VA Flow Meter for acidic chemicals, high temp. and pressure

  • SGMVAPVCGas and liquid flow - VA float principle
  • stainless steel VA w. PTFE lining or fully PP/PVC
  • Low Pressure Loss
  • Indication via Magnetic Coupling
  • Individually calibrated - medium specific scale
  • Accuracy: ±1.6%


The SGM gas and liquid flow meter series from Kirchner works on the variable area float principle. It provides instantaneous values for gas and liquid flow monitoring in pipelines with high temperature, pressure and highly acidic chemical liquids with low pressure loss. Since the vertical position of the float is transmitted magnetically to a dial gauge, the SGM, as opposed to standard type variable area flow meters with a glass tube, is also suitable for measuring the flow of opaque media.
