I just guesstimate an amount after the noise stops: x time pouring,  
and visual of how much is being added, looking at the can before and  
after. Based on experience. And check my experience with a finger in  
the tank, where there isn't an undercover.

About 2 cm, enough to get below the slot for the tube/probe assembly,  
plus a bit so it doesn't wick up through that hole. Dare? Heck, I  
once ran it clear to the top, not thinking about that little slot.  
And found that the water dripped out, so I wasn't ahead any <G>.  
What's a wee bit of water on the carpet in a faculty office? Nobody  
will ever notice.
