I've no idea how the current
. I assume they are a analogue float type sender and that the water tank gauge in the fuse cabinet is calibrated to that?
I have 4 fresh water tanks (2/side) and 2 gauges on the digital display which isn't super accurate. Would it not be easier to convert the signal already coming from the tanks to nmea2000 and add it to the backbone to be viewed on the Zeus MFD?
I see in the CCGX manual that it supports nmea2000 tank sensors so maybe this is simpler?
ps, i've got the CCGX and it's a great bit of kit, I can spend far too long looking at it tho
