Flow rate measuring system and method for multiphase fluid

Abstract

The invention relates to the technical field of fluid measurement, and provides a flow rate measuring system and a flow rate measuring method for multi-phase fluid. The system comprises a measurement module, a signal amplification module, a data processing module and a terminal module which are connected in turn, wherein the measurement module at least comprises two measurement devices arranged on a pipeline at a certain interval, and the two measurement devices respectively measure the content of the same element passing the sections where the devices are positioned by a nuclear physics method; the signal amplification module is respectively connected with the two measurement devices and amplifies signals acquired by measurement; and the data processing module converts the signals into digital signals first, then performs digital lowpass filtering treatment and quantization treatment on the digital signals, establishes a mathematical model by utilizing a cross-correlation function principle, performs data analysis treatment on the digital signals, and outputs results of a flow and a flow rate to the terminal module. The system and the method reduce the measuring complexity, reduce corresponding errors caused and improve measuring accuracy and reliability.
