NMEA2000 fuel sender with Raymarine MFD

[Cardo]

I've recently fitted an Offshore Systems NMEA2000 fuel sender (http://www.osukl.com/3271.htm) to my tank and hooked this up to my SeatalkNG network with the adapter cable. That part was easy, and my e7 chartplotter picks up the data no problem.

The issue is my tank isn't rectangular, so it doesn't empty uniformly. I had hoped there would be some way to calibrate the sender (aside from empty and full) so I could at least set the 25%, 50% and 75% levels to something approaching accurate readings, but neither the sender nor the e7 appear to have anything like this type of customisation. The sentence "Raymarine MFD users can now calibrate their fuel tank levels" from Raymarine's page - http://www.raymarine.com/news/mynews.cfm?story=5756 seems to be a complete load of tosh, as far as I can tell!

I know the sender can be calibrated (at the factory, or using a likely expensive box) to accurately report the volume of fuel remaining, but I didn't opt for this as I was happy just to have a basic % readout.

Does anyone know if Raymarine have hidden the ability to customise the fuel readout somewhere silly, or is there some other trick to tweaking the data? At the moment we've had to make a little card telling us what the % on the plotter are in reality!

Reading the blurb on the website for the sender it sounds like you can calibrate the sender?

The 3271 can be programmed with up to 100 volumetric points so that it offers the most accurate indication of the remaining VOLUME of fuel in the tank. This volume information can then be displayed on any NMEA2000® enabled display wherever it is required.

I'm interested as I have an e7 and I'm not using half the functions. I want to use it more like an FMS than jut a chart plotter as it has that capacity.

I've been in touch with Offshore Systems who said they'd be more than happy to calibrate the sender if I were to get it to them. They said they only need a day to do it. But seeing as we're currently out in Spain and I've only just got the thing put in, I don't really want to send it back! We'll be going back to the UK in due course, so I'll get it done properly then, but I was hoping the e7 might have been able to do some calculations itself in the meantime, but it seems not. I'm also rather disappointed with the Fuel Management feature. Unless you have an engine which provides its data to the network (generally mobo's), then it's pretty much useless.

Hi Buddy, I've got the same sender on my Rib, I'm interested to know did you ever get it calibrated ?

Not yet, we're not back in the UK until next autumn! But for you it should be an easy trip to their office to get the sender calibrated, you just need your tank dimensions.

They are fitting a new sender this afternoon, we let you know how I get on.

I have Raymarine mfd and digital indication for fuel .my tank is rectangular .please can you help me with informations how to have fuel indication on my mfd
