PROBLEM TO BE SOLVED: To provide an ultrasonic wave flow rate switch that allows users to accurately transmit a setting content, and allows the users, manufacturers or maintenance business operators to accurately grasp the setting content.SOLUTION: In a state where two ultrasonic wave elements are anchored to an exterior face of piping, an ultrasonic wave is alternately transmitted to a fluid body flowing in the piping from two ultrasonic wave elements, and the ultrasonic wave from the fluid body flowing in the piping is alternately received by two ultrasonic wave elements. In a storage unit, setting information including information about the piping and a setting code corresponding to the information on at least the piping of the setting information are stored. On the basis of an output signal of two ultrasonic wave elements, and the setting information to be stored in the storage unit, a flow rate flowing in the piping is calculated by a flow rate calculation unit. Users, manufacturers or the like operate an operation unit 822, and thereby the setting code stored in the storage unit is displayed on a display unit 821.SELECTED DRAWING: Figure 14 |
