HFM-205 Mass Flow Meter

HFM-205 Mass Flow Meter

Model HFM-205 can measure flow ranges from 0-1000 slm up to 0-2500 slm (N2 Equivalent); use elastomeric seals, provide analog outputs, and are constructed of stainless steel. The controller (HFC-207) has normally closed valves. Corrosive gases, with the exception of the halogens, pressures up to 1000 psig (optional) are easily measured.
