n: a device to enable the adjusting of a meter register to indicate true volume within acceptable tolerance.

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: 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: a register that indicates the combined registration of two or more meters.

n: a relatively small calibrated tank, open to the atmosphere. Often used to prove meters at loading racks. In use, the meter to be proved is set at zero and the prover tank is filled to a calibrated height while the meter registers the amount of liquid flowing d1rough it. When the tank is filled, the calibrated volume in it is compared to the volume the meter registered. If the meter is inaccurate, it is adjusted or a factor is used to compensate for the inaccuracy.

n: a meter register that receives signals from several other meters and displays or records the sum of the readings from the other meters.
