Hi All,
An externally powered instrument like ultrasonic flowmeter or coriolis flowmeter operating with 120 or 110 V power supply can be Intrinsically safe certified(EX ia).
If Yes how with model reference
if No, Why??

Repeating same post will not help you in anyway.

You can add the additional details to the already published question using REPLY option.
