KTM700 RUS ®

Benefits:

  • Operating pressure (excess) to 45 МPа at turned solid design;
  • Turned solid versions to DN1400;
  • Metering of hydrogen H2 and pure gases;
  • Metering of fume-laden and humid gases, gases with high content of mechanical impurities (UGS);
  • Metering of corrosive gases (made from designated stainless steels: Monel*, Hastelloy** and other at customer’s request);
  • Compensation of housing geometric dimesions change by temperature and pressure;
  • Measurement error to ± 0.5%;
  • Simulation calibration period ±0.7%;
  • Calculation of gas mass flow rate without a density meter by “Hydrocarbon” method;
  • Separate calculation for the Customer and the Consumer with two independent meters in one housing (Quadro version);
  • CMC;
  • Possibility of sensors replacement under operating pressure;
  • Service life – 20 years.
