Innage gauging tapes outage gauging tapes help oil exploration and production organizations in determining the amount of crude oil and petroleum products they have stockpiled. Innage gauging tapes comes with an innage plumb bob which is cylindrical shape and pointed at one end, similar to the shape of a bullet. The tip of the plumb bob reads as zero point. The purpose of innage oil gauge tape is to determine the depth of the stored liquid inside a storage tank. This tape measures the height of the liquid from bottom of the storage tank till the surface of liquid. The plumb bob has to touch the bottom of the storage tank.
