ABSTRACT:
A flow transducer includes a piston movable in a sleeve to vary the area of an orifice. The piston may move in either direction from a position in which flow is prevented. Movement in both directions is opposed by a spring. The piston assumes a unique position for each flow rate and the position of the transducer is sensed to provide a signal indicative of low rate.
