Common use of Volumetric Measurement Clause in Contracts

Volumetric Measurement. 1. Volumetric measurement shall be accomplished utilizing a flow computer, turbine meter, and temperature and pressure transmitters. A “fixed” specific gravity at 60 oF and vapor pressure at 100 oF may be entered into the flow computer in the case of “purity” products, if agreed by both parties. Temperature and pressure shall be referenced to the proper API, ASTM and GPA Tables to calculate and totalize net barrels. An optional densitometer and flow-proportional composite sampler may be installed. If a densitometer is installed, the flow computer shall convert the density signal at flowing conditions in gm/cc to specific gravity at 60 oF and use GPA TP-15 to determine EVP (Equilibrium Vapor Pressure).
