instrument legend "Mo3" question in the P&ID
(OP)
Dear eng-tips member
I found a "Mo3" (express as middle of three values is used for alarms and downstream function ) located outside of the instrument circle in our project P&ID, but I don't get it why this should be
there, and it seems unnecessary. Could you please give me some
good explanation for this ?
Thank you very much.

I am not a fan of it but if they have the clout to put logic, alarm points, etc. on them, they can knock themselves out. I fought that battle and lost. They didn't even want to reference other drawings on P&IDs. But, I digress into minutia.
