Research on Flow Calculation Method Based on BP Neural Network

Based on the relationship between flow and pressure in the flow standard facility, a BP neural network calculation model is established in this paper considering the influence of parameters like valve opening and pump frequency. Through the flow measurement experiment, the training and testing sample data are obtained, and then the established BP neural network model is trained and tested. The calculation results show that the established BP neural network model can accurately obtain the instantaneous flow value through the pressure in the pipeline.
