Ultrasonic Level Meters
Flange type thermal mass flow meter
My company produced one order for flange connection thermal mass flow meter.
The connection is DN2'' ANSI 150# flange.
And customer will use this flow meter to measure nitrogen gas.
It could display standard flow rate directly.
Thermal mass flow meter is good at measuring kinds of air and gas, except steam and acetylene.
It has 1% accuracy and high stability.
