VDO Freshwater Level Sensors, 4-20mA

The output pins of VDO freshwater sensor must be connected in parallel with a resistor (R=100 Ohm or R=500 Ohm), see attached picture. The resistor has to be connected in parallel to one voltage input on shunts (SC303, SC503, ...) or ST107 SCQ25T.
The measured voltage range (voltage drop on resistor) is calculated with formula U=I*R:
R=500 Ohm:
I=4mA -> Umin=2V
I=20mA -> Umax=10V

R=100 Ohm:
I=4mA -> Umin=0.4V
I=20mA -> Umax=2V
