What is the difference between a single gauge regulator and a dual guage regulator? I am assuming that a dual gauge regulator has a gauge that reads the pressure in the tank and a gauge to read the pressure exiting the tank? Does a single gauge read the pressure inside the tank or exiting the tank? or am I wrong on all accounts? If I add another gauge to a single gauge regulator, does that make it a dual gauge regulator or is there a difference in the inner workings of the regulators? thanks
