Arduino for current measurment with display

So i builded one 4-20mA Generator. I had one 10VDC Generator and with help of Resistors and Poti i have now 4-20mA Generator. Now i would like to have Display that shows mA (right now i´m using Amp meter between Generator and load). It can be 4x7-segment display or Liquid crystal.

Is that possible? I have some exp with Arduino but I´m no guru.

If you need I can upload schematic of my mA-Generator.
