What Is qnl/h and How Do You Convert?


Thread Starter


I have some rotameters on site and I expected them to show l/h, but after looking at them it says qnl/h. It is simply for setting instrument air for purging purposes, but I'd like to understand how to convert this to l/hour. We might not have the required flow of instrument air but I cannot set anything up until I can convert to what the manual is asking for.

Thanks for any help.
