Subsea Flow Temperature Monitor


The ClampOn Subsea Flow Temperature Monitor is a non-intrusive instrument that calculates and monitors the temperature of the flow medium from outside the pipe.

Non-intrusive subsea sensor for flow monitoring

Some of the advantages of this sensor are: 

  • Non-intrusive
  • Retrofittable
  • Very long lifetime
  • ROV retrievable
  • Early detection
  • Safe operation – no impact on production
  • Can be used as add-on to sand/pig/vibration/CEM sensors

The sensor calculates flow temperature by measuring the pipe skin temperature underneath insulation and using algorithms to compensate for ambient temperature and the insulation coefficient.

On projects where the pipeline is not insulated, a section of pipe approximately 60 cm upstream and downstream of the sensor must be insulated to provide stable conditions around the sensor. The instrument communicates over RS485 Modbus, Canbus SIISL2, or      4-20mA.

The ClampOn Subsea Flow Temperature Monitor utilizes our well-established DSP subsea hardware platform. This platform has been in operation for more than 20 years and is built into more than 4.000 subsea sand monitors, pig detectors, leak monitors and vibration monitors installed worldwide.

The sensor is qualified to API17F 4th edition and ISO 13628-6, and rated TRL 7.
