Abstract:
To maintain high measurement accuracy and to improve maintenance for stored water quality by suppressing the contamination of a contact part with the water to be measured.
When a control section 10 opens a valve 13 and turns an air pump 11 on, air jets out from an underwater air nozzle 14. A portion of the stored water 1 adheres to a groove section 3a of a measuring object water adhesion member 3. Next, a light source 6 turns on and a camera 5 starts a photographing operation. After the photographing, the control section 10 turns the air pump 11 on in, opening a valve 15 and jetting the air from an air nozzle 16 to remove the adhered water. As a result, the measuring object water 4 in the groove section 3a is removed.
