Description of 4 ~ 20 MA RS485 Pulse Nitrogen Gas Flow Meter
Llabtory Inline Along Digital Tester
4-20mA nitrogen 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
4-20mA nitrogen gas mass flow meter feature an extremely low
pressure loss compared to the traditional by-pass thermal mass flow
meters in this application scope. The accuracy of the 4-20mA
nitrogen gas mass flow meter are generally ±(1.5+0.2FS)% or better
depending on the requests. The 4-20mA nitrogen gas mass flow meter
can work at an environment of -20 to 60 C and pressure up to
1.5
