This is an information post.
If you are needing more than 4 tank inputs, we have tested with 12.
2 x GX Tank 140 and the 4 native inputs.
Our voltage based tank level input sensors are either differential pressure or ultrasonic under tank.
There are also LPG tank sensors that are voltage based. All 12 tanks appear on the Cerbo Tank display. Pic attached.
For fewer that 12 it would be easier to see...Watch video on Youtube search Safiery. Cheers
