Abstract

 Many research and development has been done for flow rate measuring methods of rivers and so on, and they have been put to practical use both in Japan and abroad, but as far as we know there is no way to automatically and continuously measure river water from low to high level water. We have developed a sensor called a point current sensor, aiming at a system which can combine small radios, networks and proprietary web servers to automatically measure river flow and can deliver in real-time. Since the point current sensor is compact, inexpensive, consumes less power based on the simple principle using a reed switch. It is suitable for combination with a wireless device and is unnecessary to construct a large-scale cable under the river bed, therefore it is easy to install. In this paper, we explain the idea of the flow rate measurement system, the principle of a point current sensor and the solution method of the problem found in the field experiment so far and also show the development situation of the whole system.
