Zusammenfassung: | FIELD: measurement of flow rate of gas, oil, water and other liquids flowing through pipe-line. SUBSTANCE: the device has a flow body installed in the measuring pipe-line and made in the form of a wing-shaped section or plate, and connected to a force cell, having a frequency output signal, throng a spring-loaded power-transmitting member. The force cell is series-connected to a frequency divider, coincidence pulse separation circuit, pulse counter, register and recorder. The counter is connected to a phase-lock loop unit of pulses of preset duration, connected to a pulse shaper. EFFECT: enhanced reliability due to the absence of movable and vibrating parts. 4 cl, 2 dwg |
