E-series for ESP
Electrical Submersible Pump Monitoring

Customised monitoring to suit your operational requirements

The Zenith E-Series sensor is available in multiple specifications to suit the application and economic impact of deploying a monitoring system on your ESP. Parameters can be customised at point of order to provide a level of monitoring to suit your operational and economic requirements.

Maximise runlife while reducing costs

Automatic alarm and trip feature safeguards your ESP and well preventing unnecessary workovers and minimising expenditure, protecting against:

• Motor overheating
• Excessive well draw-down
• High or low flow rates (pump upthrust or downthrust)
• Dead heading or shut in
• Resonant vibration frequencies

Optimise production

• Dual pressure option enables full validation and analysis of well and ESP operating conditions
• Feedback intake pressure level to your VSD frequency setting to provide automated control of draw-down
• Fast sampling and accurate sensors enable analysis of draw-down and build-up pressure transients

Independent source of data for analysis

• Identification of pump wear issues
• Validation of inflow/outflow data
