PR-015-10603-R01 Effect of Upstream Piping Configuration on Ultrasonic Meter Bias
Author(s): Hawley, George
Abstract/Introduction:
The goals of this project were twofold: (1) to test various piping configurations that are typically installed upstream of the AGA-9 recommended default meter run to determine if the configurations can cause significant installation bias, and (2) to determine if any of the tested configurations cause sufficiently little bias to become acceptable design practice. The approach was to use three commercially-available ultrasonic flow meters to monitor changes in flow measurement accuracy and variations in the velocity profiles from common piping configurations typically installed upstream of the AGA-9 recommended default meter run. The tests were performed under controlled conditions in the SwRI Metering Research Facility (MRF) High Pressure Loop (HPL) and were designed to compare a baseline unidirectional AGA-9 recommended default installation, without upstream piping disturbances, to common piping configurations with piping disturbances upstream of the baseline run.

PR-369-08609-R02 Investigate Active Meter Cleaning Concepts (Phase 2)
Author(s): Gipson
Abstract/Introduction:
Due to having the entire process video taped the requirements were to followup with a brief summary of the process high lighting attributes and possible concerns of this process. We feel that this process will provide the requirements that were requested in the beginning of
this project from the PRCI Team Members. In this process we have taken in first the safety issues, second efficiency of the cleaning process, and replacing the cleaning process over the traditional disassembly methods.
