Ultrasonic Flow Meter KTM700 RUS ®
Commercial metering of natural gas, oil-dissolved gas and hydrogen
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.
