n: an instrument that automatically measures and displays liquid levels or ullages in one or more tanks continuously, periodically, or on demand.

n: a system that automatically measures and displays liquid levels or ullage in one or more vessel tanks on a continuous, periodic, or ondemand basis.

n: 1. a table that shows the capacities of, or volumes in, a tank for various liquid levels measured from the dip point or from the ullage reference point. Also called gauge or tank capacity table. 2. a table that is developed by recognised industry methods to represent volumes in each tank according to the liquid (image) or empty space (ullage) measured in the tank. Also called tank capacity table, tank table.

n: 1. a European term for the depth of liquid in a storage tank. 2. formation dip. See formation dip. iMage. ullage.

n: the angle at which the bed of formation slopes away from the horizon

the angle that the structural surface or bedding plane or fault surface makes with the horizontal. Measured perpendicular to the strike and in the vertical plane.

n: a European term for the depth of liquid in a tank. corresponding to a given ullage. It is obtained by subtracting the observed ullage from the height of the ullage reference point above the dip point on the bottom of the tank.

n: 1. the point at which a tape is lowered and read on a tank, usually at the rim of the hatch, manway, or expansion dome.2. a point to which all subsequent measurements are related.3. the point from which the reference height is determined and from which the ullages/innages are taken.

n: see ullage.

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: a correction applied to cargo ullages when the vessel is not on an even keel. Valid only when liquid completely covers the tank bottom and is not in contact with the underside of the deck.

n: the amount by which a tank or a vessel is short of being full, especially on ships. Ullage in a tank is necessary to allow space for the expansion of the oil in the tank when the temperature increases. Also called outage.
