A sensor system for sensing contaminants within a fluid stream of a fluid system includes a sensor body and an arm extending from the sensor body to a distal end of the arm, a laser light source configured to direct a laser beam outwardly from an outlet of the sensor body, and a light sensor. A fiber optic light guide is disposed in the sensor body and extends from the light sensor to an inlet of the sensor body for directing light to the light sensor. A beam dump is positioned at the distal end opposite the laser light source to absorb at least a portion of the laser beam directed towards the distal end. A blocking member of the arm is disposed intermediate between the sensor body and the distal end and is configured to partially restrict a field of intake of light at the inlet.

Sensor system for detecting contaminant in fluid

A flow meter includes a magnet actuated switch, and an impeller configured to be insertable into a standard NPT &#xbc;&#x2033; pipe fitting. Rotation of the impeller in response to a fluid flow actuates the magnet actuated switch with a frequency that is proportional to a flow rate of the fluid flow. The impeller has a cylindrical shaft and a plurality of extensions that extend from the cylindrical shaft that form a spiral shaped cross section. Each extension has an inner curved surface and an outer curved surface, and the inner curved surface is concave shaped to catch the flow of the fluid, and the outer curved surface is convex shaped to provide reduced counter resistance to the rotation of the impeller. A pipe section assembly includes a pipe section including a standard NPT &#xbc;&#x2033; pipe fitting and the flow meter vertically inserted into the pipe fitting.
