n: a chart of successive meter factors (or relative meter errors) generally plotted as a function of time. Used to evaluate meter stability and to determine when meter performance has departed from its normal range.

n: 1. an ocean currents speed of motion. 2. an observed change, usually uncontrolled, in meter performance, meter factor, etc., that occurs over a period of time. v:1. to move slowly out of alignment, off center, or out of register. 2. to gauge or measure pipe by means of a mandrel passed through it to ensure the passage of tools, pumps, and so on.

n: an electronic register capable of expressing true throughput volume. It includes selective means for automatically applying meter factor.

n: the indicated throughput corrected only for meter performance (i.e., by multiplying by the meter factor).

n: (GSV) the total volume of all petroleum liquids and sediment and water, excluding free water, corrected by the appropriate temperature correction factor (Ctl)for the observed temperature and API gravity, relative density, or density to a standard temperature such as 60�F or 15�C, and also corrected by the applicable pressure correction factor (Cpl) and meter factor.

n: the indicated volume multiplied by the meter factor for the particular liquid and operating conditions under which the meter was proved.

n: the flow range over which the meter factor does not deviate from specified limits.

n: see meter factor.

n: see meter factor.

n: a number used to correct a meters inaccuracy. The factor is derived by dividing the actual volume of liquid passed through a meter during proving by the volume registered by the meter. For subsequent metering operations, the actual throughput, or gross measured volume, is determined by multiplying the indicated volume registered on the meter by the meter factor.

a correction factor applied to a meter to increase measurement accuracy in a range.
