Thermal gas mass flowmeter is the use of heat conduction principle side of fluid flow meter. The meter constant temperature difference method for accurate measurement of gas mass flow. Measurable pipeline flowing air, nitrogen, hydrogen, oxygen, chlorine, gas, gas, flue gas, biogas and other gases mass flow monitoring instruments. Because of its diverse and flexible structure type, you can use the site to meet different needs. Especially in the plug-in flowmeter, so that the most difficult large diameter, low velocity flow measurement becomes simple. 
Features: 
Without pressure, temperature compensation, direct measurement of gas mass flow; 
High repeatability, high reliability, high stability, high accuracy; 
Turndown ratio can be up to 1000: 1; 
Explosion-proof, corrosion-resistant design, suitable for harsh working conditions, erosive; 
High sensitivity, especially for large diameter, low velocity flow measurement; 
The pressure loss is extremely small, almost negligible; 
Structurally diverse, flexible installation, easy handling, easy to use, basic maintenance; 
4 ~ 20mA transmission output, high relay, various variables low alarm control output, RS485 communication output, output, intelligent control systems.

Applications: 
Oil can be used for mass flow, Air, Power, Water treatment, food, textile, pharmaceutical, electronics and environmental protection and other industrial sectors, hydrocarbon gases, flammable gas, flue gas and other gases or actual volumetric flow conditions measurement and monitoring. 
Steel mills, coking plant boiler air flow measurement of gas flow, the secondary air flow measurement chimney flue gas flow measurement
