The speed gauge is a wrist-watch like device that was created by Cisco Ramon to manage Barry Allen's speed output following the death of the Speed Force, as his speed became limited.


After the Speed Force died; due to infection by the Spectre's energy, Cisco Ramon devised the speed gauge to keep track of the level of intensity of velocity Barry Allen used, giving it to Barry to watch his speed output. Each color on the speed gauge represents how much speed Barry is using, with red being the most. All of Barry's speed abilities affect the colors on the speed gauge.[1]

Later, the speed gauge was used to measure how much speed the physical manifestation of the Speed Force was using.[2]
