I have searched this forum and the general Internet via Google and am just getting more confused.
I thought I would build a simple manometer for testing purposes, but am having difficulty finding consistent information.
Here are my questions;
Does the size of the tube matter?
Can a reading in inches be taken directly from either column? Regardless of tubing size?
Is the reading taken from one column only or is it the difference between the two columns?
I have found answers to these questions on several sites, only to find contradictory answers on the next.
I am considering just ordering a Magnehelic or two from E-Bay, but then I have a slew of questions on these also.
It seems like for the price of the Magnehelic, that is the way to go. They can be found so inexpensively, maybe it can still be a DIY project in the assembly and building of the stand etc.
Any and all experience, help etc is appreciated.
