Venturi flowmeters have been used to measure flow in piped systems for over 100 years (Finnemore & Franzini, 2006). There has been much research on the performance of Venturi flowmeters and for that reason they have become popular flowmeters used in various municipal and industrial applications. Venturi flowmeters can be calibrated in a laboratory setting to find their performance characteristics. In order for the flowmeter to achieve optimum performance, the flowmeter should be installed with sufficient length of straight pipe immediately upstream of the flowmeter. Often Venturi flowmeters that are not installed in ideal conditions produce errors and uncertainty is introduced to the flow measurement. This study used multiple tap sets on Venturi flowmeters in order to reduce error and uncertainty when a Venturi flowmeter is installed in non-ideal conditions. The multiple taps sets were used to measure an average of the hydraulic pressure within the flowmeter.
