This wiki has been updated 11 times since it was first published in November of 2018. If your work requires you to use nitrogen, having a flow meter installed on your tank is a great way to save some money. These indicators let you know whether gas is moving through the line, often via the use of a levitating ball, a pressure gauge, or other visual cue. These options are simple to use and reliable, making them must-haves for welders, HVAC technicians, and more. When users buy our independently chosen editorial recommendations, we may earn commissions to help fund the Wiki. Skip to the best nitrogen flow meter on Amazon.

Editor's Notes

April 12, 2019:

One of the most important things to think about while you're doing your research is whether you want a basic gauge, a floating ball, or both. The gauge is more accurate, and is likely something you're already used to. The ball, on the other hand, makes it much easier to immediately see whether gas is moving through the line, even if you may not know exactly how much is flowing at the time. Obviously, a unit with both gives you the best of both worlds, but you'll likely pay more for the privilege, and you may find yourself only using one of them anyway.

Also, you should consider whether you're going to pair your indicator with a regulator, and if so, whether you want a hybrid model. We're fans of the Western Enterprises VN-500, as it's versatile in addition to being easily portable and extremely durable.
