How many tanks sensors can be connected to Cerbo Gx from third-party NMEA 2000 tank senders? And if they can be displayed on the GX TOUCH 50 like Bar Graph?

@zygao

A single physical NMEA 2000 network can accommodate up to 50 devices when properly designed and considering the power consumption of these devices (allow for voltage drop).

Physically it makes no difference if they are connected via VE.Can/NMEA 2000 to the Cerbo GX or any other NMEA 2000 device. The only limiting factor (besides the bus speed - 250kbit/s) I can think of is processing power though I'm confident the Cerbo can handle that. But I'll make sure this is correct and come back to you if it's not.

This is how it will look like on a display:
