Title: Apparatus for measuring the depth, water velocity or water temperature ofan open channel

Abstract: An apparatus for measuring the depth of water and the water temperature atany point of an open channel by measuring an ultrasonic propagation timetransmitted between a plural number of ultrasonic transducers and by acalculation using an ultrasonic velocity, wherein a slider 11 is attachedto a support 13 capable of moving up and down, which is placed in water. Afirst ultrasonic transducer 18 is fixed to the bottom of the support 13and a second ultrasonic transducer 19 is positioned above the firstultrasonic transducer 18. A third ultrasonic transducer 21 is positionedabove the second ultrasonic transducer 19 and below the slider 11 and afourth ultrasonic transducer 22 is fixed to the slider 11. Each transducerfaces with each other. The apparatus further comprises a fifth transducer23 and a sixth transducer 24 for measuring the flow velocity, both ofwhich transmit and receive ultrasonic waves.
