The cross correlation signal processing is not a new idea it has wide spread and has large numbers of applications in the engineering field. It became as a suitable tool for analysing time invariant systems and system identification dynamics. However, one of the eminent applications of cross correlation is velocity measurements in multiphase and difficult fluids such as, pneumatically conveyed solid materials, highly polluted liquids, mixture of extremely hot gases and liquids. This paper is divided into two segments practical execution and data acquisition analysis to ameliorate the accuracy of velocity evaluation. The cross correlation velocity evaluation is based on the measurement of transit time of the tagging signals of multiphase flow between two separated sensors. The number of techniques and multiphase flow sensors (MPFs) is used for velocity evaluation such as, ultrasonic sensors, capacitive sensors and electrostatic sensors etc. However, this comparative study was conducted on the coal test-rig of Teesside university while ring shaped electrostatic sensor are used to determine the velocity of gas/solid two phase flow. The acquired data of the test-rig are executed on the LabVIEW (national instrument software).
