Abstract
A gas pressure driven fluid pump having an electronic cycle counter. The pump has a pump tank with a liquid inlet and a liquid outlet. A switching mechanism is operative within the pump tank for switching to exhaust porting when the fluid level within the pump tank falls to a low level position and switching to motive porting when the fluid level within the pump tank rises to a high level position. An electrical counter circuit is operatively connected to the pump tank for incrementing a stored count in response to the fluid level within the pump tank rising to a predetermined level.
