Abstract

The blockage of the sensing lines of a differential- pressure (DP) flow sensor has been found to be the main cause of mayunction of Q flow measurement system in many industrial processes. A novel method based upon wavelet transforms for the self-validation of the DPflow sensor is presented in this paper. Unlike a conventional DP flow sensor that provides only measurements, a sevvalidating version of the sensor developed enables its measurements to be accompanied by a validity index. Namely, the accuracy of the measurement is reflected by the validating uncertainty whilst the normality of the measurement is indicated by normallabnormal sensor operating status. Experimental results of a designed prototype sensor have verified the effectiveness of the approach.
