Dear flow meter, I read my own message this morning and found a mistake. For the US, the meter falls under part 18 assuming that is DOES intentionally generate RF energy for the purpose of mechanical vibration, ionizing gases, accelerating particles etc.. In my experience with a flow meter, this was the case. Otherwise, assuming that it is exempt from part 15, you are only required to hand it over to the FCC if they ask for it and cease operation if notified by the commission that it is causing harmful interference.
