KTM100 RUS ®

Purpose – Metering of flare gas amount in atmosphere, continuous processes

Benefits:

  • Range of gas velocities from 0.03 до 120 m/s according to flare systems safe operation rules of Russian Federal Service for Ecological, Technological and Nuclear Supervision (Rostekhnadzor);
  • Metering at high temperatures to +330°C;
  • Cutting in and removal of sensors under operating pressure;
  • Simulation calibration method;
  • Operating pressure to 6.3 МPа – cut-in version;
  • Operating pressure to 25 МPа – base version;
  • Measurement error of the single-beam version is ±1.5-5%, two-beam version, ±1-3%;
  • Installation of the Ex d computing device at the primary sensors installation site;
  • Remote indication and control module, length from the installation point – 1000 m;
  • Self-check of beams contamination and the flow meter general state;
  • Calculation of gas mass flow rate without a density meter by “Hydrocarbon” method;
  • Service life – 15 years.
