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.

Abstract: Embodiments can detect air in a pumping system. A portion of the system may be isolated from other components located upstream or downstream. The isolated portion may include a chamber, tubing, lines, valves or other components of a pump. In one embodiment, the difference between the starting pressure and an ending pressure taken after a piston has moved a predetermined distance. The pressure difference can be compared with an expected value established for the particular system set up and/or fluid property to detect the presence of air in the system. In some embodiments, a distance between the starting and ending positions of a pump component may be determined after a predetermined pressure difference has been achieved. The distance can be compared with an expected distance to detect the presence of air in the system.
