Hi there. What is the best way to fill a water u-tube manometer without getting darn air bubbles and if you get them what's the best way to get rid of them!

I use a syringe with a needle you have to go slowly to fill U tube manometer. I have not had problems with air bubbles since I start using the syringe. I bought my syringe at the local drug store
it will hold 60cc.

Thanks Malvin. I have been trying it without the needle and this has been trapping the bubbles. Brilliant idea!
