It can solve the problems that other flowmeters are not easy to apply, such as the measurement of dirty flow and corrosive flow.
Thermal flow meter.
The thermal flow meter sensor contains two sensing elements. A speed sensor and a temperature sensor.
They automatically compensate and correct for gas temperature changes.
The electric heating part of the instrument heats the speed sensor to a certain fixed value higher than the temperature of the working condition. A constant temperature difference is formed between the speed sensor and the sensor that measures the temperature of the working condition.
When the temperature difference is kept constant, the energy consumed by electric heating can also be said to be the heat dissipation value. It is proportional to the mass flow rate of the gas flowing through it. It is suitable for the measurement of single gas and fixed ratio multi-component gas.
Coriolis flowmeter.
The principle is to use the Coriolis force generated when the fluid flows in the vibrating tube. The force is measured directly or indirectly to obtain the fluid mass flow rate.
What we usually call a mass flow controller, its full name is a thermal gas mass flow controller, or MFC for short.
The full name of mass flow meter is thermal gas mass flow meter, referred to as MFM.
They are an instrument that precisely measures gas flow. Its measured value will not be inaccurate due to changes in temperature or pressure.
A mass flow meter is a meter for measurement and monitoring. The mass flow controller not only has the function of mass flow meter. More importantly: it can automatically control the flow of gas. That is to say, the user can set the flow rate according to the needs of the situation. The flow controller automatically keeps the flow constant at the set value. Even if the system pressure fluctuates or the ambient temperature changes, it will not deviate from the original set value.
Simply put, a mass flow controller is a steady flow device. It is an automatic control gas flow stabilization device that can be manually set or connected with a calculator.
In general, if only the gas flow is measured or monitored, a mass flow meter can meet the requirements.
And if it is necessary to control the gas flow, a mass flow controller is required.
In some measurement occasions, both can be used. Such as the measurement of capillary flow capacity, when measuring flow at constant pressure, use a mass flow meter. When measuring constant flow and pressure, a mass flow controller is required.
Note that when the mass flow controller is in the cleaning state, it can also be used as a mass flow meter. It’s just that the pressure drop is larger than that of ordinary mass flow meters.
The volume flowmeter can only measure the volume flow directly, if you want to measure the mass flow, if you give a fixed density value during configuration. This makes it impossible to detect density dynamically. Less accurate.
Mass flow controllers/flowmeters measure gases that are not affected by temperature and pressure.
Mass flow controller MFC not only has the function of mass flow meter. What’s more, it can automatically control the gas flow. The flow rate can be set according to actual needs.
The MFC automatically keeps the flow constant at the set value. Even if the system pressure fluctuates or the ambient temperature changes. It will not deviate from the error range of the set value.
Mass flow controllers can be used to control all kinds of gases. Including corrosive gases and special gases.
But pay attention to the use of corrosive gases and special gases. Proper selection of model and seal material is required.
When ordering, the user needs to declare the gas to be used. In order to avoid serious losses due to wrong selection or selection of sealing materials.
Usually, the wet material of the mass flow controller contacting the working gas is 316L stainless steel, polytetrafluoroethylene and sealing materials. Sealing materials are divided into two categories: metal seals and rubber seals. Metal seal materials are generally corrosion-resistant materials such as stainless steel, gold or nickel.
The MFC with metal seal can be used for any gas in principle, including various corrosive gases and special gases.
For strong corrosive gases such as boron tribromide, boron trichloride, and hydrogen fluoride, and metal oxide gases used in MOCVD, it is recommended to use a metal-sealed MFC.

Gear flow transmitter is a type of positive displacement flow transmitter. It is a high-precision transmitter for measuring volume flow.
With the flow of the medium, the gears mesh and rotate. Under the action of the fluid flow, a pressure difference is formed at both ends of the instrument inlet and outlet. There is no need for a power supply. A pair of gears rotate freely. The cavity between the gears is filled with liquid. Discharge and measure the number of revolutions of the gear to know the flow of liquid and liquid flowing through the instrument.
