About product

Ultrasonic flow meter for custody gas transfer

Applications

  • Custody transfer of natural gas and associated petroleum gas
  • Custody transfer of hydrogen and hydrogen-injected natural gas
  • Measurement of regasified LNG at cryogenic temperatures
  • Custody transfer gas at distribution stations

Your benefit

  • Arrangement of measuring paths without reflection from the pipeline walls ensures long-term sta-bility, changes in the inner wall surface do not affect to the accuracy of the meter.
  • «Real-time Control» self-diagnostics system ensures on-time notification of an operator
  • High accuracy and reliability of measurements
  • Minimum requirements for the length of the inlet section of the measuring pipeline
  • Up to 3 weeks meter can operate without power supply
  • Built-in real-time performance monitoring (contamination, pulsation)
  • In situ verification without removal from the pipeline – once in 4 years
  • Service life – 15 years
