How is the manometer used to measure pressure?

　　How does the air manometer work and what is the principle of the air manometer? How is the Air manometer used to measure pressure?

　　The work of the Air manometer is based on the principle of hydrostatic balance. The main reason is that the pressure gauge has a liquid storage tank, which contains liquid. The source will be connected to the reservoir so that the pressure can be measured. The reservoir will be connected to a column that will be exposed to atmospheric pressure. The pressure gauge can have a sealed or unsealed column, and the gauge pressure can be measured by using an open column pressure gauge. Absolute pressure can be measured using sealed column pressure gauges, which can also be used to measure vacuum.

　　If we connect the Air manometer to a process, the liquid level of the tower will change, and these changes will depend on the pressure source to be measured. We need to know the type of liquid in the tower, according to the type of liquid used, it can increase or decrease according to the pressure, and also know the specific gravity, in order to measure correctly.

　　What types of air manometers are there?

　　Classification of pressure gauges

　　Pressure gauges can be divided into simple pressure gauges and differential pressure gauges.

　　Simple pressure gauge

　　This type of pressure gauge can measure the fluid pressure at a certain point in the pipeline. Simple pressure gauge types include pressure gauges, U-tube pressure gauges, and single-column pressure gauges.

　　Differential pressure gauge

　　This type of pressure gauge measures the pressure difference between two points. Differential pressure gauges include U-tube differential pressure gauges and inverted U-tube differential pressure gauges.

　　pressure gauge

　　The pressure gauge is a simple pressure gauge used to measure the pressure of the liquid in the pipeline. The device has a vertical tube and its operation is based on the principle of hydrostatic balance. One end of the glass tube of the device will be connected to the point where the pressure is to be measured, and the other end will be open to the atmosphere. The pressure rise will depend on the pressure at that point, and this pressure can be measured by the height of the liquid in the tube.
