Pneumatic Level Controller
Pneumatic Level Controllers are field-reversible between snap and throttle level control, also field-reversible between direct and indirect pilot output signal.
These controllers are great for interfacing (sensing and holding a level between two different specific gravity liquids in a vessel). Several different displacer options available to handle an array of different possible conditions: small differential liquid specific gravities, high temperature, corrosion, large span, small tank diameters, and small access openings.
