Abstract: PURPOSE: A method for correcting the deviation of an ultrasonic flow meter is provided to calculate correction deviation reflecting an installation position and the Reynold's number to a flow rate deviation correction curve being calculated by the Pascal's triangle and a Levenberg-Marquardt algorithm, thereby accurately calculating the deviation generated by a rotary current. CONSTITUTION: A method for correcting the deviation of an ultrasonic flow meter is as follows. A flow rate deviation correction curve is calculated based on two variable values for correcting the deviation of an ultrasonic flow meter(S100). The two variable values are calculated based on the Reynold's number related to properties of a fluid flowing in a pipe in which an ultrasonic flow meter is installed and a position of the ultrasonic flow meter(S200). An output variable of the flow rate deviation correction curve is calculated based on an instructing value measured by the ultrasonic flow meter and a reference instructing value measured by a reference flow meter(S300). A coefficient of the flow rate deviation correction curve is calculated based on the two variable values and the output variable(S400). A correction deviation is calculated by reflecting the Reynold's number and an installation position of the ultrasonic flow meter to the flow rate deviation correction curve in which the coefficient is reflected(S500). A measurement value of the ultrasonic flow meter in which the deviation is corrected based on the instructing value measured by the ultrasonic flow meter and the correction deviation(S600).
