Fisherr L2e Electric Level Controller

The rugged Fisher L2e electric on-off level controller

uses a displacer type sensor to detect liquid level or the

interface of two liquids of different specific gravities.

This controller is ideal for controlling level in oil and

gas separators, treaters, and scrubbers. The reliability

of the L2e force balanced sensor design makes it well

suited for applications in the oil and natural gas

production, compression, and processing industries.

Features

n Repeatable Electric Level Control—In conjunction

with the Fisher easy-Drive™ electric actuator, a fully

electric level control loop is tunable for a wide

variety of applications (see figure 1).

n Effective Level Loop Tuning—Intuitive Zero and Span

adjustments allow flexibility in setting loop

performance over a level range of 5.0 to 559 mm

(0.2 to 22 inches).

n More Reliable Control—Premium quality

hermetically-sealed switch with gold contacts and

advanced knife-edge sensing provide highly

dependable and accurate liquid level control.

n On-Line Field Support—QR code on inside cover

gives instrument technicians instant access to

wiring, setup, calibration, tuning, and

trouble-shooting.

n Environmentally Responsible—Replacing a

conventional pneumatic level loop with fully electric

level control eliminates controller and dump valve

venting and requires less maintenance.

n Consumes No Electrical Power—Quality of design

and components help ensure no leakage current.

n Vibration Resistant Sensor Dynamics—Controller

performance and reliability does not degrade in

high vibration installations, such as on compressor

scrubbers.

LEVEL LOOP FIELD SUPPORT

n Field-Configurable Vertical or Horizontal

Displacer—Displacer may be adjusted in the field for

vertical or horizontal operation without additional

parts.

n Field Technician Friendly—The sensor can be easily

disassembled to inspect or replace process seals.

The controller, with no repairable or replaceable

parts, is easily replaced in the field.

n NACE Service Ready—Standard construction uses

materials that comply with the requirements of

NACE MR0175-2002.

n CL1500 Pressure Rating—Sensor assembly is

designed and specified for ASME B16.34 CL1500

service when using a Polyvinylchloride (PVC)

displacer. For PED (97/23/EC) maximum pressure is

limited to 200 bar (2900 psig).
