Pressure gauges are incredibly useful bits of equipment that can be used to monitor a variety of pressure-related measurements. A pressure gauge is an instrument used to measure pressure in various processes, including gas pressure, liquid pressure, and vacuum pressure.There are many different types of pressure gauges with different functionalities and applications. The most common types include the differential pressure gauge, the vacuum gauge, and the combined vacuum and pressure gauge. Let’s take a look at what each one does and how they can benefit your business.

Pressure gauges measure the pressure of a fluid and report it back to the user. They’re common in industrial settings where fluids need to be monitored, such as oil refineries and natural gas processing plants. In these settings, pressure gauges are often mounted on walls for easy visibility. Pressure is measured in various units including pounds per square inch (PSI), bars, and kilopascals (kPa).
Arithmetic is involved when reading a pressure gauge because it is an instrument that measures differential pressures. If you understand standard deviation, then you can read a pressure gauge. Many gauges have multiple needles that operate at different scales, so the readings need to be interpreted appropriately. The procedure for reading a pressure gauge is as follows:
