Gauges are used for measuring magnitude or amount, such as the thickness of wire, the dimensions of a machined part, the amount of liquid in a container, steam pressure, capacity etc. A few types of gauges are air pressure gauges, oil pressure gauge and differential pressure gauges.
It is used as a reference for the setting of measuring equipment used in machine shops such as micrometers, sine bars, calipers, and dial indicators. gauge glass pin is similar to a gauge block. It is a precision ground cylindrical bar for use in Go/no go gauges or similar applications.
Gauge pressure is the pressure measured relative to the ambient atmospheric pressure.
A gauge measures the difference or gradient. A meter is a simple linear measurement and does not indicate necessarily indicate the gradient.
