The influence of upstream pipe roughness on the performance of multipath ultrasonic flow meters was examined through a set of experiments involving three different brands of ultrasonic flow meters. Tests were conducted with 16-inch meters with piping, having a wide variation in surface roughness values with and without a flow conditioner. These results, when combined with the earlier testing of 8-inch diameter meters, can be used to support changes in the practices currently recommended by industry standards.
