    Now this I would love to try!

    All the wholesalers around here sell the nitrogen regulators, but I've never seen a flometer before.

    I'm going to make one out of 7/8 with the cap tube inside, that looks like it would work nice.

    Thank You.

    I just brazed a couple of access fittings on a 10 ft cap tube I had laying around.

    Actually, I've tried my "Frankenpurger" for liquid charging and it works pretty good for a smaller systems. I measure the charge rate, but I'd guess about 1 lb/min.

    That's a nice DIY there. I just make sure to take my flow meter off after each use. Haven't broken one in all the years I've been at it.

Size:  135.3 KBI really like Western Enterprises nitrogen regulator (VN-250 or VN-500). It has 3 settings, purge, braze, ans test. I like the fact thats its all in one, and not as cumbersome .
