Device for measurement of liquid flow rate with frequency output has measuring block that consists of two tightly separated cavities with openings that are connected to environment and place at one axis in horizontal plane, through fittings are connected to transformer by means of flexible tubes, filter, transformer of analog signal to frequency signal. Transformer has two-gate unipolar transistor, bipolar transistor, two capacitors, three resistors, inductance and source of direct voltage. |
