The ability to accurately measure the flow in a closed conduit is essential for utility managers. Although recent technological advances have produced various types of flow measuring devices, Venturi meters remain a popular choice because of their high accuracy and low head loss. Because water suppliers are increasingly using these meters for fiscal metering, a Venturi meter must be as accurate as possible. Although the standards vary for different Venturi flow meters, proper installation is crucial for obtaining an accurate flow measurement. In this study, tests were performed to determine the effects of a short-form Venturi meter on the discharge coefficient when the device was installed in piping with straight lengths shorter than those set forth in the standards. The tests showed that short-form Venturi meters generally perform within the desired accuracy range, even when placed in nonideal piping configurations. Includes 6 references, tables, figures.
