Apparatus and Method to Join a Coupler and Flow Tube in an Ultrasonic Flow Meter

Abstract:

A flow sensor sub-assembly for sensing flow of a fluidic medicament includes 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, a first piezo element secured to the first coupler, a second piezo element secured to the second coupler to define a predetermined distance between the first piezo element and the second piezo element, and at least one absorber sleeve engaged with the first coupler, the flow tube, and the second coupler.
