A filtration system comprising: a housing comprising a fluid inlet and a fluid outlet, the housing defining an internal volume; a first filter element configured to be removably disposed within the housing ; a short-range wireless communication tag associated with the first filter element ; a short-range wireless communication reader associated with the housing , the reader configured to wirelessly send data to and receive data from the short-range wireless communication tag when the short-range wireless communication reader and the short-range wireless communication tag are at a distance that is less than or equal to a maximum communication distance; wherein removal of the first filter element from the housing causes movement of the short-range wireless communication tag away from the short-range wireless communication reader by an amount that causes the distance between the short-range wireless communication tag and the short-range wireless communication reader to exceed the maximum communication distance, and wherein the filtration system further comprises a system controller configured to receive electrical signals from the short-range wireless communication reader, characterized by the fact that the system controller is configured to identify ON-OFF-ON patterns in the electrical signals received from the short-range wireless communication reader; wherein detection of an ON-OFF-ON pattern is counted as a filter element removal or a filter reinstallation event; wherein the OFF phase of the pattern corresponds to periods of no communication between the short-range wireless communication tag and the short-range wireless communication reader and the ON phase of the pattern corresponds to periods of communication between the short-range wireless communication tag and the short-range wireless communication reader. a housing comprising a fluid inlet and a fluid outlet, the housing defining an internal volume; a first filter element configured to be removably disposed within the housing ; a short-range wireless communication tag associated with the first filter element ; a short-range wireless communication reader associated with the housing , the reader configured to wirelessly send data to and receive data from the short-range wireless communication tag when the short-range wireless communication reader and the short-range wireless communication tag are at a distance that is less than or equal to a maximum communication distance; wherein removal of the first filter element from the housing causes movement of the short-range wireless communication tag away from the short-range wireless communication reader by an amount that causes the distance between the short-range wireless communication tag and the short-range wireless communication reader to exceed the maximum communication distance, and wherein the filtration system further comprises a system controller configured to receive electrical signals from the short-range wireless communication reader, characterized by the fact that the system controller is configured to identify ON-OFF-ON patterns in the electrical signals received from the short-range wireless communication reader; wherein detection of an ON-OFF-ON pattern is counted as a filter element removal or a filter reinstallation event; wherein the OFF phase of the pattern corresponds to periods of no communication between the short-range wireless communication tag and the short-range wireless communication reader and the ON phase of the pattern corresponds to periods of communication between the short-range wireless communication tag and the short-range wireless communication reader. <EOS>
