Is there a solvent medium in the pipeline gallery of the tank area? Are the instruments in that gallery explosion-proof?

Excuse me, for the measurement of utility consumption at the entrance to the tank farm utility tunnel, if it is intended to be installed on the tunnel, should the meter used there be an explosion-proof type?
It is necessary to consult the safety and environmental department as well as the designers to find out what zones the pipe corridors for installing instruments are divided into. If it’s just a few water pipes or nitrogen pipelines, then it’s a safe area. If they are all flammable media, then it certainly has to be a hazardous area.
GB50058 determines whether explosion protection is required based on the classification of explosion-proof zones
In hazardous and flammable areas, explosion-proof equipment must be used on-site
