How Can I Build a Simple Water Manometer (and test fans with it)?

Holy crap, manometers are expensive AND most are not made for fan testing, especially at low pressure (according to manufacturers I've asked), or else they require a special dual-chamber testing unit, which is massively expensive to buy.cooling-fan-double-chamber-measuring-dev

I'm sure LonGwin (yes, that's how THEY type it, which makes sense since it's a Chinese, not American, company) has something like that.

A simple water manometer, Yellow Jacket 78075 Water Manometer Made of a Durable Plastic, is $56!

So, given that I'm horribly short on space at this point, and I'm going to have a 33" long noise-dampening chamber on my table, I don't need another box on top of that, so I want to make my own water manometer. Can anyone tell me how or point me to the clearest possible instructions on how to make it cheaply with plastic (cuz I'll definitely break it if it's glass)?


Thank yoU!

Fantastic! That's a great guide, and I can't imagine that it'll cost much money.

How do I connect the fans? I assume I'll need a frame and a reducer of some kind. There's the added complication of open/closed chassis, in the worst sense for open where it's not a perfect square but has lobes for the corners and a round frame. I think I'm also going to need some way to ensure that the reducer doesn't distort the results. Suggestions?
