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.
Claims19
A sensor for detecting a level of a fluid in a dispenser container, the sensor comprising:
- a housing having a fluid cavity configured to receive a fluid therein, the housing having an open end and an opening in a wall opposite the open end, wherein the housing comprises an upper housing and a lower housing;
- a diaphragm coupled to and closing the open end of the housing, the diaphragm having an edge, wherein the edge of the diaphragm is sandwiched between the upper and lower housings;
- and
- a sensing device having a sensing end, the sensing device coupled to the housing with the sensing end extending into the opening of the wall of the housing.
A fluid dispensing system comprising:
- a dispenser canister;
- a tube elbow coupled to a bottom of the dispenser canister;
- and
- a sensor coupled to the tube elbow, the sensor comprising:
- a housing having a fluid cavity configured to receive a fluid therein, the housing having an open end and an opening in a wall opposite the open end;
- a diaphragm coupled to and closing the open end of the housing;
- and
- a sensing device having a sensing end, the sensing device coupled to the housing with the sensing end extending into the opening of the wall of the housing.
A method for level sensing of a fluid in a dispenser container, the method comprising:
- assembling a sensor with a housing having a fluid cavity configured to receive a fluid therein, the housing having an open end and an opening in a wall opposite the open end wherein the housing comprises an upper housing and a lower housing, a diaphragm coupled to and closing the open end of the housing wherein an edge of the diaphragm is sandwiched between the upper and lower housings, and a sensing device having a sensing end, the sensing device coupled to the housing with the sensing end extending into the opening of the wall of the housing;
- and
- configuring the sensor for removable coupling to a tube elbow of the dispenser container.
