Single Limb- Manometers Specification-:
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 prepared in such a manner as to compensate the level change in the well. Multi tube manometers with individual wells are used for multiple reading of pressure and also suitable for tank level gauging with purge tube.
'U' Tube Manometer
The standard 'U' tube type manometer has two straight glass tubes with a 'U' bend at the bottom end. These . manometers are provided with top and bottom blocks and fitted with such accessories like external zero adjuster valve, safety cover, filling and drain plugs, catch pots, zero leak ball check valves, zero adjustable scale, vernier scale, leveling screws, swiveling body, etc.
1/8" / ¼" / ½"; BSP, NPT, Ferrule or hose connector.
Maximum range 0-3000mm
Check Valve and Return Wells
Check valve is used to prevent the fluid from leaving the manometer if the instrument is operated beyond the range, either due to high range or surge conditions. Return wells are used to prevent loss of the indicating fluid by collecting the over flow fluid and returning it to the Manometer.
