Meriam's multiple tube well type manometer, is a versatile instrument used in production testing, process measurement, and for laboratory data analysis. Up to six individual direct reading manometer systems are enclosed in individual compact cases. Each tube (system) can be used to measure pressure, vacuum, differential pressure, flow or liquid level. Complex pressure distributions or multiple pressure relationships are easily observed and readily compared. Different manometer fluids of various densities can be used in each tube.

The scales can be graduated as required. Flexibility for various application requirements is possible by design modifications. For example, raised wells can be furnished so positive and negative pressures can be indicated without changing the pressure connections. The multiple tube type manometer is widely used for tank liquid level measurement.  Many tanks located remotely on a tank farm are connected to the level gauges in the central control instrument panel. Special scales can be graduated duplex to indicate tank liquid depth in feet and inches, as well as tank capacity in gallons or pounds.

Model 33KBX35 Construction
The indicating tubes are ruggedly housed in individual aluminum channels which are securely connected together. The end blocks are constructed of stainless steel. Each manometer has a large bore glass indicating tube (securely
packed with leakproof seals) to give a bold, easy-to-read indicating  column with any manometer fluid. Stainless steel fluid wells of large cross sectional area are fabricated to close dimensional tolerances. Individual measuring scales, with sharp black graduations on a non-glare white satin background, extend on both sides of the indicating column. Large numerals at both ends of major graduations provide at-a-glance readability. Individual scale adjustment for zero reference is conveniently made on each tube of the instrument. The framed window provides protection from dirt and moisture. Each tube has the Meriam Stream-Flow drain valve to facilitate draining. The instrument finish is a durable black textured urethane. In addition to the table mounting (TM) style shown here, wall mounting (WM)and flush front mounting (FF) styles are also available.
