Liquid hydrocarbons — Dynamic measurement — Statistical control of volumetric metering systems

In dynamic measuring systems the performance of meters for liquid hydrocarbons will vary with changes in flow conditions, viz. flowrate, viscosity, temperature, pressure, density of product, and with mechanical wear. Has been prepared as a guide for establishing and monitoring the performance of such meters, using appropriate statistical control procedures for both central and on-line proving. These procedures may be applied to measurements made by any type of volumetric or mass metering systems. The procedures to be followed for collecting data, on which the control limits are based, are described.
