Numerical Simulation on the Flow Field inside an Ultrasonic Water Meter

Abstract:

Flow field inside an ultrasonic water meter of time-difference-type are numerically simulated at several flow rates. Linear mean velocity (LMV) averaged along the line between the transmitting transducer and the receiving one, and the surface mean velocity (SMV) averaged in the cross section of the reducing-type flow passage, and the flow correction coefficient are calculated with the flow field data obtained by the simulation. Its found that the values of flow correction coefficient for the reducing-type meter channel flow are quite different from that for a fully developed pipe flow, and are related to the flow rate or Reynolds number.