Figure 1 Schematic diagram of fluid flow
The rotation speed of the round gear transmitter is detected by the sensor coil in the signal amplifier mounted on the watch case. The signal amplifier is not in contact with the measured medium. When the transmitter gear cuts the magnetic field lines generated by the permanent magnet in the housing, it will cause the magnetic flux in the sensing coil to change.
The sensing coil sends the detected magnetic flux periodic change signal to the preamplifier, amplifies and reshapes the signal, generates a pulse signal proportional to the flow rate, and sends it to the unit conversion and flow integration circuit to obtain and display the cumulative flow value. At the same time, the pulse signal is sent to the frequency current conversion circuit, which converts the pulse signal into an analog current quantity, and then indicates the instantaneous flow value.
The round gear transmitter has high machining accuracy and precise installation. The rotation of the gear is scanned non-contact, and each tooth generates a pulse with a very high resolution. Cylindrical gear transmitters can measure very small flow and quantify the small volume of liquid.
Oval gear flow meters (also known as displacement flow meters, gear flow meters) are a type of positive displacement flow meters, which are the most accurate type of flow meters. It uses a mechanical measuring element to continuously divide the fluid into a single known volume part, and measures the total flow volume according to the number of times that the metering chamber is filled and discharged with the volume part of the fluid successively and repeatedly. The oval gear flowmeter can be made of different materials (cast iron, cast steel, 304 stainless steel, 316 stainless steel), and is suitable for flow measurement in the chemical, petroleum, pharmaceutical, electric power, metallurgy and food industries.
The measurement principle of the gear of the Cylinder Gear flow meter is similar to that of the oval gear flow meter. But the gear shape is different.
Oval Gear Flow Meter Advantages and Disadvantages
The oval gear flowmeter uses the principle of volumetric type. Suitable for testing various viscous liquids. Flow measurement of heavy oil, polyvinyl alcohol, resin and other high-viscosity media.
Advantages:
The measurement accuracy of the oval gear flowmeter is high. The basic error is generally ±0.5%R. Special ones can reach ±0.2% R or higher. It is especially suitable for use in the field where high-precision measurement is required.
It has no influence on the measurement accuracy when measuring the distortion of the flow velocity field of the rotating flow and the pipeline choke. There is no requirement for the front straight pipe section.
The oval gear flowmeter can be used to measure high-viscosity fluids. Wide flow range. It is generally 10:1 to 5:1. Special ones can reach 30:1 or greater.
With direct reading of on-site flow. It can measure the cumulative total without external power supply. The display is clear and the operation is convenient.
The oval gear flowmeter is a combination of measuring elements. The indirect method of volumetric flow measurement. Compared with other flow meters that use velocity to derive flow. Oval gear flow meters have the following disadvantages:
The design of the measurement structure is complicated. Large and bulky. In particular, the flowmeter with a larger caliber is bulky. Compared with other general flow meters (such as orifice flow meters, float flow meters, electromagnetic flow meters, vortex flow meters). The measured medium type, medium working condition (temperature, pressure), and caliber are relatively limited. The scope of adaptation is narrow.
Not suitable for high and low temperature occasions. Because of the thermal expansion and deformation of parts at high temperatures, the material becomes brittle at low temperatures. The usable temperature range is -30～+180℃. The maximum pressure is 10MPa.
The oval gear flowmeter is only suitable for clean single-phase fluids. When the fluid contains particles or dirt, a filter must be installed upstream. Not only increases the pressure loss, but also increases the maintenance work. If measuring liquids containing gas, a gas separator must be installed.
Poor safety performance during measurement. If the measuring element is stuck in motion, the fluid cannot pass through. The cut-off piping system cannot be used.
During the measurement process, the pulsation caused by the flow of fluid during the measurement process. Large-diameter flowmeters can also generate noise. Even the pipes vibrate.
