The base houses a controller that generates at least one operation modification signal, and the flow sensor is separable from and mountable onto the base. A bottom surface of the flow sensor housing includes the seal. The seal forms a liquid-tight engagement between the flow sensor housing and the base when the flow sensor is mounted onto the base. ## Claims ### Claim 1 A system comprising: a flow sensor contained within a flow sensor housing; and a base that houses: a controller that generates at least one operation modification signal, wherein the flow sensor is separable from and mountable onto the base. ### Claim 2 (depends on 1) The system according to claim 1, wherein the flow sensor includes at least one sensor to characterize at least one attribute of a fluid from a fluid source, and wherein said at least one sensor is in electrical communication with said controller via a connection between the flow sensor and the base when the flow sensor is mounted onto the base. ### Claim 3 (depends on 2) The system according to claim 2, wherein the controller that generates the at least one operation modification signal in response to the at least one attribute matching at least one condition specified by at least one rule, wherein the flow sensor includes: a fluid port having a flow tube; a fluid inlet at a first end of the flow tube adapted to couple to an outlet of the fluid source; a fluid outlet at a second end of the flow tube adapted to deliver the fluid from the fluid source to a fluid pathway that provides the fluid to a patient;
