Electric on-off level controller for production and processing

Emerson Automation Solutionsvisit website


The Fisher L2e level controller brings fully electric level control to a wide variety of applications in production and processing systems, using a rugged force-balanced displacer sensor to detect the level of a single liquid or the interface of two liquids. The controller’s new advanced knife-edge sensing design combines with aerospace-quality switch technology to provide rugged, reliable and accurate level control.

A fully electric level control loop, consisting of the L2e level controller used in conjunction with a Fisher easy-Drive electric actuator powered D3 or D4 control valve, helps to eliminate emissions and increase uptime, and requires less maintenance than conventional pneumatic level loops. The L2e zero and span adjustments enable tuning for a wide variety of level loop applications. In addition, the controller is certified for use in hazardous areas and is NACE compliant for sour service.

By scanning the QR code on the inside cover of the L2e, instrument technicians have access to 24/7 field support for set-up, calibration and loop tuning. Visit for more information or contact your Emerson sales office and ask to see the L2e Electric Level Controller product bulletin (pdf, 135kB).
