[Gasification] Gasifier Bed leve sensor info

[Greg Manning]

Instead of trying to find a sensor that will live at extreme temperatures,
(and will most likely fail at the worst possible time), I would suggest
that concentrating on the feedstock consistency and knowing the incoming
moisture level, this way, you can extrapolate the feed rate from the gas
output and spent char amount.

Some things are better done (also wiser and cheaper) doing it "Old School"

"X" feedstock at "Y" moisture level, with a "Z" level of intake air, will
result in a bed depth of "Q", for a length of time "R", this would mean
that "X" amount of feedstock inputted every cycle of "R" will keep the bed
depth at "Q".

The above equation works for the gasifier I build.
