Abstract
Embodiments herein relate to multi-zone filtration monitoring systems and methods. In an embodiment, a filtration monitoring system is included having a plurality of filtration housings, a plurality of filter elements associated with the filter housings, a plurality of wireless communication tags associated with the filter elements, a plurality of zone antennas, and a wireless communication reader in wired communication with the plurality of zone antennas. The reader can be configured to wirelessly send data to and receive data from the wireless communication tags via the zone antennas. Other embodiments are also included herein.
Claims20
A filtration sensor system comprising:
- a plurality of fluid filtration housings;
- a plurality of fluid filter elements associated with the fluid filtration housings;
- a plurality of wireless communication tags associated with the fluid filter elements;
- a plurality of zone antennas configured to cover different spatial zones;
- and
- a wireless communication reader in wired communication with the plurality of zone antennas, the wireless communication reader configured to wirelessly receive signals from the wireless communication tags via the zone antennas;
- wherein the system is configured to store zone association data, the zone association data including unique tag IDs and zones the unique tag IDs have been located in.
A filtration sensor system comprising:
- a plurality of fluid filtration housings;
- a plurality of fluid filter elements associated with the fluid filtration housings;
- a plurality of wireless communication tags associated with the fluid filter elements;
- a plurality of zone antennas configured to cover different spatial zones;
- and
- a wireless communication reader in wired communication with the plurality of zone antennas, the wireless communication reader configured to wirelessly receive signals from the wireless communication tags via the zone antennas;
- wherein the system is configured to identify a filter cleaning event by observing a filter element exit and then reenter a zone followed by observing a pressure drop that is less than it was prior to the filter element exiting the zone.
