Hi,
Is it now possible to use multiple Cerbo GX or Ekrano's in a network and share their data on fx. NMEA 2000 bus?
I have 6 tanks but Ekrano only got 3 tank sensor inputs. Adding a Cerbo GX would give another 4 tank inputs - cheaper than buying 3x VE.Can tank sensors and more "integrated"
Or does anyone know of a 3-4x resistive tank sensor compatible with Ekrano?
kind regards

Why not use a GX Tank 140, which gives you 4 extra tanksensor inputs?
It’s USB powered, and works with sensors giving 4-20mA or 0-10V signal.
Take a look at https://community.victronenergy.com/questions/108147/can-someone-tell-me-about-resistance-based-sensors.html
You can use resistive sensors with 0-10V input or 4-20mA input!
You just need to add suitable resistors.
Kind regards

1. It is EURO sensors so 0 to 180 ohm - so you would probably need to do more than single resistor to stay reasonably precise.
2. You would need to provide a stabile power supply or your readings would vary with battery voltage. So another complexity issue.
But I think I found a solution as it turns out WEMA (sensor makers) actually now makes a 4-6 tank N2K resistive converter for less than £200! (Vs. 1 VE Can converter for £350)
I had been looking everywhere and found nothing for ages...
The GX Tank 140 has two 24V outputs so might work for you!
Kind regards
John
Hi @kaz911,
Using multiple GX devices for their additional inputs is possible - see here for the documentation on how to do it - https://www.victronenergy.com.au/media/pg/Cerbo_GX/en/connecting-supported-non-victron-products.html#UUID-9768e78d-bcfc-f391-52ce-b3dbbdc973ae
I recommended this to a boatbuilder once, but will never do it again. Its better to then replace the tank senders for another type. More work, I know, but more simple system in the end.
thanks all. I think I'll put the WEMA N2k tank readers in :)
