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
