Tatsuno Lobe Flow Meter used analog (4 to 20mA) current loop for connection to PC. How to convert a 4 to 20mA to RS232? can be explained with the schematic?

Thank you.
 
In the Tatsuno Lobe Flow Meter Datasheet only contains information that interfacing using 4-20mA current loop, not mentioned there whether

1.Is active or passive side?
2.Is 2 wire, 3 wire or 4 wire?
3.Is half duplex or full duplex?

Does anyone know, Tatsuno Lobe Flow Meter Interface used 4-20mA current loop type what? Thank You.
