Liquid Level Controllers

Liquid level controllers are instruments which monitor liquid levels in vessels, and send out either pneumatic (typically 6 – 15 psig) or electric (e.g. 4 – 20mA) signals to either the main control system, a local control system, or directly to an automated control valve. 

CIRCOR Energy is a leading manufacturer of displacer style liquid level controllers available with both snap and throttling pneumatic pilots. These side mounted level controllers have been designed to endure harsh outdoor environments as well as high vibration applications such as compressors and pumps. 

For tightly regulated fugitive emission environments we offer our non-bleed snap acting pneumatic “Eco-Pilot” as well as our optional electric pilots.
