Good Evening all.My question is - For a feed water line to
an equipment if i need to measure the flow we will use
orifice /magnetic/vortex depend on cost/spec.If i need to
measure a ''Alarm''signal and ''Interlock'' from one point
i think we can use orifice type in one location with 2
different tapping points - one for alarm and one for an
interlock to flow valve..If in case i need to have both
these signals(Alarm & interlock) from magnetic flow
meter,is it possible??will 2 seperate sensors will be
located inbuilt r we can program it ??..i thk we can have
one transmitter with these 2 signals...need to know any
technical issues are there?pls clarify

If this is not SIS (safety instrumented), the 4-20mA from a
single flow transmitter can feed a separate I/O modules (4-
20in, relay out) an alarm module and a separate interlock
module.
Or, depending on the converter/transmitter model, most
magmeters have at least one assignable relay output, some
have two relay outputs.
I've always used orifice flange unions that have only one
set of taps. There might be a double tap flange unions, or
I suppose you can drill and weld the pipe for taps. But
again, unless this is SIS, why would you? Decisions made
on a 4-20mA flow signal on a PLC?DCS/Controller/I?O modules
can do multiple functions.
If your situation is SIS, you should state that.
