  Purpose and field of application

ELEKTON-TMS-8 Telemetry system is designed for completions with Sucker rod pumping units (SRP), to record and transmit to external devices the current values of the following parameters:

  • formation fluid pressure at pump intake;
  • formation fluid temperature at pump intake;
  • insulation resistance.

In addition to the measured parameters, information about DHS status, type, measuring range is transmitted to the surface panel.

Digital signal is transmitted from the surface panel to the VSD through RS-485 port via Modbus RTU protocol. To the computer, the signal is transmitted via RS-232 interface.


  ELEKTON-TMS-8 Downhole Monitoring System Components:
  • surface panel ELEKTON-TMS-SP-8 or ELEKTON-TMS-SP-3 installed into the ELEKTON-05V VSD for progressive cavity pumping units, or into the ELEKTON-05SK VSD for sucker rod pumping units;
  • ELEKTON-TMS-DHS-8 downhole sensor installed at the bottom of submersible pump via an adapter assembly;
  • logging cable KG 1X0.75-20-130Oa for connection between between DHS and the surface panel.
