n: the procedure required to determine the relationship between the true volume of liquid measured by a meter and the volume indicated by the meter.

n: a device in a pipe prover that. when actuated by the displacer sphere. registers pulses sent from a pulse generator on the meter being proved. By reading the number of pulses the counter registers, the amount of oil or liquid product the meter registered as having passed through the prover can be determined. The amount the meter registered is then compared to the known volume of the prover to determine the meters accuracy. See meter prove1;pipe prove,;

n: any single prover volume measurement in a set of prover volume measurements required to prove a meter.

n: the instantaneous display of the number of units of volume or equivalent thereof read directly from a meter register.

n: a device that accumulates and displays the indicated volume passed through a meter.

n: the volume of liquid at a given flow rate that passes through a meter without being measured.

related to the amount of fluid that slips by a meter without being accurately recorded.

n: a complete separator and volume meter integrated into a single vessel. Two-phase units separate oil and gas and meter the oil;three-phase units separate oil, water, and gas and meter the oil and water.

n: on the basis of huber -wellise method, lead in variable base rock stress factor Ki , the caculation model is as follow: Pf=P+Ki( p0-p）。

n: a decimal system of weights and measures based on the metre as the unit of length, the gram as the unit of weight, the cubic metre as the unit of volume, the litre as the unit of capacity, and the square metre as the unit of area. The international system of measurement (SI) is based on the metric system.

n: a naturally occurring flake material of varying size used in combatting lost circulation. Chemically an alkali aluminum silicate.

a silica mineral, often present as ultra thin flakes and sometimes mobile.
