1. The first and second makeup water meters 25 and 32 can calculate the amount of makeup water for the first and second circulation tanks 22 and 32, respectively.
2. When the circulating water runs, the first bypass valve 20 and the second bypass valve are adjusted according to the reading of the first electronic flowmeter 17 and the reading of the second electronic flowmeter 11, so that the systems where the first circulating water pool 22 and the second circulating water pool 32 are respectively located pass through the circulating water with the same water quantity.
3. The system operates as the water vapor evaporates and the first recirculating water sump 22 drops in water level, causing the first mechanical float switch 24 to close and replenish water from the refill tank 26. When the water level rises, the first mechanical float switch 24 is switched off, the water supply from the water supply tank 26 is stopped, and the water is supplied to the second circulating water tank 32 in the same way.
