Technology / Vent Reduction / Fisher L2 and L2sj Liquid Level Controller

Fisher L2 and L2sj liquid level controllers use a displacer-type sensor to detect liquid level or the interface of two liquids of different specific gravities.

The reliability of the design makes these controllers well-suited for high pressure liquid level applications in natural gas production, compression, and processing.

Features

  • Two-stage proportional relay with integral action provides more dependable liquid level control.
  • O-ring friction and process pressure sensitivity are minimal. Performance stays constant with process pressure changes and controller remains vibration-resistant.
  • The displacer may be adjusted in the field for vertical or horizontal operation without additional parts.
  • The controller can be adjusted in the field for direct or reverse action without additional parts.
  • Sensor assembly is designed and specified for ASME B16.34 CL1500 service when using a Polyvinylchloride (PVC) displacer.
  • The ability to pipe away exhaust permits using natural gas as the operating medium.
  • Both the controller and the sensor can be easily disassembled to inspect the process seals and for maintenance.
