Abstract

This paper presents a procedure in format of a flowchart for prover sizing based on API-MPMS Standard which can be considered as a pattern for prover sizing in field prover design and fabrication. The method was analyzed and verified for the prover of the biggest crude oil fiscal metering system in Iran, that is, bidirectional field prover of Genaveh 10 Million BBL Crude Oil Storage Tanks Fiscal Metering System Project which was designed and fabricated by Asia Instruments Co. LTD. Since this prover was designed to calibrate both heavy and light crude oil fiscal metering systems, each comprised five Ultrasonic Liquid Flow Meters of Faure Herman Co., API MPMS standard requirements for ultrasonic liquid meters were also considered in prover sizing presented method. Results indicate how commercially optimum prover dimensions can be obtained based upon project specifications and other equipment of fiscal metering system and prover.

Key words: Prover sizing, ultrasonic flow meter, detector switch.
