This standard covers the procedures required to determine the field data necessary to calculate a Base Prover Volume (BPV) of a field displacement prover by the master meter method of calibration.This standard applies to liquids that for all practical purposes are considered to be clean, single-phase, homogeneous, and Newtonian at metering conditions.Detailed calculation procedures are not included in this standard, see API MPMS Chapter 12.2.5.
