Fisher™ FIELDVUE™ L2t Liquid Level Controller
Fisher FIELDVUE L2t liquid level controller
Fisher FIELDVUE L2t liquid level controller installed on an oil and water separator
The Fisher FIELDVUE L2t level controller is part of the rugged L2 series of liquid level controllers.
It uses a displacer type sensor to detect liquid level or the interface of two liquids of different specific gravities. This controller is ideal for level on gas separators and scrubber applications. The L2t design is an environmentally conscious solution with zero emissions.

Features

  • Improved Reliability
    • Moving to throttling control reduces equipment wear and creates smooth and continuous control by eliminating the full-stroke cycling associated with discrete control.
    • Use of the L2t reduces equipment inventory requirements as the level controller is adaptable for both throttling and on/off applications.
  • Factory Calibrated
    • The L2t controller is factory calibrated, simplifying setup.
    • Field upgrades to the L2t require no mechanical changes to vessels equipped with standard 2 NPT connections.
  • Environmentally Friendly
    • This zero-emission solution exceeds regulatory requirements and mitigates environmental concerns when used with electric actuation.
