Monitoring port assembly for fluid treatment systems
First Claim
1. A monitoring port assembly for use in a fluid treatment vessel, the assembly being configured for installation in an opening in a wall of the fluid treatment vessel, the monitoring port assembly comprising:
- a sensor port cup having a port permitting direct access to an interior of the fluid treatment vessel when the monitoring port assembly is installed therein, the port being offset from a central longitudinal axis of the sensor port cup; and
a cylindrical body having an offset through-hole to receive a sensor assembly, the cylindrical body being 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 to position the sensor assembly for direct contact with fluid in the interior of the fluid treatment vessel when the monitoring port assembly is installed therein, and a servicing position where the offset through-hole is displaced relative to the port and the cylindrical body sealingly engages the sensor port cup to permit installation or removal of the sensor assembly and to prevent fluid egress from the fluid treatment vessel when the monitoring port assembly is installed therein.

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.
