how does a bubbler level system work? | Futurist Transhuman News Blog

We have a tank with oil waste that uses a bubbler to indicate the level and to activate a pump to lower the level when it reaches a certain level.

It isn't working, but I do understand the principle of its operation.

Google brings up articles on water fountains, not level detectors.
