PROVER, LIQUID VOLUMETRIC POSITIVE DISPLACEMENT METER
|Publication Date:||5 April 2011|
The meter prover is used to verify readings on displacement and turbine meters such as permanently installed meters used with truck fill stand installations or meters mounted on mobile refueling equipment such as the R-11 6000 gallon refueler and R-12 Hydrant Refueler. The prover is designed for the verification of positive displacement and turbine meters within the operational flow range of 30 GPM to 600 GPM with operating pressures not to exceed 150 psi. The meter prover consists of a trailer chassis and running gear that contains a master meter, suitable inlet and outlet piping and connections, discharge hoses and nozzles, control valves, check valve after meter, and pressure and 2 temperature gages. The master meter prover will be designed in accordance with API MPMS 4-1 and 4-5.
