gauge selection

If running a system at 65lb, I would be OK with a 0-100lb gauge, correct? Also, it is located on the suction side of a large Cornell pump, and bounces a lot. (old gauge dead) Wouldn't a liquid filled gauge help steady it out?

    I should add that I am wondering what is best for gauge longevity...if running at 65lbs, a 100lb or a 150lb?
    This job has many bad gauges...

    I try to get gauges that are double what the system is running at. I guess a different way of saying that is I want the normal system pressure reading in the middle of the gauge. 0-100 would be my choice if you have a system at 65. 0-150 would be my second choice.

    There are two kinds of liquid filled gauges, those that have leaked all of their fluid out and those that are soon to leak all of their fluid out. I've tried them all, I don't use them anymore.

    If you have a system that has rapid fluctuations, I would look for a "dampened" or "snubbed" gauge. It used to be you could get "snubbers" that you would put between the gauge and the system, but what they amount to is a very small orifice.

    You have a McMaster-Carr catalog, right? If not GET ONE! They have an excellent web site, but I like being able to compare all of their gauges and accessories. They have too many pages of gauges and stuff to list. Try there first, that's where I buy most of my gauges.