Gear flow meters are a type of positive displacement flow meters. It is used for precise continuous or discontinuous measurement of the flow or instantaneous flow of liquid in the pipeline. It is especially suitable for the flow measurement of heavy oil, polyvinyl alcohol, resin, and other high viscosity media.
Oval gear flow meter (also known as displacement flowmeter, gear flowmeter) is a type of positive displacement flowmeter. It is a category with higher accuracy in flow meters. It uses mechanical measuring elements to continuously divide the fluid into individual known volume parts. The total flow volume is measured according to the number of times that the metering chamber is filled and discharged with this volume of fluid successively and repeatedly. The oval gear flowmeter can be made of different materials (cast iron, cast steel, 304 stainless steel, 316 stainless steel), and is suitable for flow measurement in the chemical, petroleum, pharmaceutical, electric power, metallurgy, and food industries.

The ultrasonic water meter adopts the time difference method to measure the flow. That is, an ultrasonic transducer is installed at the upstream and downstream of the measuring channel (pipe section) to transmit and receive ultrasonic signals.
Because the ultrasonic signal and the water flow signal are superimposed, the propagation speed of the sound wave is different in the forward and reverse flow. Therefore, the running time of the ultrasonic signal emitted by different transducers in the water is different. The fluid can be calculated by measuring the difference of the time The flow rate. Then it is converted into a flow rate, so as to realize the measurement of the flow rate.
There are two transducers on the top of the flow tube. Transducer A transmits an ultrasonic signal to transducer B (downstream), while transducer B transmits an ultrasonic signal to transducer A (countercurrent). Downstream and The countercurrent ultrasonic signal forms a certain time difference in the transmission process. In the case of the calibrated cross-sectional area of the pipe diameter and the length of the standard measuring pipe, the flow rate of the meter is calculated by the calculation chip on the integrator.

The measurement accuracy of the ultrasonic flowmeter is very high. Almost no interference from various parameters of the measured medium. In particular, it can solve the flow measurement problems of strong corrosive, non-conductive, radioactive and flammable and explosive media that other instruments cannot. So what causes the inaccurate measurement of the ultrasonic flowmeter? The following are the reasons for the inaccurate measurement: The influence of pipeline parameter equipment on the accuracy of ultrasonic flowmeter measurement. The influence of upstream and downstream straight pipes on the accuracy of ultrasonic flowmeter measurement. The influence of couplant on measurement accuracy. The influence of the installation position of the ultrasonic flowmeter transducer on the measurement accuracy.
Common types of ultrasonic flow meters ①According to the measurement principle. Ultrasonic flowmeters are now the most commonly used methods for measuring flow rates are the propagation velocity difference method ultrasonic flowmeter and the Doppler frequency shift method ultrasonic flowmeter. The propagation velocity difference method can be divided into three types: time difference method, phase difference method and acoustic cycle frequency difference. ②According to the installation method of the transducer. There are two types of ultrasonic flowmeters: fixed ultrasonic flowmeter and portable ultrasonic flowmeter. The transducer installation methods of the fixed ultrasonic flowmeter can be divided into: A tube-segment ultrasonic flowmeter integrating transducer and measuring tube; The external clamp ultrasonic flowmeter with the transducer clamped on the outer wall of the measuring tube; Insertion Type Ultrasonic Flow Meter in which the transducer passes through the outer wall of the pipe and directly contacts the medium; The transducer is attached to the inner wall of the large pipeline ultrasonic flowmeter. ③According to the channel of propagation. Ultrasonic flow meters can be divided into single-channel ultrasonic flow meters and multi-channel ultrasonic flow meters. Among them, multi-channel can be divided into two-channel ultrasonic flowmeter, ultrasonic flowmeter, four-channel and eight-channel ultrasonic flowmeter.
