音波式波高計。[Scope of claim for utility model registration] (1) An ultrasonic transducer that emits ultrasonic waves from underwater toward the water surface and receives the reflected waves; In an ultrasonic wave height meter, an ultrasonic wave height meter is equipped with a noise removal gate circuit that changes the pressure according to fluctuations in the wave height and takes in only reflected wave information reflected from the gate section; An ultrasonic wave height meter comprising: a sensor; and a gate section limit circuit that determines a change limit of the gate section based on a detection signal from the pressure sensor. (2) The gate section limit circuit includes a V/F converter that outputs a frequency signal corresponding to the detected pressure of the pressure sensor; and an ultrasonic transducer that outputs a pulse signal with a time length corresponding to the frequency value of the V/F converter It consists of a pulse output circuit that outputs in synchronization with the ultrasonic pulse emitted from the pulse output circuit; and a gate circuit that prevents the sending and receiving of reflected wave information from the ultrasonic transducer while the pulse signal is being output from the pulse output circuit. An ultrasonic wave height meter as set forth in claim (1) of the utility model registration claim, characterized in that:
