Abstract
To measure liquid flow through channels with various cross sections, detectors of liquid level and velocity are placed in proximity to the liquid to measure flow in terms of the product of the cross sectional area of the fluid and its velocity. Adjustable switches are employed to provide input signals to the computation circuitry which are constants while the detectors provide the data signals which result from the dynamic measurements.
