Abstract
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.
