Ok, this is worth a try out.
So what's the math here?
Say the sensor reads, 5000 ppmv in this drop checker.
I have to do 5000 x 0.8317 = 4158.5 ppmv? Then do the math to convert to ppmv to ppmw if I want. If that's the case I might have to do this to my current set up since it's a drop checker as well.
This design solves the ugly box in the tank problem
The benefit with the membrane solution is you can place it different parts of the tank and measure the difference in 3D. I guess with this design it's the overall concentration of the liquid or in 2D (the surface of the water line).
