Thermal type gas mass flowmeter

Thermal type gas mass flowmeter is to use the principle of heat conduction 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, gas, flue gas, methane 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-flow meter, so that the most difficult large diameter, low velocity flow measurement becomes simple.

Features

• No pressure, temperature compensation, direct measurement of gas mass flow; 
• high repeatability, high reliability, high stability, high accuracy; 
• The maximum range can reach more than 1000: 1; 
• explosion-proof, corrosion-resistant design, suitable for harsh working conditions, erosive; 
• High sensitivity, especially for large diameter, low velocity flow measurement; 
• Minimal pressure loss is almost negligible; 
• varied structure, flexible installation, easy handling, easy to use, basic maintenance; 
• 4 ~ 20mA transmission output, relay, high and low alarm control output, RS485 communication output, and other variables output, intelligent control systems.

Applications

Can be used for mass flow in petroleum, chemical, power, water treatment, food, textile, pharmaceutical, electronics and environmental protection and other industrial sectors of air, hydrocarbon gases, flammable gas, flue gas and other gases or actual volumetric flow conditions measurement and monitoring.
