A manometer is a pressure measuring device or gauge.
The word monometer is also used for a U-shaped tube partly filled with fluid. It utilized the surface area and weight of a column of liquid to both measure and indicate pressure.
A manometer is an instrument used to gauge and demonstrate pressure. There are two kinds of manometers, simple and computerized. The most fundamental and least difficult type of a simple is the U-Tube manometer, a glass or elastic cylinder twisted looking like a “U” where numbers are recorded and dispersed each inch on each side, and water is set in the middle of the twists of the “U”. Whenever pressure is applied, either emphatically or adversely, the water moves to demonstrate the strain behind it communicated in creeps of water section.
Creeps of the water segment are the most widely recognized type of estimation in the HVAC business while estimating static or gas pressure, albeit different units of measure are accessible and utilized around the world. Perhaps the most widely recognized simple sort is the Magnehelic check. These are observed commonly introduced by the maker of the framework with the goal that workers for hire can undoubtedly peruse the strain of the framework. Anyway, independent advanced manometers have turned into the new business standard with regards to estimating static strain. With a higher precision readout, discretionary double ports, extra boundaries, and readouts, by and large, they are a lot more straightforward to utilize.
How does Manometer work?
There are two ends of the manometer tube which is utilized to measure the pressure. One end is connected with a gas-tight seal and another end is left open to the atmosphere. The end which is subjected to the atmosphere experienced a pressure of 1 atm.
In the event that the test pressure is more than the reference pressing factor of 1 atm, the fluid in the test section is constrained down the segment. This makes the liquid in the reference segment ascend by an equivalent sum.
Types of manometer.
There are two types of manometer that can be classified further:
- Simple Manometers
- Piezometer
- U-tube manometer
- Single column manometer
- Differential Manometers
- U-tube differential manometer.
- Inverted U-tube differential manometer.
