Manometers

What are Manometers?
Manometers are devices used for measuring the pressure at a point in a fluid, by balancing the column of fluid by the same or another column of fluid.

Types of Manometers
Manometers are classified as:
  1. Simple manometers

    • Piezometer

    • U-tube manometer, and

    • Single column manometer

      • Vertical single column manometer

      • Inclined single column manometer

  2. Differential manometers

    • U-tube differential manometer

    • Inverted U-tube differential manometer


Advantages of Manometers
  • Easy to fabricate and relatively inexpensive
  • Good accuracy
  • High Sensitivity
  • Requires little maintenance
  • Suitable for low pressure and low differential pressure
