Refrigerated dosing using DOS

Really good idea to set the DOS in reverse for mixing and draining the line. For how long have you been running it this way? I wonder how long will the hoses stay clean.
BTW, I wouldn't put money on that being 11ml. Those plastic graduated cylinders that come with the DOSs are a joke. I have 2 and one came 1ml off and the second one 2ml off.
Please keep us posted!
 
Nice job, was curios how you were going to clear the line after but that dose a good job running in reverse. Very cool

What would you use for better accuracy on the amount? I just started dosing fuel this way.

A class 'B' cylinder would suffice, but I'd just go with a class 'A' like this one.
 
For feeding I would not sweat it. I don't think it makes a huge difference if you dose 10 or 11ml.
The problem is when you use it to move large volumes of water like in my case I'm moving 2.7 Gallons every day daisy chaining from the display tank to the frag tank. Those milliliters add up quickly in that case.
I trust the volumetric flasks more than the cylinders. Class A in both cases.

Flask is more accurate and less prone to user error.
