Diaphragm seal

[Indy]

Hi,
With regards to methanol, is it normal practice to install a diaphragm seal between the process connection and a pressure gauge?

Thanks

Yes, if/when the bourdon tube breaks, you don't want a loss of primary containment of a highly flammable liquid.

Good Luck,

Thanks for the reply. I also thought it would be required. I have been reviewing a specification that says NA for diaphragm seals.

Thanks

Is it water or some other non-hazardous service?

He said methanol.

Good Luck,
