Abstract: A sonic water level metering method is economic and can remove the probability of failure in case of using a plurality of sound wave receivers by using only one sound wave receiver. A sonic water level metering method comprises the following steps. A waveguide, a sound wave transmitter, a sound wave receiver and a controller are prepared(S10). A first turnaround time from the point of time when the sound wave transmitted from the sound wave transmitter passes through the sound wave receiver to the point of time when the sound wave reflected from one end of the waveguide passes through the sound wave receiver is measured(S20). The sample speed of the sound wave which progresses the section between the sound wave receiver and an end of the waveguide by using the distance between the sound wave receiver and an end of the waveguide and the first turnaround time(S30). A second turnaround time from the point of time when the sound wave transmitted from the sound wave transmitter passes through the sound wave receiver to the point of time when the sound wave reflected from the water surface at the other end of the waveguide passes through the sound wave receiver again is measured(S40). The distance between the water surface and the sound wave receiver is obtained by multiplying the second turnaround time by the sample speed and dividing by 2(S50).
