This chapter describes the methods, equipment, and procedures for manually determining the temperature of liquid petroleum and petroleum products with liquid-in-glass thermometers. This chapter discusses temperature measurement requirements in general for custody transfer, inventory control, and marine measurements. The actual method and equipment selected for temperature determination are left to the agreement of the parties involved. The manual method covers: — non-pressurized tanks and non-pressurized marine vessels; — gas-blanketed tanks and gas-blanketed marine vessels.
This testing protocol provides the minimum requirements for documenting performance testing of an inline multiphase flow meter under controlled flowing conditions in a flow loop facility. Completion of the testing protocol is not a calibration and does not replace field testing and validation.
Measurement of flow to flares is important from accounting, mass balance, energy conservation, emissions reduction, and regulatory perspectives. Flares are safety relief systems that typically receive highly unpredictable rates of flow and varying compositions, and for safety reasons do not often lend themselves to being taken out of service to accommodate measurement concerns, even for short periods.
