测量下限由0.07 m3/h降为0.035 m3/h。

Abstract

In order to minimize the minimum measurable flow rate

tangential turbine flowmeter in heat meter with diameter 25 mm is taken as an example

computational fluid dynamics（ CFD） simulation software is adopted to research three-dimensional flow field in sensor

ten kinds of improved schemes are presented to improve performance of sensor. The best scheme is selected according to prediction of the optimized sensor performance using CFD simulation. The results indicate that the minimum measurable flow rate changes from 0. 07 m3/ h to0. 035 m3/ h.
