Abstract
A device for measuring the velocity of flow of a liquid comprises electrodes over which the liquid flows. A chemical emitting electrode is mounted so as to contact the liquid at a first point and is supplied with periodic input pulses by a current pulse generator such that chemicals are caused to be periodically generated on its surfaces. A second chemical detecting electrode is mounted downstream of the first point. The second electrode is connected to a potentiostatic circuit which produces an output signal when it detects the arrival of chemicals produced by the first electrode. A circuit measures the time between an input pulse and the corresponding output signal such that the velocity of the flow of the liquid can be determined.
