Abstract

Abstract: Development of an accurate and reliable differential pressure flow meters is needed for industry. The relationship between the Reynolds number (Re) and the discharge coefficient ( Cd ) was investigated using a differential pressure flow meter. Venturi meter is a type of baffle meter, widely used in industry for flow measurement. The ISO standard (ISO-5167-1) provides discharge coefficient values for classic Venturi tubes in turbulent flow with Reynolds number values above 2x10 5 . This study shows that various discharge coefficient decrease rapidly and constant discharge coefficient values vary with meter design. The main focus of this study is to compare experimental results with theoretical predictions and estimate the optimal value of thevmeter discharge coefficient at various flow rates. The experimental results showed that the optimal value of the venturi tube discharge coefficient of about 0.983 was obtained.
