Pneumomanometer

A pneumomanometer is a device for measuring the pressure of gases or vapors.

The word "pneumomanometer" is formed from two Greek words: "pneumo" - air, breathing and "manometer" - a device for measuring pressure.

Pneumomanometers are used to monitor pressure in various technological processes - for example, in the chemical industry, energy, and metallurgy. They allow you to determine the pressure of gas or steam in pipelines, tanks, boilers and other technological equipment.

The operating principle of a pneumomanometer is based on measuring the height of a column of liquid (most often water or mercury) displaced by gas pressure. Structurally, a pneumomanometer consists of a U-shaped tube filled with liquid, one arm of which is connected to a pressure source. Under the influence of this pressure, the liquid is partially displaced, and the pressure value is determined by the difference in liquid levels in the arms of the tube.

Modern pneumomanometers can have a digital indication of readings and an interface for connecting to an automatic monitoring and control system for the technological process.
