A urine discharge measuring system for medical use which includes a gimbal mounted frame supporting a urine container of fixed dimensions to collect urine from a urinary catheter attached to a patient. An ultrasonic transceiver mounted above the container and operated in conjunction with a microprocessor based control unit, positioned adjacent to the transceiver, periodically and automatically measures the height of the urine collected within the container. The measured fluid height is converted to fluid volume by the control unit. To maintain the sterility of the container, the transceiver transducer(s) is mechanically isolated from the urine container by elements which allow the ultrasonic energy to be transmitted to and received from the interior of the container. In one described embodiment, desired measured volume accuracy is achieved by employing a reflective target within the urine container at a known fixed distance from the transceiver transducer. Comparison by the control unit of the measured distance with the actual distance to the target allows generation of corrections for variations of the speed of sound in air due to temperature and humidity to be applied when obtaining the urine height within the container. Digital displays in the control unit provide indication of past and present accumulation of the urinary output of the patient.
