Abstract
A novel method for estimation of unsteady flowrate using pressure at two or three points along a pipeline is described in this paper. The pressure data are processed using a wave propagation model to determine the unsteady flow. Computer simulations show that the proposed method is effective for unsteady flowrate measurement to a high bandwidth. However, if the pressure values from two transducers are used, inaccuracies exist at certain frequencies when the transducer spacing coincides with multiples of half a wavelength. The accuracy can be improved by adding a third transducer with unequal spacing. The comparison and analysis of two-transducer and three-transducer techniques are investigated through simulation. This method may be applied to real time flowrate measurement, control systems or active noise cancellation systems.
