1results about How to "No fluctuations" patented technology

This application relates to a flow measurement method, apparatus, computer equipment, storage medium, and computer program product. The method includes: when the error of the flow measurement result exceeds the allowable error range, adjusting the flow measurement pipeline to a first state where it is filled with liquid and the liquid is stationary; performing zero-point calibration on the flow measurement parameters based on the first state to obtain zero-point calibration parameters, so that the flow velocity measurement result obtained based on the zero-point calibration parameters in the first state is zero; adjusting the flow pipeline to a second state where it is filled with liquid and the liquid is flowing, and obtaining the instantaneous flow velocity measurement result in the second state; obtaining the full-scale coefficient in the flow measurement parameters, and obtaining a corrected full-scale coefficient based on the instantaneous flow velocity measurement result and the cumulative flow of the liquid during the sampling period; and measuring the flow rate of the liquid in the pipeline based on the corrected full-scale coefficient and the zero-point calibration parameters to obtain the measurement result. This method can achieve accurate measurement of the flow rate of fluid in a pipeline.
