Uniweld NV1 NitroVue Nitrogen Flow Indicator
This Uniweld nitrogen flow indicator is nicely made from machined aluminum and is easy to use. It is very compact and uses a simple flow ball with a color scale marked 3-5 SCFH for brazing and yellow for 20+ SCFH for purging. It has built-in 200-psi overpressure protection. I made up a short piece of 3/8” copper tubing with a couple of flare fittings so I could set it up for vertical use for my nitro tanks. I find it great for quick set up when flowing nitro for brazing. No more bulky and fragile nitro flow gauge setup needed for brazing and to get banged around on the job all day long. This little flow indicator seems to be working just fine for my needs.

UNIWELD Quality!
Simply the best. Be sure you have a uniweld regulator with the outlet pointing down. Very accurate and good value for the money!

Does the job.
I really like this but there is one short coming. Not all regulators hang at the same access port orientation. On my rig my flow indicator is not vertical, but more like going from 11 o clock to 5 o clock if you drew a line through them on a clock. Still works, but doesn't hang perfectly. In my case, the pressure regulator (obviously are movable) rotates just so far and hits the tank so it's not possible to get it straight by moving the regulator. I have leaned the nitrogen tank against the side of a house at an angle, and got the flow indicator vertical that way. It's a small thing that doesn't hurt the end result, but a nuisance to me anyway.

Extremely easy to manage and use.
Easy visual indicator and adjustment of flow. Logical placement off bottom of regulator.

Uniweld NV1
The precise metering of Nitrogen should make my tank last forever thus offsetting the initial cost. Appears well made and durable enough to keep loose in the tool box/bag unlike the bulkier ones. It will work well to sweep wet mobile A/C systems next to my high pressure Nitrogen leak down test set-up. A worthy addition.
