Extended Measurement Range of Vortex Flow Meter in High Turbulent Range
Abstract
It is known that a vortex signal is fundamentally related to the fluid flow velocity. When, a vortex flow meter operates at a low flow velocity, the vortex signal is weak, which has been discussed by several researchers in recent years. Subsequently, when a flow meter operates at a high flow velocity, the vortex signal is superimposed on additional signals, making it difficult to extract the true vortex signal. Both problems directly influence the measurement range of a vortex flow meter. The investigation of the vortex signal in high turbulent range is rarely mentioned in literature, and is the focus of this work. A typical vortex flow meter has been optimized and its measuring range has been extended up to 55%.
