Abstract

Embodiments of the present disclosure include a fuel dispensing apparatus for delivering fuel from a fuel source, and related components, systems, and methods. As fuel is delivered from the fuel source, fuel quality is monitored using one or more fuel quality sensor devices, which detect one or more corresponding fuel quality characteristics. In response to the detected fuel quality characteristics, a visual indication of fuel quality is provided at a visual indication device. The visual indication includes a unique combination of a color component and a frequency component, thereby allowing a user of the fuel dispensing apparatus to quickly determine fuel quality status as the fuel is delivered from the fuel source.

Claims

3. The fuel dispending apparatus of claim 2, wherein the first color component is green, the second color component is yellow, and the third color component is red.

4. The fuel dispending apparatus of claim 2, wherein each of the at least one safe state has a unique flashing frequency component selected from the plurality of unique flashing frequency components with respect to every other safe state, each of the at least one intermediate state has a unique flashing frequency component selected from the plurality of unique flashing frequency components with respect to every other intermediate state, and each of the at least one danger state has a unique flashing frequency component selected from the plurality of unique flashing frequency components with respect to every other danger state.

5. The fuel dispensing apparatus of claim 4, further comprising a plurality of safe states, a plurality of intermediate states, and a plurality of danger states, wherein

the flashing frequency component of a first safe state has a frequency of zero such that the visual indication device is constantly on, and the flashing frequency component of each subsequent safe state has a frequency higher than the previous safe state;

the flashing frequency component of a first intermediate state has a frequency of zero such that the visual indication device is constantly on, and the flashing frequency component of each subsequent intermediate state has a frequency higher than the previous intermediate state;

the flashing frequency component of a first danger state has a frequency of zero such that the visual indication device is constantly on, and the flashing frequency component of each subsequent danger state has a frequency higher than the previous danger state.

6. An electronic control system configured to communicate with at least one fuel quality sensor device of a fuel dispensing apparatus and at least one visual indication device, the electronic control system being further configured to:
