Fisher 2500 Pneumatic Level Controller

Fisher 2500Used in conjunction with the 249 series level sensors, the pneumatic 2500 level transmitter offers displacer style level control for your most demanding liquid level, interface level, or density service. 

Changes in level or specific gravity exert a buoyant force on a displacer, which rotates a torque tube shaft. The pneumatic level controller converts this rotational motion to a proportional pneumatic output connected to a dump valve.

Fisher pneumatic controllers are used wherever rugged, dependable, and simple constructed displacer-style pneumatic instrumentation is required in liquid level, interface level, or density service. The ruggedness of these products is demonstrated by their use in many kinds of demanding applications, including those in the power, chemical process, oil and gas production, and petrochemical industries.
