n: a spherical or cylindrical object that is a component part of a pipe prover that moves through the prover pipe. The displacer has an elastic seal that contacts the inner pipe wall of a prover to prevent leakage. The displacer is made to move through the prover pipe by the flowing fluid and displaces a known measured volume of fluid between two fixed detecting devices.

n: the multiple passes or round trips of the displacer in a prover for purposes of determining a meter factor. v: to establish the meter factor by comparing meter through-put to a prover of known volume.

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: 1. an accurately calibrated, usually U-shaped, pipe used to check, or prove, the accuracy of a meter on a LACT unit or other oil measuring installation. 2. a type of continuous-flow volumetric prover comprising a length of pipe from which a known volume is displaced by a displacer to or from a meter being proved at normal operating conditions.

n: a spherical or cylindrical object that is a component of a pipe prover. It has an elastic seal that contacts the inner pipe wall of a prover to prevent leakage. Flowing fluid causes it to move through the prover pipe, and as it moves it displaces a known measured volume of fluid between two fixed detecting devices.

n: 1. one movement of the displacer between the detectors in a prover. 2. the volume determined by a displacer traveling between detector switches in a single direction.

n: 1. the forward and reverse passes in a bidirectional prover. 2. the volume determined by a bidirectional displacer traveling between detector switches in one direction and in the return direction.
