Filed: 1978-05-18
Abstract: PURPOSE: To diminish the required installation area and facilitate maintenance and checking, by floating a float having a water quality detector supported in the lower part thereof on the surface of water, and providing a lifting mechanism in the detector.  
     CONSTITUTION: A float 8 having a water quality detector 2 supported in the lower part is floated on the surface of water in a water tank 1. When the water level fluctuates, the float 8 moves up and down accordingly along a guide wire 10. Therefore, the lower detecting part of the detector 2 is always kept beneath the fixed surface of water, and the float 8 does not move on the surface of water even if the water runs in stream. Hence, always correct measured values may be outputted in a display part 4. Also, by lifting the wire 12 by means of a winch 14, the detector 2 and float 8 may be lifted away from the surface of water, so that the detector 2 may be serviced or checked easily. In addition, because of such constitution, the installation area may be decreased.
