ABSTRACT:
A pump differential pressure monitor system enables both discharge and intake pressure to be monitored at the surface of a centrifugal well pump. This system includes a tubular sub mounted between the pump and the tubing. A receptacle is located inside the sub. A bypass passage extends past the receptacle for directing fluid discharged from the pump past the receptacle and into the tubing. A pair of pressure sensors are lowered on conductor cable and located inside the receptacle. One of the sensors communicates with the bypass passage to monitor discharge pressure. A port extends from the receptacle to the exterior of the sub and communicates fluid to the other pressure sensor for monitoring intake pressure.
