| 摘要 |
The present invention provides a method for calculating flow rate of a fluid using a pressure differential device, based on detected pressure and temperature upstream of and detected pressure adjacent a flow constriction of the pressure differential device, and calibration coefficients calculated from the results of a flow calibration performed on the pressure differential device. By incorporating the results of the flow calibration in the computation, a non-iterative method for obtaining mass flow rate is realized.
