Abstract
In general, techniques are described for filter media monitoring within a filtration system. The filter media monitoring techniques described herein include, for example, direct contact with the filter media, e.g., a sensor may be located inside a boundary defined by a surface of the filter media, or indirect contact with the filter media, e.g., a sensor may be located outside the boundary defined by the surface of the filter media such that the sensor does not make direct physical contact with the filter media being monitored.
