ABSTRACT:
A method and apparatus for measuring a dynamic flow rate of a bodily fluid in which the rate of flow is constantly changing includes an inlet to a chamber where flow accumulates. The accumulating fluid is in communication with the base of a sealed vertical column of air. An air pressure transducer in the upper portion of the column of air measures the pressure exerted upon the air by the accumulated fluid. The air pressure corresponds to the volume of accumulated fluid and is manipulated to yield a running indication of the flow rate. The chamber is automatically drained by a drainage conduit when the fluid reaches an upper operating level to reset the apparatus to a lower operating level to be ready to resume taking meaurements.
