The U Tube Manometer, have "U" shaped tube, half filled with liquid (Water / Mercury / SP Gr. 0.81). When both the tubes are open, the liquid is at the same height in each leg (Tube / Limbs). When positive pressure is applied to one leg the liquid is forced down in that leg and up in the other. The difference in the height, which is the sum of the reading above and below zero, tells you the pressure. When vacuum is applied to one leg, the liquid rises in that leg and falls in the other. The difference in the height indicates the amount of vacuum.

The U Tube Manometer, consisting of two Glass Limbs. Stainless Steel / Brass Connecting fittings mounted on a metallic frame, provided with White Acrylic Scale with zero at the center. The U Tube Liquid Column Manometer we provide is used to determine Velocity and Static Pressure, Leakage, Fan Efficiency and Gas Pressure. The Manometer will be protected with transparent acrylic front cover fix with Aluminum frame and external zero adjustment Knob / Drain Plug / Fill Plug will Be Provided.
