In my weird on going obsession with CO2 diffusion and measurement, I've decided to try some new methods for both measuring CO2 as well as flow through reactors.

It uses an in line needle wheel pump that dices up the CO2 along with a typical 2" PVC Reactor tube.

The needle wheel grinds up any collection in the top of the reactor tube.
This maintains the pressure inside the reactor tube and creates a mist.
Somewhat like a recirculating skimmer does.

I'll post some pics later.
