An apparatus and method for electronic measurement of urine volumes. The invention provides a device for establishing streams of uniform flow from a urine void by a user. The urine streams are passed by electrodes whereby resistivity changes in a current path between the electrodes indicates beginning and cessation of urine flow. Timing of the duration of the streams provides a measurement of urine volume per void.

An apparatus for measuring urine volume comprising: a pair of electrically isolated electrodes; means for collecting urine and conveying streams of urine past the isolated electrodes at a substantially constant rate of flow; and means for generating opposite polarity timing pulses associated, respectively, with increases and decreases in resistance between the electrodes associated with the beginning and the cessation of urine flow, including a source of alternating electrical potential connected to one of the isolated electrical terminals, a logarithmic signal generator coupled to a second one of the isolated electrical terminals, and a differentiating circuit coupled to receive signals from the logarithmic signal generator for generating the opposite polarity timing pulses indicating onset and cessation of urine flow through the outflow conduit; and a clock responsive to the timing pulses for determining the volume of the urine flow by timing their duration.
