Types of Pressure Measuring Devices-TS
Types of Pressure Measuring Devices Manometers Manometers are simple devices that measure pressure by balancing it against a column of liquid, typically mercury or water. The height of the liquid column in the manometer is directly proportional to the pressure being measured. These are classified as follows- Simple manometer Differential manometer Type of Simple Manometer There are several types of simple manometers commonly used for pressure measurement. Piezometer A piezometer is the simplest form of a manometer used to measure gauge pressure. It consists of a glass tube with one end connected to the point where pressure is to be measured while the other end is open to the atmosphere. The rise of liquid in the tube indicates the pressure at that Point. Single-Column Manometer A single-column manometer is a modified version of the U-tube manometer. It includes a shallow reservoir with a larger cross-sectional area compared to the tube. One end of the reservoir is connecte...
