Abstract

The purpose of this research was to analyze the accuracy of a Classical Venturi meter installed downstream of the through leg of a tee junction. A flowmeter that functions inaccurately due to improper installation may cause revenue loss for any company or organization involved in extraction, transportation, production, or purchasing of fluid resources and products. This research used physical data coupled with data produced by numerical models to determine how to correct the Classical Venturi meter’s inaccuracies created by this particular installation.

Results show the capability of measuring the flow rate accurately was greatly affected when most of the flow was directed through the branch of the tee junction. As a greater ratio of water is directed through the meter, the accuracy increases. While physical laboratory calibrations remain the most effective way to ensure best metering accuracy, correction factors may be used to account for such installations if laboratory testing is not possible.
