Hi ,
Please explain me 2 wire & 4 wire in more detail , from what i know is in 2 wire the power supply & output like 4 - 20 mA are looped in ,whereas in 4 wire there are 2 wire for power supply & 2 wires for output ,also a second part to my question is when we wish to connect a flow meter to a host system like dcs What are the considerations to be kept in mind while selecting the transmitter , what data we may need from dcs in order to size the transmitter ,
Thank you .
