A low-loss and low-coefficient metering element has been devised and its operating characteristics determined under various conditions. The design was found to be not unduly sensitive to cavitation. The effects of installation have been evaluated for a short radius elbow and a tee. A partly open butterfly valve could be located 1 1/2 throat diameters downstream from the throat piesometers with an effect not exceeding 1/2 per cent upon the coefficient. Finally, the effects of pipe roughness and converging or diverging pipe can be correlated with the velocity distribution just upstream of the metering element.
