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

Answer Posted / thiagaraj

@CARL ELLIS.. Thanks for your response.In case of using
Alarm (or) Interlock it was a normal practise that we
use ''LOW''LOWLOW'' (OR) ''HIGH''HIGHHIGH'' signal in the
same instrument(orifice etc)..If i need to
use ''LOW''HIGH''LOWLOW'' in the same Instrument is it
possible to use these 3 alarms in a single instrument(flow
transmitter )..If yes is it can be used in Magnetic flow
meter ..pls state its advantages and disadv also.pls clarify

We Have Two Field bus Pressure Transmitters of Different Sensor Range (I.E One is of Lower range and Another is of Higher Range).Is same Process Line. My Question is Can i provide Saturation Limit to my field Bus Transmitter as We can provide Saturation current limit to HART Instruments. As During Low Pressure Both Working OK ,But During High Pressure, transmitter with Lower sensor range Goes to Fault mode as Beyond its Sensor Limit it can Measure, So may I provide Saturation point Some where to Suppress This Fault during High Pressure.
