Explosion-proof argon/nitrogen/natural gas mass flow meter

Explosion-proof argon/nitrogen/natural gas mass flow meter are specially designed for small pipe flow monitoring and control. The series can measure gas flow in a pipe diameter as small as 3 mm,but not over 19 mm. With the self-flow conditioning feature of the MEMS sensor package, the meters feature an extremely low pressure loss compared to the traditional by-pass thermal mass flow meters in this application scope. The accuracy of the meters are generally ±(1.5+0.2FS)% or better depending on the requests. The meters can work at an environment of -20 to 60 C and pressure up to 1.5 MPa. Applications include semiconductor gas process monitoring and control, hospital oxygen gas monitoring, etc.
