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. |
