The thermal gas mass flowmeter is an instrument for measuring fluid flow by using the principle of heat conduction. The instrument uses constant temperature difference method to accurately measure the gas mass flow. The most important thing is that the range ratio of this flowmeter is very wide, which greatly meets the measurement needs of the owner.

The origin of the thermal gas mass flowmeter is from the hot wire anemometer. The temperature of the platinum heating wire has a proportional relationship with the change in the flow rate of the fluid: the faster the flow rate, the more heat is taken away.

With the development of new energy technology, natural gas is more and more widely used in many new energy industries, and the thermal gas mass flowmeter has become a suitable instrument for measuring high pressure gas measurement. Below we analyze from the perspective of product performance and installation cost, why the thermal gas mass flowmeter can become a suitable low degree meter in high pressure natural gas measurement.

When selecting a thermal mass flowmeter, several important factors should be taken into consideration to ensure it meets the requirements of the application and provides accurate and reliable measurements. Here are key points to pay attention to:

The thermal gas flowmeter adopts the principle of thermal diffusion, and the thermal diffusion technology is a technology with excellent performance and high reliability under harsh conditions. Typical sensing elements of thermal gas mass flowmeters include two thermal resistors (PT100), one is a speed sensor and one is a temperature sensor that automatically compensates for changes in gas temperature.

It has the advantages of small size, high digitization, easy installation, accurate measurement and so on.

Thermal gas mass flowmeters are a type of mass flowmeter specifically designed for measuring the flow rate of gases, while mass flowmeters, in a broader sense, can measure the flow rate of both gases and liquids. Here are some key differences between thermal gas mass flowmeters and other types of mass flowmeters:

The selection of flue gas flowmeter is a complicated but critical process, which is directly related to the accuracy of measurement results and the reliability of equipment. Here are some of the main factors to consider in the selection process:

Check Power Supply: Ensure that the flowmeter is receiving power from the power supply source. Verify that the power supply is operational, and check the connections between the flowmeter and the power source. If necessary, measure the voltage at the flowmeter terminals to confirm proper power supply.

Thermal gas mass flowmeter has certain operating procedures and precautions in use, and must pay attention to these points when in use:

Direct measurement of gas mass, without temperature, pressure compensation of gas flow measurement instrument, it represents the development trend of gas flow measurement. The thermal mass flowmeter sensor part is composed of two reference platinum resistance temperature sensors, using a bridge loop, one sensor measures the fluid temperature, and the other sensor is a heating element, maintaining a constant temperature difference higher than the fluid temperature, that is, when the gas flows through the heating element, the heat is taken away, and the heat is proportional to the flow rate of the gas and the density of the gas. To maintain a fixed temperature difference between the two temperature sensors requires the circuit to provide more power to the heating element, and the amount of output power in the circuit is related to the mass of the fluid, thus measuring the flow rate.

The reason why the thermal gas mass flowmeter is so popular is mainly due to its many advantages and wide application scenarios. Here’s a breakdown of why it’s popular:

Like the flue gas, this medium has a higher temperature, contains more impurities such as solid dust, the general application of large caliber, flow rate range is relatively wide, so the measurement is more difficult, so in the selection and use of flue gas flow timing should pay attention to the characteristics of the power plant flue wind speed, pay attention to the principle of choosing sensors, It is also necessary to pay attention to the wear resistance, corrosion resistance, dirt resistance and high temperature resistance of the sensor, and select the appropriate measurement position to ensure the measurement accuracy.

The thermal gas mass flowmeter uses the principle of thermal diffusion, and its working principle determines the change of the measured medium gas with the temperature and pressure, which affects the data change of the measured results.

Although the thermal gas mass flowmeter has many advantages in this respect, it can not be used for large pipe runoff measurement, pressure loss is relatively large, and the price is more expensive, which limits its measurement application in natural gas long distance pipeline.

The medium of one of the two tubes of the thermal gas mass flowmeter does not flow, and the medium of the other tube flows. By comparing the Coriolis force of two pipes to obtain the flow rate, it is convenient to eliminate the natural vibration of the pipeline, the vibration of the fluid itself and other factors that affect or interfere with the measurement.
