I need to connect a pressure, temperature transmitters (4-20mA 24 VDC, Yokogawa transmitters) to Flow computer (OMNI) which is 2.5 Kms distance apart. Can anyone suggest whether it is possible and how?

Regards,
Rajiv
 
Calculate the wire resistance for that distance and make sure the power supply has enough voltage to drive the current through that resistance.

All major brand transmitters have a chart in the manual showing what voltage vs resistance.

Look into suitable cable specification to meet the requirement. Keep Carl's input in mind.
