Can we inform others of the geopolitical region that this question would pertain to?

Can we use sentences with capitals and punctuation?

Semi-sarcastically,

What is its certification marking?

Usually, the only installation permitted in Zone 0 is EEx ia or other specially certified for use in Zone 0.

Where is the certificate?

Why is 120VAC required in Zone 0? Think about it.

Zone 0 - where "a potentially explosive atmosphere is more-or-less continuously present under normal conditions".

120VAC....

Hmm..........................

Please make sure all CR4 readers are at least 5km away before energising.

What does the flowmeter data sheet and associated certificate say (the things you must look at and fully understand if you are involved in selection or installation of such devices in hazardous areas).

Short answer, no.

Chose something else. Something that is suitable for installation in Zone 0 as part of an EEx ia installation. Otherwise, the individual responsible for reviewing and approving the design simply won't do it!

The problem with questions like that posted is that it shows that the original poster is insufficiently trained to carry out the task.

Do not attempt the installation, modification, energisation, testing or commissiopning of anything involving hazardous area electrical equipment in zoned areas without having received the appropriate training.
