General Info: Fuel Sensor in Lagoons -> NMEA2000

[Whomda]

On my Lagoon 400, fuel levels are read on the proprietary Lagoon panel. I'd like to get the fuel level information on the NMEA 2000 bus so I can read it on the plotter display and on the tablet/PC.

Does anyone know how to augment the sensor to report on NMEA 2000 as well as the Lagoon panel?

The factory sensor (pic attached) is not a known brand or interface as far as I can tell. And i cannot adequately trace the wiring to see where the sensor leads go (there are 3).

(seriously, can any trace the crazy factory wiring in a Lagoon? i love that it's all solidly protected and held in place, but there are amazing amounts of unused wiring running about).

On the latested 400s2 the panel is a Mastervolt MasterView Easy.

Really? i thought only the Battery info was displayed in the Mastervolt display?


FYI I'm not a fan of the Mastervolt display either, since it's small font cannot be adjusted, and Amp usage doesn't go to the 2000 bus. But at least the voltage automatically goes on the NMEA 2000 bus, since the bus detects the voltage of the main bank directly.

Sorry, Correct the fuel levels are in the LCD of the electrical panel.

Right. I'd like to read them in other, much more useful locations.

The B&G displays will do a number of useful things, like set an alarm on low fuel levels, and I think calculate mileage, if only they could get the fuel level info on the NMEA 2000 bus.

Whomda,

I realize this may only be a last resort consideration, but CruzPro makes many gauges you can add to a NMEA network (their gauges are 0183 so you need a multiplexer...)

Here is the link to their fuel gauge that can be calibrated to very accurately plot fuel consumption information as well...

In case this is of interest.

Cheers!

See here.
To calibrate, the best would be to have the display of Maretron too.

The Lagoon (Bavaria, etc) system for measuring and indicating liquid levels is poor. Why use a screw with a wire at linear measurements when the tank is not symmetrical? That can show a 350ltr tank as 1/4 full when there is only 20ltrs left. I have said this before but this is the superior method of measuring fuel/water/waste:

Works very well and can be calibrated to any tank size and shape! I use on my black water, diesel and water tanks. You need to have this for output. It is color, linear or circular gauge, high/low alarms:

Excellent for liquids info to the nearest 5 ltrs and battery monitoring with a shunt.

Thanks all for the replies.

It seems clear I can replace the tank sensor with one that is Ultrasonic with a NMEA 2000 output and get what I would like (with more accuracy), though there doesn't seem to be a good way to get NMEA 2000 AND keep the Lagoon LCD display. Also, sounds like calibration will be an challenge.

I appreciate it.

I just left the Lagoon system as is and added the BEP. Great especially for electric info.

As I did 2 fuel, 2 water and 2 holding I bought the programmer unit and set each ultrasonic unit up for the tank shapes and capacities. Fairly easy to do. Then the electrician just wired them into to BEP display.

That looks pretty great, I will definitely look into that solution.

Good to know you can just add the second sensor to the tank. Looking at the tank, it wasn't obvious how to add a second sensor.

Lagoon installed the Mastervolt Shunt, seems like the BEP solution would mean that shunt would have to be discarded or at least duplicated. unfortunate extra expense, but the Mastervolt Easy View I find to be lacking in usefulness.

Also, do you really have a 400 liter fuel tank on each side?? Very jealous of that.
