Influence of Medium Type on Measurement Performance for Vortex flowmeter
Abstract
The verification medium of vortex flowmeter in the laboratory is often different from the actual measurement. It is very important and necessary to quantitatively analyze the influence of the medium type on its measurement performance. So it is very important and necessary to quantitatively analyze the influence of medium type on its metering performance. The instrument coefficient and indication error of the same vortex flowmeter are verified by water, diesel and air at different flow velocity points, and the measurement performance difference is analyzed which caused by the medium type. The experimental results are that the instrument coefficients by three media are some different under the conventional flow velocity, but not exceed 1/3 of the maximum allowable error, and the indication error is below 1.0 %, which meets the accuracy requirements. The conclusion is that the influence of the medium type on the measurement performance of the vortex flowmeter is small, and the result qualified by air, water or diesel can be used for other media, which can meets the requirements of the accuracy level.
