Abstract
A particulate filter is provided. The particulate filter includes: a plurality of sensors located in the filter; and a controller operatively connected to the sensors to determine a relative flow velocity over the sensors. A method for detecting obstructions in a filter may also be provided. The method may include: locating a sensor in a zone within a filter; connecting the sensor to a controller; monitoring the sensor with the controller; and determining whether the zone is obstructed based on data received from the sensor.