The ultrasonic water meter adopts the time difference method to measure the flow. That is to say, an ultrasonic transducer is installed in the upstream and downstream of the measurement channel (pipe section) for mutual transmission and reception of ultrasonic signals.
Because the ultrasonic signal is superimposed with the water flow signal. Make the sound waves travel at different speeds in the forward and reverse flow. Therefore, the ultrasonic signals emitted by different transducers have different running times in water. By measuring the difference in time, the flow rate of the fluid can be calculated. And then converted into flow, so as to achieve flow measurement.

Clamp-on flow meter mainly refers to an ultrasonic external clamp-on flow meter. The ultrasonic sensor is clamped on the pipeline. It can be measured without changing the pipeline. Clamp-on flow meter can be a handheld host, portable host, etc.
Clamp on Ultrasonic Flow Meter adopts the measurement principle of the time difference method. It uses the ultrasonic wave emitted by the sensor to propagate in the flowing fluid. The sound wave propagation speed in the downstream direction will increase, and the backward direction will decrease. In the same propagation distance, there will be different transmission times. According to the difference between the transmission time and the measured The relationship between fluid velocity measures the fluid velocity.
The flow rate of the fluid is different in different positions in the tube. The flow rate in the center of the tube is faster than the flow rate near the wall of the tube. The flow velocity distribution of the fluid in the pipeline can be represented by the flow velocity cross-sectional distribution diagram.
By setting the flowmeter and considering the cross-sectional distribution of the flow velocity, the average flow velocity can be calculated. Then the volume flow of the fluid can be obtained according to the cross-sectional area of the pipe.

The working principle of gas Roots flowmeter
Gas Roots flowmeter is a positive displacement flow meter.
When the gas passes through the flow meter, the pressure difference generated between the inlet and the outlet acts on a pair of waist wheels connected with high-precision synchronous gears to drive the waist wheels to rotate.
During this period, the enclosed space formed between the waist wheel and the inner wall of the housing and the gland is periodically inflated and exhausted by a metering chamber. The speed of the waist wheel is proportional to the volume of gas passing through the flow meter.
The rotation of the waist wheel is transmitted to the mechanical counter or output flow pulse signal through the magnetic coupler, so as to accumulate the volume flowing through the metering cavity to achieve the purpose of metering.

Roots meter is also called waist flow meter. The working principle is the same as that of the oval gear flowmeter, and the structure is also very similar, except that the shape of the rotor is slightly different.
The rotor of the Roots meter is a pair of waist-shaped wheels without teeth. During the rotation, the two waist wheels do not directly contact and maintain a small gap. The driving is completed by the meshing gear that is sleeved outside the shell and coaxial with the waist wheel. This has obvious advantages compared with oval gear flow meters.
Oval gears have large meshing contact wear and are greatly affected by the cleanliness of the measured fluid. Easy to damage and reduce accuracy.
The Roots meter is linked by an additional drive gear, so there is no contact between the measuring elements during operation. Therefore, the wear during operation is very small, and high measurement accuracy can be achieved. It can keep the long-term stable parts of the flowmeter.
The structure of the waist wheel flowmeter can be divided into vertical and horizontal according to the working state:
The structure of the waist wheel includes a pair of waist wheels and a combined waist wheel composed of two pairs of waist wheels at an angle of 450 to each other.
The combined waist wheel flowmeter runs smoothly, which can greatly reduce the pressure fluctuation in the pipeline.
Generally, large-diameter flowmeters use vertical or horizontal combined waist wheels to reduce or eliminate pipeline vibration caused during flow measurement.
The rotor line of the waist wheel flowmeter is more reasonable, allowing the measurement of fluids containing tiny particles. Can be used for gas and liquid measurement. It is a positive displacement flowmeter that has been rapidly developed and widely used in recent years.
In addition to being used for industrial measurement, Roots meter is also used as a standard flow meter to calibrate other types of flow meters. The accuracy can reach ±0.1%.
