Gas meters KTM100H M LB are designed for measurement and calculation of volumetric flow rate, gas volume under operating and standard conditions, mass flow rate, molar mass of various non-aggressive and aggressive gases and vapour, including natural, associated petroleum and flare gases in the single-phase parameter range. Description of measuring instrument.
Gas meters KTM100H M LB work on the principle of measuring the difference of ultrasonic pulse transit time. Transceiver units are installed on both sides of the channel/pipeline at a certain angle to the gas flow.
The transceiver units have piezoelectric ultrasonic transducers that work alternately as a receiver and transmitter. The sound pulses are sent at an angle to the direction of the gas flow.
Depending on the angle and velocity of the gas flow, as a result of the effects of involvement and braking, different propagation times are observed for a particular direction of the sound pulses. The difference...
