ESP Downhole Choke and Sensor Module (Gauge) Pressure Measurement
The intake pressure measures the pressure inside the motor housing. Motor oil protects
the intake pressure port from well fluid contamination.
The discharge pressure measures the pressure at the pump discharge port via a
hydraulic line connection to the discharge port on the pump. This connection is available
only on Dual Pressure gauges such as the ESP-3500 and QESP-3500.
