Abstract

PURPOSE:To accurately monitor water supply control by judging the presence of an abnormality via a time check based on a normal pattern and the water supply quantity when a water level gauge is made defective. CONSTITUTION:Water level sensors HH, H, L, LL are installed on a water tank 1 as a water level gauge 2. In the case other than five patterns at the time of the normal operation: all sensors off, only LL on, LL and L on, LL and L and H on, all sensors on, the water level gauge 2 is judged as abnormal, and a warning is displayed 12. When the sensor HH is made defective, for example, in a time check of the water supply quantity, if the value added with ((Q1+Q2+Q3)divided by SXTa) to the water level H1 when the sensor H is turned on from off is larger than HH, the water level gauge 2 is judged as abnormal, and a warning is displayed 12, where Q1 is the discharge flow when a discharge valve 9 is fully opened and a sprinkling pump 10 is started, Q2 is the water supply quantity when a cascade water supply valve 8 is fully opened, Q3 is the water supply quantity when a raw water supply valve 7 is fully opened, S is the bottom area of the water tank 1, and Ta is a water supply timer time set value.
