Bore gauge: a device used for measuring holes. Hole gauge [3] used to gage internal dimensions of bores that are either too small in diameter for an inside micrometer, and have greater economy than a bore gage or other precision internal gage. Caliper: a device used to measure the distance between two opposing sides of an object.
Gauge block, a metal or ceramic block of precisely known dimension, used in measuring; Sight glass, also known as a water gauge, for measuring liquid level heights in storage tanks and pressure vessels; Boost gauge, a gauge used in conjunction with turbo-super-chargers; Pressure gauge or vacuum gauge, see pressure measurement
A gauge block is a block of metal or ceramic with two opposing faces ground precisely flat and parallel, a precise distance apart. [31] The length of the path of light in vacuum during a time interval of 1/299,792,458 of a second is embodied in an artefact standard such as a gauge block; this gauge block is then a primary standard which can be ...
A particular choice of the scalar and vector potentials is a gauge (more precisely, gauge potential) and a scalar function ψ used to change the gauge is called a gauge function. [citation needed] The existence of arbitrary numbers of gauge functions ψ(r, t) corresponds to the U(1) gauge freedom of this theory. Gauge fixing can be done in many ...
The gauge is then removed and measured with the aid of a micrometer anvil heads, move the head of the gauge around while making the measurement to ensure you get the maximum reading. Grasp the gauge near the head to aid in your maneuvering of the gauge while adjusting the micrometer so it just stops the gauge's motion at one spot only.
A gauge theory is a type of theory in physics.The word gauge means a measurement, a thickness, an in-between distance (as in railroad tracks), or a resulting number of units per certain parameter (a number of loops in an inch of fabric or a number of lead balls in a pound of ammunition). [1]

A ring gauge, or ring gage, is a cylindrical ring of a thermally stable material, often steel, whose inside diameter is finished to gauge tolerance and is used for checking the external diameter of a cylindrical object. [1] Ring gauges are used for comparative gauging as well as for checking, calibrating, or setting of gauges or other standards ...
