If one were to set up a (cheap) mass flow controller

to control a given quantity of gas (air) through a short pipe exposed to the furnace interior and measure temp. in and temp. out you might get a usable system. The air rate would have to be large enough to stop the pipe carrying the gas from melting.


If you are using an inert gas atmosphere (which I consider a near-necessity for a general purpose ultra-hot oven) then you could use molybdenum tubing which is readily available and not too expensive. Mo melts at 2623 C.
