Can the hydrogen flow rate be measured using an orifice flow meter?
The best way to measure gases is with a membrane
Standard orifice plates can be used to measure hydrogen, and they work well in my company! But the measurement accuracy seems average!
It definitely can be used; it’s just that there are requirements regarding the flow rate of hydrogen!
Thank you all for your answers:victory::handshake
Hydrogen has requirements regarding safe flow rates. The SHQL series of thermal gas mass flow meters can also be chosen.
Sure, the hydrogen project I’m working on currently uses orifice flow meters, but they are not recommended for pipes smaller than 1".
There’s no problem; it’s just that the precision is a bit low. Generally, achieving precision at level 1 is already very good
It can be used. For the two-stage quench hydrogen flow in our hydrogenation reactors, orifice plates are employed; however, the instrumentation selected must be appropriate, as zero-point drift can be significant at times
Because hydrogen has strong permeability, it easily causes drift
