Abstract: Disclosed are a method and an apparatus capable of efficiently and precisely measuring a urinary flow rate by using a general purpose pressure sensor with a low price, instead of a conventional expensive weight sensor, even without a conventional funnel. According to the method and the apparatus, water pressure of urine accumulated in a vessel is transferred to an external pressure sensor through a pressure transfer pipe, the received water pressure is converted into electrical signals through the pressure sensor, the electrical signals are amplified through a bridge amplifier, the amplified analog signals into digital signals (water pressure signals), the water pressure signals are converted into volume signals through an interface with an analyzer, and urinary flow rate signals are acquired by differentiating the volume signals, in which the electrical signals are voltage signals corresponding to volume signals. An apparatus capable of measuring a urinary flow rate.
