  • Self-alignment filling level detecting device
    Patent number: 9151656
    Abstract: A self-alignment filling level detecting device has a reflector and a sensor detachable from each other. The sensor has a light emitter, a light sensor, and a controller. The light sensor receives different light intensities when the reflector is assembled to the sensor and when the reflector is not assembled to the sensor. Thus, the controller determines whether the reflector has been accurately engaged and aligned with the sensor or not based on sensing results of the light sensor. Since the reflector and the sensor are detachable from each other, either the reflector or the sensor can be replaced individually if any one of them malfunctions.
