MEASURING DEVICE FOR FLOW SPEED AND FLOW RATE, AND MEASURING SYSTEM USING SAME

摘要

The present invention relates to a measuring device comprising: a float body (110) moving together with a body of water; a GPS receiving unit (120) mounted in the float body (110) for receiving GPS location information; and a location and time information transmission unit (130) for transmitting the received information of the GPS location and the measured time; and to a measuring system employing the same. Advantages of the present invention include a significant reduction in errors compared to the convention depending on the visual observation, a rendering of the requirement of multiple workers for the measurement unnecessary, a reduction in working time due to the possible simultaneous measurement even in the case multiple floats are dropped, a precise measuring capability even in rainy weather or at night, and a minimization of errors measured even in flood seasons in which the flow rate is fast and rapidly changed.
