Explanation: A manometer is a device used to measure the pressure of a liquid. It consists of a U-shaped tube filled with a liquid, with one end of the tube open to the atmosphere and the other end connected to the system being measured. The difference in the liquid level between the two ends of the tube is proportional to the pressure difference between the two points.
