Flow meter

[Llew2_1]

Anyone have a design for a simple flow meter. I have a few thoughts.
1) A transperent tube. with a pingpong ball in it, but how to calibrate it ??
2) Submerse a 1 ltr bottle, in a bucket of water. With the end cut of it and a tube clued in the cap. From the HHO output. Time it takes to blow water out.
Also anyone used a water gauge to measure presure.
Anyone know how much flow meters cost and where to get them ??
thanks

Personally i like the bottle method, cheep and accurate. gas temperature is the main thing that may change results.

You can by a gases flowmeter starting around $40. you'll have to do some conversion and compensation math to give you a good number. Mileage Seekers sell one that has been converted (to a point)
