Abstract
An assembly for estimating consumption of a fluid includes a coupling device enabling fluid flow, a carrier assembly slidingly coupled to the coupling device, a biasing mechanism positioned between the coupling device and the carrier assembly, and a displacement sensing mechanism including a sensor coupled to one of the coupling device and the carrier assembly, and a magnet coupled to the other of the coupling device and the carrier assembly. The displacement sensing mechanism is configured to sense a displacement of the magnet relative to the sensor due to coupling of a fluid source to the coupling device.
