L2 Liquid Level Controller

The rugged Fisher L2 liquid 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 on gas

separators and scrubbers. The reliability of the L2

design makes it well suited for liquid level applications

in natural gas production, compression, and

processing. The device delivers a pneumatic output

signal to a control/dump valve. The sensor uses a

threaded 2 NPT or an NPS 2 CL150 through 1500

slip-on flange connection to the vessel.

Features

n More Reliable Control—Two-stage proportional

relay with integral action provides more dependable

liquid level control.

n Snap-Acting or Throttling Control—One standard

controller available as either throttling or

snap-acting.

n Vibration Resistant Sensor Dynamics— O-ring

friction and process pressure sensitivity are

minimal. Performance stays constant with process

pressure changes and controller remains vibration

resistant.

n NACE Service Ready—Standard construction uses

materials that comply with the requirements of

NACE MR0175-2002.

n Field-Configurable Vertical or Horizontal

Displacer—Displacer may be adjusted in the field for

vertical or horizontal operation without additional

parts.

n Field-Reversible Output—The controller can be

adjusted in the field for direct or reverse action

without additional parts. The controller also has

adjustable gain sensitivity.

W8418-1

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).

n Vent-Away Case—The ability to pipe away exhaust

permits using natural gas as the operating medium.

n Easy Maintenance—Both the controller and the

sensor can be easily disassembled to inspect the

process seals and for maintenance.
