Abstract: The present invention relates to an ultrasonic hydrograph having an improved structure to accurately measure a level regardless of a water surface status. According to the present invention, the ultrasonic hydrograph includes: a hollow wave guide to flow in a fluid while having a plurality of through-holes; a floater arranged inside the wave guide, while being floated on the fluid; and an ultrasonic oscillator coupled to the bottom of the floater to transmit and receive an ultrasonic wave. The ultrasonic wave transmitted towards the bottom of the ultrasonic oscillator progresses through the fluid, and is reflected from the floor surface to be received by the ultrasonic oscillator. The time required for the above process is used to measure the level of the fluid.
