n: a device used to determine the accuracy of a petroleum measurement meter.

n: appratus that checks the precision of petrolum gauge.

n: a device used to connect the prover to the pipeline either upstream or downstream of the meter to be proved.

n: an electronic device that counts each pulse generated by a meter transmitter.

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: see pipe prove!:

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.

n: a tank used to calibrate liquid flow meters. See open tank prove!:

any land owned by the government in the US. May compare to Crown or Federal lands in other countries.

n: a kinds of sealing method when the loss of circulation happened, firstly pulling the bit in the casing and waiting a while, then recovering drilling.
