Abstract

As a new type of flow meter without movable parts, ultrasonic water meter has the advantages of high sensitivity, large measurement range, high repeatability and small start flow. It has been applied to the main pipe network of urban water supply system. However, the ultrasonic water meter using for domestic area has the problems in small pipeline due to the short acoustic path. In order to solve the above problems, the two type’s ultrasonic water meters with U-shaped acoustic path are designed. The CFD fluid simulation technology is used to simulate the two pipelines. The velocity map of the horizontal section and the vertical section are extracted respectively. The relationship of flow rate and flow correction coefficient is analyzed at the direction of flow and pipe section. The flow rate variety is also analyzed. The simulation results show that the brace pipeline has more stable flow field area and better symmetry. The final experimental results show that the characteristics of the brace pipeline are better than the column pipeline.
