n: in a pipe prover, an electrical switch activated by the displacement sphere as it moves through the U-portion of the prover. Activating the switch sends an electric current through a cable to a pulse generator.

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: any of the various techniques by which the whole number of meter pulses are counted between two events (such as detector switch closures). Any remaining fraction of a pulse between the two events is calculated.
