What is an industrial barometer or manometer?

Industrial manometer or industrial barometer is a device used to measure and measure pressure. Manometers have special applications in industry. Industrial manometers are usually installed where the pressure must be read and the pressure is read by the operator.
Manometers are widely used in industries such as oil, gas, petrochemical, refineries, steel, power plants and so on. And in most industrial processes, the pressure must be constantly monitored, otherwise it causes irreparable damage such as failure of part or the whole system, damage to the operator, product failure, fire and explosion, and so on.

We will first introduce the pressure, its types and units of pressure measurement, then we will introduce the types of manometers and their applications and how to choose a manometer.
