Title: Electrode resistance milk flow indicator - has resistance across electrodes dependent on flow in pipe to increase current at multivibrator
Inventor: HERTRICH UWE ING GRAD
IPC: G01F1/64
Filed: 1975-05-02
Abstract: The oscillator or multivibrator supplies a low- or high-frequency alternating current to a combination stage, in which the current (U1) which depends on the milk flow from the cow is produced on the series connections of the condenser (C1), the electrodes (E1, E2) and another condenser (C2). The milk flow is indicated on the electrodes (E1, E2) in the milk-pipe (3). The resistance figure between the two electrodes (E1, E2) determines the amount of current (U1). The combination stage also incorporates a compensating resistance (R) and a coupling condenser (C3). Should the milk flow in the pipe (3) decrease during milking, the resistance between the electrodes increases, and the current (U1) increases.
