Ultrasonic Flow Meter KTM600 RUS ®
Technical metering of natural gas, oil-dissolved gas and other gas media and mixtures
Benefits:
- Operating pressure (excess) to 55 МPа at turned solid design;
- Stainless steel, Monel* or Hastelloy** versions;
- Metering of hydrogen H2 and pure gases;
- Metering of fume-laden and humid gases, hydrates and gases with high content of mechanical impurities;
- Metering of cryogenic media to -194°C;
- Turned solid versions to DN1400;
- Measurement error to ± 0.5-1.5 %;
- Calculation of gas mass flow rate without a density meter by “Hydrocarbon” method;
- Sensors replacement under operating pressure;
- Service life – 15 years.
