ABSTRACT:
A positive displacement, reciprocating fluid flow meter produces a digital electrical output signal. The meter includes a piston which reciprocates within a cylinder for accurately measuring fuel flow rates over a wide range of rates. The device is particularly useful in measuring the rate of flow of fuel to an engine, and incorporates a valve for bypassing the piston to permit resetting of the meter at the end of each piston stroke.
