Dwyer Aluminum Electric Gas Mass Flow Meter, for Industrial

Listing ID #5368432

Gas Mass Flow Meter

series gfm2 gas mass flow meter

±1% fs, programmable relays

the series gfm2 gas mass flow meter is an ideal choice for the measurement of flow rates of a wide variety of gases. Unit can be calibrated for a variety of gases with user selectable 0 to 5 vdc or 4 to 20 ma and two relay outputs and programmable totalizer that indicates total gas quantity.

product applications

gas flow measurement

gas glow control

operating pumps and valves

process equipment

vacuum processes

glass and metal coating

film deposition
