A particulate monitoring system includes a conduit in which to a pass a fluid sample from an input port to an output port. The particulate monitoring system receives a fluid sample inputted to the conduit through the input port. The fluid sample can include different sizes of particulate matter. The particulate monitoring system controls a flow of the fluid sample through the conduit to age the particulate matter. Gravitational forces cause a portion of the particulate matter in the fluid sample to fall into a basin as opposed to being exhausted through the output port, which is disposed at a vertically higher level of the conduit than the input port. Thus, the particulate monitoring system outputs a portion of the original particulate matter in the fluid sample (e.g., particulate matter that does not drop into the basin out due to gravity) for analysis.

Particulate matter monitor

According to example configurations herein, a fluid sample flow including particulate matter passes through a conduit. One or more optical sensors monitor optical energy scattering off of the particulate matter in the fluid sample flow as it passes through the conduit. A magnitude of the optical energy sensed by the one or more optical sensors varies depending on particulate matter present in the fluid sample flow. An analyzer monitors the magnitude of the optical energy sensed by the one or more optical sensors and detects changes in the optical energy. A change in the optical energy can indicate a change in the particulate matter present in the fluid sample flow. In response to detecting the change in the optical energy, the analyzer initiates one or more functions such as recalibration, purging, execution of diagnostics, etc.
