How to calibrate a flow meter?
I have found in the scrap yard, a flowmeter. it produces a voltage the hen I breath in. Have you an idea to calibrate?
Is this for liquid, or for gas?
If for liquid, I would fill up a large reservoir through it, such as a stock tank or small swimming pool.
If for gas, its more tricky. Maybe blow up a big balloon (like a hot air balloon).
I do not know why it was intended (no instruction manual for the things found in the scrap yard)
This is not it. But it is a clue.
Looks like it is probably for liquid, and means something like this.
Hoffer 1 1/2 inch inlet X 1 1/2 Turbine Size - 8 GPM minimum flow - 50 GPM Maximum flow - ceramic hydraulic bearing self lubricating - 1 magnetic coil pickup, 1" MNPT riser- NPT Pipe thread - ???
Wooh! … Excellent deduction, Kyle thank you
It seems obvious now that you have said!
Perhaps that might also run on gas?
What do you think?
I think Steven Abbadas did some work on flow meters on another web sight. I know he is busy teaching now but maybe someone can get his attention. TomC
