摘要： PURPOSE: A method for determining the receiving point of an ultrasonic wave is provided to enable the flow rate and the flow velocity of the fluid to be accurately measured by the accurate setting on the receiving point of an ultrasonic wave. CONSTITUTION: A method for determining the receiving point of an ultrasonic wave is as follows. A first detected level is set, which exists on one of a positive phase and a negative phase(S10). A second detected level is set, which exists on the other phase and has a difference from a zero level which is smaller than the difference between the first detected level and the zero level(S20). It is determined by the monitoring of the amplitude of an electric pulse packet whether the electric pulse packet crosses the second detected level(S30). After the crossing, it is determined whether the electric pulse packet of the opposite phase of the second detected level crosses the first detected level(S50).
