Downhole Measuring System TM01-18 product

Downhole Measuring System Triol ТМ01–18

Downhole Measuring System Triol TM01-18 is a high-temperature, reliable and profitable solution for systems working with hot fluids up to 175°C (347°F), where it’s necessary to collect, process, display and transfer actual parameters of the well and submersible equipment, with a pressure in the equipment suspension zone up to 40 MPa (5800psi).

Investment Savings – Cost savings during commissioning and well operation – Increased production through quality and timely solutions – Increased service life of submersible equipment – Ensuring the safety of personnel at wells site.

  • pump discharge pressure
  • pump discharge temperature
  • submersible motor oil temperature or the temperature of the motor stator winding
  • ESM vibration acceleration in the X, Y and Z axis
  • insulation resistance in the circuit “Step-up transformer – submersible cable – ESM”
