ABSTRACT:
A selectively energizable flow meter system comprising a valve having at least one fluid inlet port for receiving fluid under pressure and a plurality of fluid distribution ports and including a valve element selectively movable to direct liquid to predetermined fluid distribution ports, a metering device, and valve element positioning mechanism connected to the valve element. The valve element positioning mechanism is operable upon energization of the system to establish fluid flow communication between the metering device and at least one valve fluid distribution port and responsive to de-energization of the system to direct pressurized fluid entering the valve fluid inlet port to a valve fluid distribution port bypassing the metering device.
