WATER LEVEL SENSING APPARATUS

摘要

PURPOSE: A water level sensor is provided to increase the simplicity of installation by supplying operating voltage using a solar cell. CONSTITUTION: A water level sensor comprises a water level sensing pipe(100) and a water level sensor(160). The water level sensing pipe is built in the location, for sensing a water level such, as a river and a reservoir. The water inlet, in which the water flows, is formed on the lower part of the water level sensing pipe. The water level sensor it is installed upward from downward in the inner side of the water level sensing pipe. The water level sensor comprises a base layer and a conductive line. The base layer is tape type and is composed of an insulating material. The conductive line is at least two lines formed in the side of the base layer in a longitudinal direction over.
