Hi all, I have a microbush of 8 trees on buckets and always measure how much sap I get from each tree, each collection, so I know which trees are the best producers. And then I have an accurate record of how well they have run over the years.

But the system I use for measuring sap is very, very slow and time consuming....measruing to a fill line.

I need something like a funnel with a digital gauge built into it so I can just pour straight from the pail into the water containers that I use for collecting tanks.

It would also be nice if this device was also either a simple DIY, or is at least affordable and doesn't cost hundreds of $$$, and of course accurate and easy to clean and maintain.

Any ideas? What do other small producers use?
