PURPOSE: A floc sensor assembly is provided to accurately observe a floc observing member based on an electric operative valve selectively installed at the flow path of an outlet. CONSTITUTION: A floc sensor assembly includes the flow path of an inlet(1100), the flow path of an outlet(1200), an electric operative valve(1400), a floc observing member(1300), and a sensor(1500). Both end parts of the floc observing member are in connection with the flow path of the inlet and the flow path of the outlet. The floc observing member is stood to the gravity direction. The floc observing member is transparent such that the inside of the floc observing member is capable of being monitored. A light emitting part(1510) and a light receiving part(1520) are arranged at the sensor. The sensor transmits a signal to a controlling part in order to automatically control the amount of coagulant. |
