SYSTEM FOR MEASURING WATER-LEVEL OF ELECTRICAL RESISTOR TYPE USING COOPER PIPE IN BRIDGE

摘要

PURPOSE: A system for measuring water-level of electrical resistor type in a bridge is provided to minimize measurement errors by using a cooper pipe which is not corroded even if it is in water. CONSTITUTION: A system for measuring water-level of electrical resistor type in a bridge comprises an anti-corrosion conductor copper pipe(120), a conductor floating touch switch(110), and a level sensor(130). The conductor floating touch switch floats on the water which flows in the inside of a copper pipe and converts current provided to the copper pipe. The resistance value changes according to the water level change in a bridge.
