Abstract

A system, methods, and apparatus for preventing receptacle overfilling are presented. The system can include a sensor member configured to couple with a receptacle and sense a material level within the receptacle, such as via a sight glass of the receptacle. The system can include a controller in operable communication with the sensor member and configured to instantiate the shutoff of material flow from a material dispensing system if a particular material level is detected by the sensor member. The system can include an intermediate member configured to relay communications between the sensor member and the controller. The intermediate member can be coupled to a fluid line and can further act as a holster for the sensor member, such as by facilitating the coupling of the sensor member to the intermediate member and/or the fluid line.

First claim

What is claimed is:

1. A sight glass monitor apparatus, the apparatus comprising:
a support member including a front side and a back side, the support member configured to couple to a receptacle having a sight glass, wherein the support member includes a base portion having an opening extending from the front side to the back side of the support member and allowing a view of the sight glass through the front side and the back side of the support member;
a sensor having a front portion and coupled to the support member; and
a controller in operable communication with the sensor and configured to receive one or more signals from the sensor,
wherein the sensor is configured to detect a level of a material in the receptacle via the sight glass.

2. The apparatus of claim 1 , wherein the support member includes a handle internally hollow and configured to house at least a portion of one or more electronic components associated with the sensor.

3. The apparatus of claim 1 , wherein the front portion of the sensor is positioned to face toward the back side of the support member through the opening.

4. The apparatus of claim 1 , wherein the support member is configured to magnetically couple to the receptacle.

5. The apparatus of claim 1 , wherein the support member further includes a hinged brace configured to abut the receptacle.

6. The apparatus of claim 1 , wherein the opening is configured to allow a view of a sight glass from the front side of the support member.

7. The apparatus of claim 1 , further comprising an intermediate member in operable communication with the sensor and the controller.

8. The apparatus of claim 7 , wherein the intermediate member is coupled to a fuel line.

9. The apparatus of claim 7 , wherein the intermediate member is configured to relay the one or more signals generated by the sensor member to the controller.

10. A method of using a sight glass monitor apparatus, comprising:
coupling a support member including a front side and a back side, the support member to a receptacle having a sight glass, wherein the support member includes a base portion having an opening extending from the front side to the back side of the support member and allowing a view of the sight glass through the front side and the back side of the support member;
coupling a sensor having a front portion to the support member, wherein the sensor is configured to detect a material on the interior of the receptacle via the sight glass; and
receiving, via a controller in operable communication with the sensor, one or more signals from the sensor; and
detecting a level of a material in the receptacle.

11. The method of claim 10 , wherein the support member includes a handle internally hollow and configured to house at least a portion of one or more electronic components associated with the sensor.

12. The method of claim 10 , wherein the front portion of the sensor is positioned to face toward the back side of the support member through the opening.

13. The method of claim 10 , wherein the support member is configured to magnetically couple to the receptacle.

14. The method of claim 10 , wherein the support member further includes a hinged brace configured to abut the receptacle.

15. The method of claim 10 , further comprising an intermediate member in operable communication with the sensor and the controller.

16. The method of claim 15 , wherein the intermediate member is coupled to a fuel line.

17. The method of claim 15 , wherein the intermediate member is configured to relay the one or more signals generated by the sensor member to the controller.
