How to choose the working fluid for a U-tube? What is the working fluid used in U-tube pressure gauges used in general electrolyzers?
Water is generally used...
It depends on how much work pressure you have.
Hehe, here we have the crankcase pressure of the main diesel engine – it’s 5 water columns. It’s difficult to read the value on the gauge, so we made a U-shaped tube out of transparent plastic to help indicate the value. Find a colored marker, put it in water and stir it around to add some color, then pour it into the U-tube, hehe. . . It works. This is my personal opinion for reference only.
