KTM700 RUS ®
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
