Flow element purpose


For electromagnetic flow indicator transmitter , mounted in line , is there a need to use flow element !
any one can tell me when to use flow element and in which case ?

The magnetic flow meters have inbuilt electrodes to sense the flow. They don’t need any separate flow element.

What flow elements you are talking about here?

In P&ID they have put FE associated with electromagnetic flow instrument
Another question , does electromagnetic flow instrument can be equipped with flow totaliser !

yes, some have inbuilt totalizers, ask OEM

thanks a lot
