Thermal gas mas flow meters are measuring the mass flow or volume flow of gas,flow range can do 0.5Nm/s¡«100Nm/s. So this meter also can be used for gas leak detection.
Thermal meters require a fully developed flow profile as a prerequisite for correct flow measurement.
When the gas is very humid or saturated with water (e. g. Bio Gas), the piping and flowmeter body should be insulated to prevent water droplets condensing on the measuring sensor.
Flow range:1:100
Pressure up to 4.0Mpa
4-20mA is Optical isolation
Power supply:24VDC&220VAC
Response time:1S

Thermal mass flow meter is precision instruments that can directly measure mass flow,such as industrial gases, compressed gas, and other gases.
DC4-20mA four-wire output
Mass flow unit
Dual power:24VDC,220VAC
Min.Flow veloctiy:0.1Nm/s
Output:4-20mA

Thermal gas mass flowmeters are suitable for all industrial and test rig applications that demand quick and precise gas measurement. The flowmeters directly indicate the mass flow or normalized volume flow of gases without any additional pressure and temperature compensation. They have an impressively high accuracy, short response time and a very wide flow range with virtually no loss of accuracy even at the lowest flow rates.
