China Thermal gas mass flowmeter products is an instrument for measuring fluid flow based on the principle of heat conduction. The instrument uses the constant temperature difference method to accurately measure the gas mass flow. China Thermal gas mass flowmeter products has the advantages of small volume, high digitization, convenient installation and accurate measurement.

Technical advantages of china thermal gas mass flowmeter products:

1. Proprietary traffic data model algorithm; Fuzzy theory control temperature and humidity algorithm;

2. High performance intelligent microprocessor and analog-to-digital and digital to analog conversion chip;

3. Wide range ratio 1000:1; Large diameter, low flow velocity and negligible pressure loss;

4. Direct measurement of mass flow without temperature and pressure compensation;

5. Low flow rate measurement is very sensitive;

6. Convenient design and selection, easy installation and use;

7. Suitable for all kinds of single or mixed gas flow measurement.
Advantages of china thermal gas mass flowmeter products:

• the real mass flowmeter can measure the gas flow without temperature and pressure compensation, which is convenient and accurate. The mass flow or standard volume flow of gas can be obtained.

• wide range ratio, can measure gas with flow rate up to 100nm / s and bottom to 0.5nm/s, and can be used for gas leak detection.

• good seismic performance and long service life. The sensor has no moving parts and pressure sensing parts, and is not affected by vibration on the measurement accuracy.

• easy installation and maintenance. If the site conditions permit, the installation and maintenance without shutdown can be realized. (special customization required)

• digital design. Overall digital circuit measurement, accurate measurement and convenient maintenance.

• adopt RS-485 communication or HART communication to realize factory automation and integration.
Disadvantages of thermal gas mass flowmeter:

1. The response of china thermal mass flowmeter products is slow.

2. In places where the measured gas composition changes greatly, the measured value will change greatly due to the change of CP value and thermal conductivity.

3. For small flow, the instrument will bring considerable heat to the measured gas.

4. For the thermal distributed thermal gas mass flowmeter, if the measured gas deposits scale on the pipe wall to affect the measured value, it must be cleaned regularly; It has the disadvantage of easy blockage for thin tube instruments, which can not be used under normal circumstances.

5. The use of pulsating flow will be limited.

6. The use of thermal mass flowmeter for liquid is also limited for viscous liquid.
