A system for sensing medicament delivery and transmitting an operation modification signal having at least two separable components is disclosed. The system includes a flow sensor having an inlet to couple to a fluid source, an outlet for delivering fluid from the fluid source to a patient, at least one sensor to characterize at least one attribute of the fluid, and at least one pin in in electrical communication with the sensor. The system includes a second component having a base having a contact, a controller in electrical communication with the contact that generates an operation modification signal in response to an attribute matching a condition specified by a rule, a transmitter for transmitting the operation modification signal to a device, the operation modification signal, when received by the device, causing the device to modify at least one operating parameter, and a cross-component electrical circuit.
