Big bubble forming in doser to reagent tube??

[Mortie31]

The Teflon tubing wasn’t suitable, too rigid, I have now gone for 7mm o.d. And 4mm I.d. Silicon tube and the bubbles are forming far less, and so far I’ve had no bad readings in the last 10 days. Is does seem to be the thicker wall that as previously suggested may reduce/ stop the bubbles

I think I found the right tube... but I need one more week of testing but haven't seen a bubble for 1week and a half.

Ok, I'm testing a tube that comes with industrials detergent dosing pumps(my company sells sells this so I grab a piece of tube to test)

The only indication I see writen on the tube is "REHAU RAU-PE"

The tube is semi-rigid but fits well in the doser and KHD so... it works for me... checked today still no bubbles.
