U - TUBE MANOMETER

GAYATRI" make U-Tube Manometer are accurate, Simple and economical instruments for measurement of positive pressure, negative pressure, differential pressure, vacuum, flow etc. U-tube manometers indicates pressure as vertical distance from the top of the fluid in one leg to the top of fluid in the other leg. Scales are graduated from centre zero towards each end and distance s traveled by liquid from zero are added. There is no loss of accuracy if the two distances are different because of slight tube bore difference. The units of measure commonly used are mmW.g. inch W.g., mm Hg, Inch Hg, kg/cm 2, PSIG, mbar, Pa, Flow Units etc.
