PROBLEM TO BE SOLVED: To accurately detect water level anomaly in a distribution reservoir at an early stage, and to notify workers of the anomaly.SOLUTION: When the level of purified water W in a distribution reservoir is equal to or higher than a prescribed level, an end face of a housing 31 is pulled by a weight 35, which puts the housing in an erected position with the end faces thereof in parallel with the water surface. When the level of the purified water W is lower than the prescribed level, the weight 35 touches the bottom G of the distribution reservoir causing a string 34 to be slacked off, which allows a weight 33 fixed to the side circumferential surface of the housing 31 to put the housing 31 in a horizontal position with the end faces thereof perpendicular to the water surface. When the housing 31 remains in the horizontal position for a prescribed period of time or more, a power distribution controller supplies power from a power supply to an information communication unit which sends an email to an email address stored in a storage unit. This allows water level anomaly in the distribution reservoir to be detected and notified to workers contracted for the distribution reservoir management at an early stage. |
