Fisher 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 and compares the level with a desired value (set point) to produce a pneumatic signal that can operate a dump valve. 

This controller is ideal for controlling level on gas separators and scrubbers.

The L2 pneumatic level controller offers snap-acting or throttling control and features a low-bleed relay to help to conserve natural gas to reduce emissions. 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.
