Description
Pressure gauges measure a force applied by a liquid or gas to a surface.

Recently, the University’s ventilation units were tested using a pressure gauge, which along with the fan speed, was used to calculate their operating airflow. This allowed the University to calculate safe room capacities.

This type of pressure gauge was widely used because it was very sensitive and accurate. It was designed for industrial processes, such as on steam engines and boilers.
