Mass calibrating system

Home > G/M Certification and Calibration > Mass calibrating system


 It is a system which measures and compares the volume of gas measured by standard meter with the volume of gas measured by flowmeter which is the object of calibration.


  • Standard meter: 3EA
    (G65 Rotary, G650 Turbine, G1000 Turbine)
  • Large barometer : 1EA
  • Electronic wireless thermometer and hygrometer : 1EA
  • Industrial resistance thermometer: 5EA
  • Pressure gauge: 5EA


  • Scope of calibration : 8 ㎥/h ~ 2 500 ㎥/h
  • Method of inhalation (blower)
  • It is possible to calibrate 2 same flowmeters at the same time.
  • System uncertainty: 0.27%
  • Automatic/semiautomatic/manual testings are possbile.
  • It is a rotating hydraulic system and is easy to install testmeters.
