Tzt3 two fuel tanks

[Team TDII]

Hi

I have a problem with tzt3
I have 2 Suzuki 140bg outboard and two fuel tanks.
My problem is, I can’t make two separate fuel tank on the tzt3?????

When I choose two outboard on the tzt3 it shows 2 tank,but same name, and when I add some fuel, It put it on both fuel tanks.

My fuel tank does not have any sensors on!
Both displays from the zuke is connected to the nmea2000 backbone

Any ideas ????

Are you using "Manual Fuel Management" or trying to display an actual tank reading? You have to have sensors on the tanks if you want actual. Otherwise as far as I know, there is no provision for have two tanks when using manual fuel management.

I have a somewhat similar situation in having port and starboard fuel tanks and twin engines, each of which normally uses one of the tanks. The manual fuel management will show the tank level declining based on the total consumption of both engines as though I had a single tank. It is quite accurate although there are small differences from the actual tank level readings (I have sensors on my tanks and analog fuel gauges). This is to be expected because there is a slight difference in the fuel rates of the engines when running and also the generator shares one of the tanks.

You need sensors that can create NMEA 2000 tank level data on the network if you want to show individual tank data.

By the sound of it, the tank sensor infomation is not properly instanced by NMEA 2000 standards. If coming from diffrent tank devices, the NMEA 2000 device instance must be setup with diffrent numbers so they don't conflict. If both tanks are coming from a single sender device (ie interface/gateway), then that device must have the DATA Instances properly configured so that your tanks are not showing up as one tank. The TZT3 can only display what it is being told by the other device(s).
