The effect of pipeline location on acoustic measurement of gas solid pipeline flow

摘要

The flow velocity and solids concentration in a pneumatic conveying line can be measured in-line and non-invasively from measurements of the axial propagation of active acoustic signals. This paper investigates the performance of a prototype meter in regions of developing flow, in particular after a horizontal 90° pipe bend where strong particle roping behaviour has been observed. The effect of the location of the instrumentation on the accuracy and reproducibility of the measurement is discussed.
