| 摘要 | PURPOSE:To enable long-term employment of the device by providing a wave- height measuring part delivering a signal corresponding to the height of a wave on a water level and a control part outputting a start signal to a recording part when the output signal of the measuring part exceeds a prescribed value. CONSTITUTION:The control part 2 has a setting part 9 which is capable of generating a signal corresponding to a set and desired value of wave height as well as a discriminating circuit 10 sending out a prescribed control signal when the output signal of the 2nd integrating circuit 8 exceeds the output signal of the setting part 9. A flow-speed measuring part 3, a flow-speed detecting terminal 11, a flow-speed measuring circuit 12 and a flow-speed recording part 13 are provided, and the recording part 13 is started and stopped correspondingly to the control signal sent out from the control part 2. When the value of the height of the wave on the water level is larger than the desired value of the height of the wave set in the setting part 9, the recording part 13 starts recording operation based on a starting signal sent out from the control part 2, and the data of flow speed is recorded only at the time of the desired value of the height of the wave. Since the recording operation is not performed when the height of the wave is low, the same condition with the increase in recording capacity appears. | ||||||
