1. A dispensing system comprising:
- a dispensing system reservoir disposed within the dispensing system;
a housing member attached to a first rail and a second rail;
a movable mount configured to move along the first rail and the second rail;
a first electronic sensor comprising a first membrane, wherein the first membrane comprises a first conductive layer disposed between the movable mount and a first dielectric layer, a second conductive layer attached to the housing member, and the first dielectric layer disposed between the first conductive layer and the second conductive layer, wherein the first electronic sensor is disposed between the first rail and the second rail, wherein the first electronic sensor is configured to;
detect a first change in fluid product of the dispensing system reservoir based upon force from the dispensing system reservoir displacing the movable mount along the first rail and the second rail against the first membrane; and
a controller coupled to the first electronic sensor and configured to receive a first signal from the first electronic sensor indicative of the first change.

Abstract
A dispensing system comprises a first electronic sensor and a controller. The first electronic sensor may be configured to detect a first change from a first amount of a fluid product in a dispensing system reservoir to a second amount of the fluid product in the dispensing system reservoir. The controller may be coupled to the first electronic sensor and configured to receive a first signal from the first electronic sensor indicative of the first change. The dispensing system reservoir may be disposed in the dispensing system. A method for determining a remaining service interval for a dispensing system reservoir is also provided.
