Abstract

In order to verify the rationality of the straight pipe's design for the ultrasonic heat meter calibration device, the Computational Fluid Dynamics(CFD) was used to the simulation for the DN25 heat meter, the straight pipe length of the domestic typical structure ultrasonic heat meter was determined through the analysis of the velocity distribution’s difference in the straight pipe. It is gained that the straight pipe length before the heat meter is more than 14D, the straight pipe length after the heat meter is more than 8D with the velocity distribution curve similarity in more than 99.5%, and when multiple heat meters are connected in series, the last one is not affected by the previous one, the rationality of the design is confirmed, and it provides the theory basis for the design of the calibration device, and ensures the reliability of the measurement results.
