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 1126P-2 is designed for portable applications. Typical examples are periodic measurements of the pressure drop across filters, balancing of flow rates in heating and cooling systems, and checking of backflow prevention devices. Meriam’s 1126P-2 consists of an 1126 D/P Indicator with 3-valve manifold and piping, 2 hoses, and quick disconnects. Each instrument system is assembled as a complete package with all the accessories mounted in a rugged, lightweight, case. When used as a flow measuring device, the instrument normally comes with a 0-100% square root scale. With all flow elements designed for the same differential, multiplying the scale reading by the primary element’s full flow design value gives readings directly in flow units. Scales in flow units, inches of H20, PSI and metric units are also available.
