Hi,
I have 5 tanks in the boat.
how can I connect more than 4 resistance measure devices to the Cerbo?

Just in case someone else out there doesn't want to replace their tank probes to get around this problem you can use the GX Tank 140 with your resistive tank probes by converting them to voltage tank probes. You need to make a voltage divider with one of the resistor legs as the sensor. In practice this means you just have to buy a single resistor with a value that you calculate so that the output voltage is between 0-10V. Then program the Cerbo GX with the empty and full tank voltages.

That's not possible. 4 is the maximum number of resistive tank probes on the Cerbo GX.
You could use a GX Tank 140 and with that current sensors (4-20mA) or those with voltage signal (0-10V). Alternatively Mopeka Pro LPG or Water probes via Bluetooth or NMEA 2000 tank senders (requires a N2K network), even resistive and as many as you want.
The VE.Can resistive tank sender adapter could be used but this appears to be very costly, £400 in the UK, more expensive than a Cerbo GX.
