FIELD: measurement technology, measurement of flow rate of dielectric liquids in pipe-lines. SUBSTANCE: device measuring flow rate of dielectric liquids includes pickup composed of dielectric case 1, flow and nonflow chambers 2, 3 which house electrodes 4, 5, 6 interconnected into two groups in each chamber and forming capacitors connected to differential inputs of two amplifiers 8, 9 and through diodes placed in forward direction to heterpolar outputs of pulse generator 7. Outputs of amplifiers are connected to differential inputs of third amplifier 10 which output is connected to conversion and information output unit 11. EFFECT: expanded dynamic range and increased sensitivity of device. 1 dwg |
