A flow sensor for sensing flow of a fluidic medicament, the flow sensor comprising:
- a flow tube having an inlet and an outlet;
- a first coupler secured to the inlet of the flow tube;
- a second coupler secured to the outlet of the flow tube;
- and
- at least one absorber sleeve having an inner diameter directly engaged with at least one of the first coupler or the second coupler over the at least one of the first coupler or the second coupler.
A flow sensor for sensing flow of a fluidic medicament comprising:
- a flow tube having an inlet and an outlet;
- a first coupler secured to the inlet of the flow tube;
- a second coupler secured to the outlet of the flow tube;
- and
- at least one sleeve including an absorbing material, wherein the at least one sleeve secures the flow tube to the first coupler and the second coupler, and
