Manometer

Manometer; is an instrument used to measure the pressure of gas or liquid fluids. When connected to a closed system, it contains an indicator mechanism that is activated by the pressure exerted by the liquid or gas in the system. This movement is usually detected by a sensitive mechanism located on the inner surface of the manometer and can detect pressure changes. This detected change then causes an indicator or pointer to move, and this movement is presented as a pressure value on the indicator that the user can read.
