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: pulses per barrel. See pulse generator:

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. a generator that produces repeating pulses or pulses initiated by signals. 2. a displacement meter accessory coupled to the measuring element and designed to produce a series of electrical pulses whose number is proportional to the volume measured and whose frequency is proportional to the flow rate. Also called pulser.

n: a device in a pipe prover system that senses and counts the number of pulses put out by a pulse generator on the meter being proved. Pulse count relates to the amount of fluid that flows through the meter.

n: see pulse generator.
