Beschreibung
Zusammenfassung:	Described herein is a sensor module for sensing characteristics of a fluid flowing through a fluid conduit. The sensor module includes a sample probe with at least one sample arm that extends radially inwardly from a sidewall portion of the fluid conduit to a center portion of the fluid conduit, defines a fluid flow channel, and includes a plurality of inlet apertures. The sample probe also includes a sensor well that is located at a radially outer end of the at least one sample arm. The sensor well defines an interior volume that is in fluid communication with the fluid flow channel, an upstream portion closed to an first portion of the fluid conduit upstream of sensor well, and a discharge aperture open to a second portion of the fluid conduit downstream of the sensor well. The sensor module also includes a sensor positioned in the interior volume.
