摘要：PROBLEM TO BE SOLVED: To provide a water quality measuring device having asimple mechanism and capable of obtaining high measurement accuracy. SOLUTION:When the solenoid valve 5 is periodically closed to stop the supply of fresh water fromthe nozzle 3 and the solenoid valve 7 is opened to supply compressed air to the space S,
the fresh water in the space S flows out from the opening 2. , Space S is filled with air.After that, when the solenoid valve 7 is closed and the solenoid valve 9 is opened tocommunicate the inside of the space S with the atmosphere, the water to be measuredflows into the space S from the opening 2 and the measurement is performed by thesensor body 1a.
