Our range of manometers is extensively used in various industrial applications for pressure and vacuum measurements. These are also used for flow measurement techniques. The manometers we offer are available in wall-mounting or pedestal type and ''U'' tube or single limb type. They can either be of an inclined type or can be provided with a vernier scale for obtaining greater accuracy. The normal accurateness of the manometer is 1 mm but with an inclined tube of 0.1 mm, better accuracy can be obtained. A changeable vernier can provide a readability of 0.1 mm.
Types of manometers:
Single Limb Manometers-These single limb manometers are provided with a well which has a much larger area to that of the manometer tube and the level variation in the well is negligible to the rise in level in the Manometer tube. The scales of these manometers are also equipped in such a way as to compensate the level change in the well. Multi tube manometers with individual wells find application for multiple reading of pressure and also appropriate for tank level gauging with purge tube.
''U'' Tube Manometer-The standard ''U'' tube type manometers we offer consist of two straight glass tubes with a ''U'' bend at the bottom end. Our range of manometers is provided with top and bottom blocks that are fitted with accessories such as external zero adjuster valve, safety cover, filling and drain plugs, catch pots, zero leak ball check valves, zero adjustable scales, vernier scale, levelling screws, swivelling body and others.
Connection: 1/8" / ¼" / ½"; BSP, NPT, Ferrule or hose connector.
To prevent the fluid from leaving the manometer check valves are used if the instrument is operated beyond the range. Return wells are also used to prevent loss of the representative fluid by collecting the over flow fluid and returning it to the manometer.
