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.
