Electric Submersible Pump (ESP) Working Monitor System is composed of downhole?instruments and Surface equipments (Surface host computer and choke), applied to monitor downhole parameters (pressure, temperature, vibration, and Current Leakage), at the same time it transfers the parameters to surface equipment. ?The processed data by surface equipment has special reference to the engineer and operator’s adjustment of parameters，to management?and decision-making?of producing well, ?accordingly improving oilfield’s production?and management level .

Pressure?measurement of intake and discharge.

Temperature measurement of intake and motor.

Motor vibration measurement (X-axis, Y-axis, Z-axis).

Current Leakage?measurement.

All real-time data can be displayed?and record by surface host computer.

Ability of interface and communication?with other surface equipments（such as frequency converters）.

Download storage data through USB.
