A second novel point is that the balls bounce against an aluminum screen, making a distinct noise, an audible sound that the driver can hear. Similar to a popcorn and/or a rattling noise, that allows them to hear liquid flowing. There has never been a product with an audible response in the industry. While unloading at night or in inclement weather, being able to hear and knowing that the fuel is flowing is an incredible safety feature.

The driver can see the balls bouncing, due to they are a different color than the product. While they are bouncing, they are making this very unique sound, a rattle and/or tinkling noise that is never before heard while moving liquids. This alone is a novel invention that has never been introduced before. Audio and visual of liquid flow from a transport tank.
