​The Erosion sensor has been designed to the highest industry standards to provide customers with dependable and accurate measurement of metal loss through erosion within a high integrity mechanical package. Teledyne Marine can provide in-house turnkey systems including sensor, cable and interconnect. 

The Corrosion sensor utilizes Teledyne Marine's proprietary CEION® technology to provide extremely high accuracy metal loss detection. This high accuracy data is output in real time in engineering units simplifying system integration. The sensor uses a flexible communications interface with outputs over either CANbus (CiA443, SIIS Level 2) or MODbus (RS485).

Information on total metal loss can also play a key part in operating risk reduction and reducing loss of containment incidents in subsea environments.

Key Features:

  • Dependable and accurate measurement of metal loss through erosion, with a high integrity mechanical package
  • All configurations of the sensor are rated to 15 KSI at the maximum operating temperature.
  • The design of the unit includes dual redundant penetrators between process fluid and seawater.​
  • Real-time data available from instrument in engineering units

Benefits:

  • ​Combined with the pressure balanced nature of the sensor design, the unit provides a safe, high reliability package where operators and users can be assured of high integrity data with a design life of >25 years.​
  • The real-time nature of the metal loss data from this sensor provides operators with accurate information on the mechanical erosion occurring within subsea production equipment. This information will form an integral part of any Sand Management Strategy and provide more confidence to operators when running facilities at the maximum acceptable sand rate.
