Apparatus For Measuring Volumetric Or Mass Fluid Flow

摘要

Apparatus and method are provided for accurately measuring the volumetric or mass fluid flow, especially when fluid flows in a non-continuous manner using a float. A preferred embodiment comprises a tube for accumulating liquid that is periodically drained and a float confirmed within the tube that floats on the accumulating liquid. The float has magnetic properties that can be sensed so as to measure the position of the float in the tube. A controller controls a valve provided in the bottom of the tube and opens the valve so as to allow drainage of the accumulated liquid according to the positioning of the float within the tube. The valve is opened when the position of the float is in a predetermined position within the tube so that the mass or volume of the drained liquid is known.
