Abstract
The reciprocating piston positive displacement flow meter of the present invention comprises a hollow flow tube having a movable piston for reciprocal movement between opposite ends and a solenoid controlled valve assembly having a sliding valve member for reversing the direction of fluid flow through the flow tube in response to the activation and deactivation of a solenoid. The solenoid is switched from an activated state at one end of the piston stroke to an unactivated state at the opposite end.
