The Meriam Bellows D/Pline of instruments serves as a compliment to the Meriam Manometers by offering a choice when pressure rating, space, process compatibility and many other specifications are a factor. The Meriam Bellows D/P units are used by many instrument manufacturers as the basic differential pressure sensing devices for indicators, recorders, transmitters or controllers.
The Series 1226 Differential Pressure Indicating Switches are used for on-off control or alarm. They also indicate flow, liquid level or other process variables. These units are furnished with one or two SPDT type switches with actuation set points easily adjustable over most of the range of the instrument. The calibrated travel of the pointer is 270 degrees, which gives good differential pressure indication and switch resolution. Dials can be supplied with linear scales for differential pressure, square root scales for flow, or custom scales for level. The 1226 Series Switches are used extensively in power plants, compressor stations, and cryogenic applications. be supplied. The unit is compact and has 270° pointer movement for greater resolution.
