Abstract

Orifice meters are a type of the differential pressure flow meter widely used in industrial applications dealings with measuring the size and flow rate of expensive fluids such as natural gas, petroleum and water. The measurements accuracy of these meters depends mainly on their position in a pipe network. This paper is concerned with the effect of nonstandard flow conditions generated by various fittings (e. g: reducer, single elbow, double-elbow in- plane, double-elbow out-of- plane, T-junction) at different nonstandard upstream distances of the orifice plat on velocity profile and on discharge coefficient. Both numerical and experimental studies were used to investigate this problem. The results show that for each fitting, there is a different effect on the velocity profile and on the discharge coefficient. As an example, the 90° elbows decreases the discharge coefficient with decreasing upstream distance and increasing Reynolds number. Also, after a straight distance of 40D between the elbow and the orifice plate, the velocity profile is not fully matched with the normal profile.
