摘要： An ultrasonic flow rate measuring method comprises steps of measuring an inner diameter of a pipe in a manner to subtract a corrosive resistance layer and its possible thickness deviation from the maximum deviation of an inner diameter presented as a pipe size within the range of being able to be estimated, measuring a flow rate QI of the ideal circular section having the measured inner diameter based on the ultrasonic multi-channel flow rate measuring method, calculating a flow rate QII of the remaining section according to a flow velocity distribution curve and adding the flow rate QII to the flow rate QI to calculate a total flow rate Q. Therefore, the method can enhance the accuracy of the flow rate measurement, if the section area of a pipe can't be measured, exactly, and the inner diameter of the pipe has a deviation due to an ovalness.
