Validation of a mathematical model of ultrasonic cross-correlation flow meters based on industrial experience

Abstract

In 2020, Ton [1] published an article named “A mathematical model of Ultrasonic Cross-Correlation Flow Meters Based on Industrial Experience” from here on it will be referred as “the model”. The model provided detailed mathematical derivation for the entire process involved in ultrasonic cross-correlation flow measurement (USCCFM). As such, the inputs and output parameters involved in USCCFM are defined, so their relationships are also described. Based on these relationships, the output parameters behavior of the model can be predicted by the input parameters variations. These relationships are exploited to validate the model. The results of this article show the USCCFM output parameters behave exactly as the model predicted in lab and field measurement conditions. Simulated data produced by an emulator further validate the model. Furthermore, the measured time delay error (using emulator) is within 0.1 ms of the set points. This result assures that USCCFM can measure the time it takes the flow to carry the signature from upstream to downstream very accurately.
