Abstract

The disclosure describes systems and methods relating generally to filtration. Even more particularly, this disclosure relates to controlling the operation of a pump using filter information. A removable filter can include an electronically readable tag storing filter information. The filter information can be read by a tag reader and rules applied to the filter information to determine whether or how to operate a pump.

Claims

1. A pump comprising:

one or more motors to draw fluid into an inlet of the pump and dispense fluid from an outlet of the pump;

a connection for a removable filter so that the removable filter can be placed in a fluid flow path between the pump inlet and the pump outlet;

an electronic tag reader positioned and configured to read filter information for the removable filter from an electronic tag on the removable filter when the removable filter is connected to the pump;

a pump controller configured to;

receive filter information for the removable filter from the electronic tag reader; and

apply one or more rules to the filter information to determine if the removable filter connected to the pump is an appropriate filter and, if the filter is appropriate, to determine further operation of the pump including how to prime the removable filter connected to the pump in preparation for dispense cycles.

2. The pump of claim 1, wherein the pump controller is further operable to access a first priming routine associated with a first filter type and a second priming routine associated with a second filter type, wherein the pump controller is configured to apply the one or more rules to the filter information for the removable filter to prime the removable filter connected to the pump according to the first priming routine or the second priming routine depending on whether the removable filter is the first filter type or the second filter type.

3. The pump of claim 1, wherein the electronic tag reader comprises an RFID reader.

4. The pump of claim 1, wherein the filter information comprises a part number.

5. The pump of claim 4, wherein applying the one or more rules further comprises comparing a received part number for the removable filter connected to the pump to an expected part number to determine whether to prime the removable filter connected to the pump.

6. The pump of claim 1, wherein the connection comprises a quick change mechanism for connecting the removable filter to the pump.

7. A pump comprising:

one or more motors to draw fluid into an inlet of the pump and dispense fluid from an outlet of the pump;

a removable filter in a fluid flow path between the pump inlet and the pump outlet, the removable filter having an electronic tag storing filter information for the removable filter;

an electronic tag reader positioned and configured to read the filter information from the electronic tag;

a pump controller coupled to the electronic tag reader, the pump controller configured to;

receive filter information for the removable filter from the electronic tag reader; and

apply one or more rules to the filter information to determine if the removable filter connected to the pump is an appropriate filter and, if the removable filter is appropriate, to determine further operation of the pump including how to prime the removable filter connected to the pump in preparation for dispense cycles.

8. The pump of claim 7, wherein the pump controller is further configured to access a first priming routine associated with a first filter type and a second priming routine associated with a second filter type, wherein the pump controller is configured to apply the one or more rules to the filter information to prime the removable filter according to the first priming routine or the second priming routine depending on whether the removable filter is of the first filter type or the second filter type.

9. The pump of claim 7, wherein the electronic tag reader comprises an RFID reader and the electronic tag comprises an RFID tag.

10. The pump of claim 7, wherein the filter information comprises a part number.

11. The pump of claim 10, wherein the applying the one or more rules further comprises comparing a received part number for the removable filter to an expected part number to determine whether to prime the removable filter.

12. The pump of claim 7, wherein the pump controller is configured to apply the one or more rules to information specific to the removable filter to determine further operation of the pump.

13. A method of controlling operation of a pump comprising:

connecting a removable filter having an electronic tag storing filter information for the filter to a pump;

reading the filter information for the filter from the electronic tag with an electronic tag reader;

communicating the filter information for the filter from the electronic tag reader to a pump controller coupled to the electronic tag reader; and

applying one or more rules to the filter information to determine if the removable filter connected to the pump is an appropriate filter and, if the removable filter is appropriate, to determine further operation of the pump including how to prime the removable filter connected to the pump in preparation for dispense cycles.

14. The method of claim 13, further comprising storing a first priming routine associated with a first filter type and a second priming routine associated with a second filter type, wherein the one or more rules are applied by to select from the first priming routine or second priming routine depending on whether the filter is of the first filter type or the second filter type.

15. The method of claim 13, wherein the one or more rules are applied by a system in communication with the pump controller.

16. The method of claim 13, wherein the tag is an RFID tag and the electronic tag reader is an RFID reader.

17. The method of claim 13, wherein applying one or more rules to the filter information comprises comparing a part number in the filter information to an expected part number to determine if the part number in the filter information matches the expected part number.
