Description

GFM mass flow meter

A low cost solution to thermal mass flow metering for gases is presented by Aalborg in introducing the model GFM mass flow meter line.

The GFM design combines the convenience and accuracy of conventional mass flow devices with low costs previously unattainable. Each of these meters incorporate an advanced “U”-shape tube sensor in conjunction with flow passage elements constructed of aluminum and brass for non-corrosive gases or 316 stainless steel for corrosive applications.

 

Design Features

  • ± 1% FS accuracy is standard
  • rigid metallic construction
  • available flow ranges starting from 0 to 10 sccm up to 0 to 1000 slpm
  • maximum pressure of 1000 psig (70 bars)
  • leak integrity 1 x 10-9 sccs of helium
  • NIST traceable certification
  • built-in tiltable LCD readout (some models)
  • 0-5 Vdc and 4-20 mA signals
  • circuit protection
  • can be used as a portable device
  • engineering units or 0 to 100% displays
  • totalizer option
