Abstract
In a metering pulse generator, a metering element engages a spring member to effect a gradual bending movement in one direction followed by a rapid return movement during which a pulse signal is developed by a piezoelectric material on the spring member . Energy is absorbed during each such rapid return movement of the spring member to provide damping, inhibit oscillations and effect reliable generation of a single pulse signal which is applied to an amplifier for transmission to a monitoring station.
