In order to solve problems existing in the traditional flow rate measurement of time-difference ultrasonic heat meter such as large amount of calculations and complex measurements,we conducted a deep study on the linear regression algorithm and subsection interpolation algorithm and developed a new method to calculate flow rate,which was implemented directly by the meas-urement of time lag,and avoided the influence of uneven distribution of fluid and the change of temperature to the measurement ac-curacy.Tests show that the flow rate measurement results of heat meter based on this algorithm are closer to real value.There is no doubt that it has a certain guiding significance on the precise measurement of flow rate.
