U Tube Manometer :U-tube Manometer Principle - Inst ToolsA U-tube manometer is a device used to measure pressure differences in a fluid, such as gas or liquid. It consists of a U-shaped tube filled with a liquid (like mercury or colored water), and pressure is measured by the difference in the liquid levels in the two arms of the tube. The pressure is calculated by balancing the pressure from the fluid against the pressure exerted by the liquid column, a difference that can indicate gauge pressu
