n: the distance from the gauge, or reference, point from the bottom of a tank to a gauge, or reference, point at the top of the tank, usually on the hatch. On marine vessels, the measurement must be made when the vessel is on even keel.

n: determining the liquid level of a tank so that its volume can be calculated. Usually done by lowering a weighted graduated steel tape through the tank roof and noting the level at which the oil surface cuts the tape when the weight gently touches the tank bottom. It can also be done by measuring the distance between liquid height and a reference point and subtracting the distance from the gauge height to determine liquid height.

n: a measure of the volume of liquid in a storage tank determined by measuring from a reference point at the top of the tank to the surface of the liquid in the tank and subtracting that measurement from the gauge height of the tank. Used when direct measurement of the liquid level is not possible. Also called ullage gauge.

n: the vertical distance from the bottom of the tank or datum plate to the reference point on the hatch;nonnally engraved on or near the reference point.

n: the obtaining of several measurements, such as ring circumference, gauge height, and tank height, to determine how much a tank will hold.
