A PIV EXAMINATION ON THE PERFORMANCE OF ULTRASONIC HEAT METER RELATED TO INSTALLATION

Abstract

An experimental investigation was carried out on the performance of an ultrasonic heat meter with interference of non-uniformity from the upstream installation of a ball valve, which it is partly opened. It was found that the existence of the ball valve may under-report the flow, especially when the flow rate is low. From the measured PIV results, it can be found that the velocity distribution is obviously non-uniform inside the meter, and the change is remarkable when the inlet is added with a ball valve. The time resolved PIV results also demonstrate that the flow field becomes unsteady when slow down the flow rate, which might be responsible for the measurement deviation.
