Mopeka LP Tank Sensor - Australia

HI All, I’m looking for advise/confirmation on your configuration of LPG tanks specifically for Australia.
I’ve configured my as follows:
Capacity - 17L
Sensor value when empty: 0cm
Sensor value when full: 26.4cm

For the full level what I did was fill the tank and then incrementaly lowered the setting until the sensor reading just dropped <100%.
