Hello everyone, I am new here and just wanted to take this time to say hi. My name is Victor I am an automotive technician from Boston MA, I'm really glad I came across this Forum it has deffinetly peaked my interest. With that being said... I do have a question. I am working on a project which requries 1 psi air pressure. My air source is 125 to 175 psi. So far I have obtained a 0-5 psi air pressure regulator (Dwyer MPR2-0) and can succsessfully set it to 1 psi. However, when my source pressure drops or raises it has a significant effect on my output pressure (+/- 2 psi). Question being, how can I keep my output pressure constant at 1 psi with a variable source pressure?
