Plug Sensor

Plug Sensor Introduction

Plug Sensor for monitoring of pipeline deposition or water breakthrough. Plug Sensor is practically a part of a Pipe Sensor and works identically to the Pipe sensor. The only limitation, when compared to the Pipe sensor, is that Plug Sensor measures locally, in the vicinity of the sensor. One or more sensors can be installed at strategic locations, such as wax or hydrates at points of high temperature gradients and scale, or asphaltene deposits at mixing points or pressure drops. When placed in a known location of the greatest deposition susceptibility, the cintinuous record provided by the sensor will also catch unexpected deposition events. In addition, the sensor can be placed in sections of pipeline that cannot be pigged, that remain susceptible to wax or hydrate blockage. The same sensor is also used to monitor water breakthrough of flow.

Plug Sensor is a part of the Pipe Sensor and can be applied in deposition monitoring as well as water breakthorugh monitoring.

Plug Sensor Features

  • A flanged connection – available in many pipe sizes and diameters.
  • Allows several types of deposits to be monitored (see Plug Sensor Applications & Services)
  • Easy to install and maintain without any moving parts
  • Without radioactive sources, safe to use and hassle-free fromregulations
  • No calibration needed – The system monitors right after powering up the system
  • For other information about the sensors, visit our FAQ page
  • The system components and cable lengths can be seen at Modular Design
  • See Beyond -compliant

One or more sensors can be installed at strategic locations, such as wax or hydrates at points of high temperature gradients and scale, or asphaltene deposits at mixing points or pressure drops. When placed in a known location of greatest deposition susceptibility, the continuous record provided by the sensor will also catch unexpected deposition events. In addition, the sensor can be placed in sections of pipe that cannot be pigged, that remain susceptible to wax or hydrate blockage.
