E-series for ESP
Electrical Submersible Pump Monitoring


Deploy our E-Series oil well monitoring systems for enhanced oil recovery and prolonged electrical submersible pump (ESP) runlife, enabling both well analysis and ESP surveillance using key parameters surrounding your motor and pump.

Multiple specifications enable an economical system to be deployed that suits your well; parameters can be hand-picked to measure the data that is valuable to your operation and options range from a simple 3-parameter to full 7-parameter system.

E-Series well monitoring systems are compatible with all ESP equipment and provide you with an independent source of well data for well analysis.

For low production wells with small economic impact we recommend measuring intake pressure and temperature to prevent pump-off protection and provide well pressure surveillance. 

For more prolific wells or wells with difficult operating conditions the addition of discharge pressure, motor winding temperature and vibration enable full well analysis to be undertaken to diagnose performance and optimise oil well production.


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
