摘要：

The Vortex flowmeter is one of the well-accepted modern flow measuring instruments where the frequency of vortices produced behind a blunt post is found to be directly proportional to the flow rate. There are different techniques of measurements of this frequency of vortices. In the present paper a low cost microprocessor based inductive pick-up type technique of measurement in this vortex flowmeter has been described. The operation of the developed instrument has been tested and the experimental results are reported in the paper. A good repeatability of the results has been observed. (C) 2003 Elsevier Ltd.
