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. © 2003 Elsevier Ltd.

Flow past bluff bodies is abundantly studied in the literature. However, confinement effect imposed by a circular pipe on the shedding characteristics of bluff bodies is rarely addressed. Application of such configuration can be seen in vortex flowmeters, heat transfer enhancement devices, energy harvesting devices etc. The present study highlights the influence of circular pipe on the shedding characteristics of two dimensional bluff bodies. The discussion is focused towards the design issues pertinent to vortex flowmeter. Nonlinearity in St-Re D relation is due to transition from laminar to turbulent flow. Cross correlation technique and contraction cone design can be employed in transition regime to extend lower operating range. Further, there is a need to explore bluff body shapes which can be used for flow measurement in laminar, transition and turbulent flow regimes. The fundamental discussion reported in this study will impart new insights towards improving the performance of these devices further. © 2019 Elsevier Ltd

On the linearity, turndown ratio and shape of the bluff body for vortex flowmeter

This paper highlights various aspects of design of a vortex flowmeter. Vortex shedding and vortex flowmeters are known from decades. However, the vortex shedding phenomenon is not understood clearly as applicable to vortex flowmeter. In the recent past large body of literature is reported on the performance of vortex flowmeter. This report comprehensively summarizes all the improvements which help the designer to build a vortex flowmeter. The paper systematically explains various aspects related to development of a vortex flowmeter with peculiarities associated with its design. © 2011 Elsevier B.V. All rights reserved.
