PURPOSE:To measure a urine flow with high accuracy by fetching the amount of discharged urine as a voltage, bringing this voltage to an A/D conversion, and thereafter, inputting the result to a computer, and converting it directly to a flow rate data. CONSTITUTION:A urine flow is collected in a receiving tank 2 from a funnel 1, and its weight is converted to a voltage by a load cell 3. This voltage is amplified by an amplifier 4, and thereafter, converted to a digital signal by an A/D converter 13 and inputted to a computer 14. The computer 14 executes smoothing and differentiation of this data, and calculates directly a urine flow rate. As a result, a urine flow meter which can be adjusted easily, scarcely causes a change with the lapse of time, and also, has a high accuracy can be obtained.
