Abstract: A purifying system for treating a fluid with UV light including a housing defining: a chamber having a treatment zone; an inlet; and an outlet. The light source supplies UV light to the treatment zone. The inlet, the tubular housing, or the outlet may extend inward into the chamber so that the fluid passes close to the light source and has a relatively increased duration in the treatment zone. The purifying system may also have a sensor coupled to the housing or light source for generating a first signal indicative of a first parameter of the treatment zone. A microcontroller can control the light source based on a signal from the sensor and data characterizing the light source. The microcontroller may also vary operation of the light source and collect data to create the data characterizing the light source.

Abstract: An ultra-violet (UV) assembly for treating a fluid with UV light has a housing. A mounting bracket defines a slot and a hollow. A UV source includes: a tab that twist-locks in the slot; a connector that aligns with the hollow; and an RFID tag. An RFID antenna interacts with the RFID tag to emit a RFID tag position signal. A flow switch sends a flow signal. The flow switch includes: a guide; a shaft slidably mounted to the guide; a disc on the shaft; a magnet coupled to the shaft; and a sensor for generating a magnet position signal. During no flow, a spring biases the shaft so that the magnet is positioned to be detected by the sensor. During flow, the flow applies pressure to move the disc and, in turn, the magnet moves to be positioned to not be detected by the sensor.

Abstract: A monitoring port assembly for a fluid treatment system, such as for use in an ultra-violet water treatment system. The port assembly comprises a sensor port cup having a port for access to an interior of the fluid treatment vessel. The port is offset from the central axis of the sensor port cup. A cylindrical body, having an offset through-hole to receive a sensor assembly, is disposed within the sensor port cup for rotational movement about the central longitudinal axis between an operational position where the offset through-hole is aligned and coincident with the port, and a servicing position where the offset through-hole is displaced relative to the port. Sensors can be safely and conveniently removed from or installed into a port in the fluid treatment vessel by rotating the cylindrical body from the servicing to the operational position.
