Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a drug infusion device for a cooling tower capable of securely detecting a situation where a cooling water circulation pump is operated to sprinkle cooling water on a water sprinkling board and thus, securely controlling a drug feed pump. SOLUTION: The drug infusion device for the cooling tower provided on a filler of the cooling tower and having the water sprinkling board making cooling water to be cooled flow down from a water sprinkling hole opened on the bottom to a clearance of the filler includes: a water level detection sensor placed on the water sprinkling board and sensing change in an electric resistance value; a control device receiving the change in the electric resistance value and generating and outputting a drug feed pump operation signal for controlling the operation of the drug feed pump; and the drug feed pump operated based on the drug feed pump operation signal. A sensor part is stored in a cover including an inner space communicated with an external environment. COPYRIGHT: (C)2011,JPO&INPIT
