Abstract
One or more techniques and/or systems are disclosed for providing level sensing of a fluid in a dispenser canister. The sensor includes a housing having a fluid cavity configured to receive a fluid therein, with the housing having an open end and an opening in a wall opposite the open end. The sensor has a diaphragm coupled to and closing the open end of the housing and a sensing device having a sensing end. The sensing device is coupled to the housing with the sensing end extending into the opening of the wall of the housing, thereby not making direct contact with the fluid.
