ABSTRACT:
A method and apparatus for measuring the volume of a fluid using a load cell transducer in which the container holding the fluid, such as a cardiotomy reservoir, is firmly but detachably engaged to an adapter for a load cell transducer. Further, this invention relates to a method and apparatus for detecting the presence and alignment of the container on a load cell so as to allow accurate measurement of the volume of a fluid contained within the container. The apparatus generally includes a magnetic ring on a bottom-facing surface of the container, a metallic ring on an upward-facing surface of the mounting adapter for the load cell and a sensor capable of detecting a magnetic field.
