Size: 1/4" NPT (MF5706)
falsely advertised as NPT threads. these are **not** NPT (national, U.S.) threads, these are BSPP (British standard) threads. this means you will have to buy a convoluted set of BSPP to NPT adapter fittings and special hard-to-find size of zinc/rubber crush washers because BSPP is weird -- you cant simply put teflon tape like NPT. honestly, this was a real pain in the ass and wound up costing an extra $60 bucks plus downtime of a week to be fair, once i got it connected finally, it works well enough. But I've no idea for its accuracy, though, as there is no calibration informatino whatsoever. However I knew this coming in, i mean it's a battery operated portable meter from china, less than 200$ so you get what you pay for. Compare Dwyer/Omega's version is $1400. anyhow, i probably would have given it 4 maybe even 5 stars if it had at least been advertised correctly, but the whole hassle with converting BSPP to NPT put me off.

This is a great flow meter to measure compressed air, nitrogen, oxygen, or any other gases. This meter is easy to install and monitor for leaks or system maintenance. Very accurate as this is lab graded. LCD is large and easy to see, and the display rotates for easy viewing from different angels. Price is reasonable for a good flow meter, so great deal. Very happy with this meter.
