5 Years Offshore Operational Experience of 3-Path Gas Ultrasonic Flowmeters in Custody Transfer Allocation Measurement Systems

摘要

This paper presents an overview of the practical metering issues experienced on the Custody Transfer and Allocation measurement systems onboard an installation in the North Sea. All data presented is taken from four operational and two new 3-path transit time ultrasonic meters. The data was collected over the period May 2000 to Aug 2006 and is presented blind for confidentiality. Ultrasonic measurement technology has been used by many operators in the North Sea for many years now. The paper highlights some of the potential issues facing users of this technology in Custody Transfer & Allocation applications.
