Fisher Types 1301F and 1301G regulators are self-operated, high-pressure regulators, which can be used where high pressure gas must be reduced for use as pilot supply pressure in pilot-operated regulators or as loading pressure in pressure-loaded regulators.
Fisher 2500 pneumatic level controllers provide rugged, dependable, and simply constructed pneumatic instrumentation for liquid level, interface level, and density service.
Fisher 249 caged level sensors provide more stable operation than do cageless sensors for vessels with internal obstructions or considerable internal turbulence.
Fisher 846 transducer converts an electrical output signal from a controller to a pneumatic signal necessary to operate a control valve actuator or pneumatic positioner.
Fisher C1 controllers and transmitters continue the tradition of durable and dependable Fisher pressure instrumentation, while addressing air/gas consumption concerns.
Fisher L2 and L2sj liquid level controllers use a displacer-type sensor to detect liquid level or the interface of two liquids of different specific gravities.
Fisher L2e electric on/off level controller uses a displacer-type sensor to detect liquid level or the interface of two liquids of different specific gravities.
