Update: I have tested the new sketch with two sensors! Working like it should! The best part is that it works, even if you have just one sensor connected.

So one sketch for both situations (Single engine and twin engine)!

Grab the code here.

Run into an issue. Seems like the futurlec sensor does what it says one the box! 30l/h which isn't enough for my outboard.

Luckily I received the 3/8" one a couple of days ago. Going to test it this week.

If making this up for a diesel inboard would you need to fit a second flow sensor on the return fuel line and have a bit of software to do a calc of sensor 1 minus sensor 2 ?

Could it also be made to be connected to a nmea 2000 network?

Yes. Look at some earlier post for the answer.

with your arduino onboard and a CAN-BUS shield you should theoretically be able to broadcast fuel rates to your nmea2000 network (PGN 127489 field 6)
Information is sparse, some chap has already done it despite closed-source NMEA2000 (see below) but not released code...unless someone asks...allen652 or coryjfowler on arduinoforums

I'd be interested in contributing to this if time permits. The resources I have collected so far are:
Arduino CAN-BUS shield using MCP2515:
https://www.sparkfun.com/products/10039

Users who have successfully broadcast PGN 127489:
NMEA 2000 Shield - Arduino Forum

MCP2515 arduino library:
https://github.com/coryjfowler/MCP2515_lib

just need to find time to tie it all together

It's possible. It's easy to do with some shields already mentioned.
However, this project is about sending the data to an Android phone wirelessly.
Anyone is free to use the code for the Arduino.
But NMEA uses wires...and I don't like them much.

Simon666 have you received your sensors? If I am not mistaken, you also got the set with the meter. Can you confirm that the manual states 60l/h instead of 30l/h?

Hi.
Yes I bought one sensor and one sensor/digital display combo.

I cant remember exactly what the flow figure was but it was higher than 30l/hr.
I'm away from home at the moment, but ill check tomorrow when I get back.

interestingly the sensor connect to the display did look very slightly different to the other sensor.
The wire comes out in a slightly different position and is potted in a resin.

the weather looks good this weekend so I hope to get down to the boat.

Hope you do better.
Fingers crossed!

P.S. Can you take a pic of the two sensors side by side when you get back?
