FAQ’s

A thermal mass flow meter works on the principle and measures the flow rate of gas mass based on the convective heat transfer of a heated surface to the flowing fluid.

The mass flow meter is being pumped with fluid. The tube twists somewhat when there is mass flow. The arm that directs fluid away from the axis of rotation must provide force to the fluid in order to increase its angular momentum and cause it to bend backwards.

Yes, most mass flowmeters feature 0-5 VDC or 4-20 mA outputs. Connect a totalizer/monitor to a matching input to keep track of total accumulation ( 0-5 VDC or 4-20 mA).

As long as the mixture isn’t too intricate, this is possible. For pricing and availability of gas mixture calibrations, please contact our applications department.
