working principle of pressure transmitter is Hook law

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

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.
