Abstract

Acoustical oscillations can induce a rotation of a turbine flow meter in absence of main flow, which leads to spurious counts. A simplified model is presented to explain the onset of spurious counts in the limit of very thin turbine blades and high Strouhal numbers. A second model describes the behaviour of the turbine meter during steady rotation. The predicted data of the models are compared to experimentally obtained data at various gas pressures in the range from 1 to 8 bar. The first model is a useful engineering tool to predict the conditions under which spurious counts appear. The second model predicts the order of magnitude of spurious counts at high acoustical amplitudes.
