Dont worry about the Arduino. Its very easy to use and due to its popularity, there is tons of info on the net.

My design is also a "no solder", which makes it very easy to build.

If you eventually try it and need help, just message me.
Was this the one you used? FLOWFUEL30L0 - 2.0 to 30.0 L/min Diesel and Gasoline Flow Sensor

I see it only reads to 30lph. I noticed you thought this would be ok. My 140 four stroke burns about 45lph at full chat, i guess your 2 stroke would burn a fair bit more? Does it read higher or stop at 30lph?
Do you think i could run their digital display on the flow meter while also feeding the Arduino's inputs? I thought it would be nice to waterproof their meter and fit it on the dash. Flow Sensor

Did you order your flow meter direct?

Lastly, will this Arduino board work ok? its a little different to yours... UNO R3 2012 Development Board MEGA328P ATMEGA16U2 With USB Cable For Arduino UK | eBay

Many thanks!

Hi,

I have successfully managed to pass a bit more than 60l/h (water) through this sensor.

When you buy the sensor/meter combo, the manual strangely states 60l/h...

I think you won't have a problem using the Arduino and the LCD.

I ordered mine from the futurlec web site.

Yes its the newest model. The UNO. Mine is old but they are basically the same Layout.

Thanks,
I bought the Uno board.
I also bought the Futurlec Flowmeter with the LCD display, also one spare flowmeter.

I already have what i think is a HC-06 bluetooth module (BC417 chipset) on 3.3v - 6v backboard. Will this work ok?

The HC-06 differs from the HC-05 in that it can only act as a slave, which is OK for this project. Be sure to connect the correct pins though, because there are different versions out there.

You might consider buying a waterproof case for the housing as well.

Simon does your 4-stroke have constant flow or does it send fuel when the outboard needs it?

Flow that is not constant will give inaccurate measurements. You can however overcome that by increasing the delay in the Arduino sketch.

Seems like you are my Beta tester for 4-strokes

Im not sure. How can I tell? All my other engines have been two strokes. The 4 stroke fuel setup seems the same as any other two stroke.
When I turn on the ignition I hear the fuel pump buzzing under the cowl for a few seconds.

To be honest, I don't really know. I have read somewhere that this is the case with some newer outboards.

Anyways, it won't be a problem since we can do any calculations we want with the Arduino.

I will try to find more Info on this.

Hi
I got my Arduino now and having a play.

This is my first time, so please be patient!

I get the following fault when compiling...

BT_Fuel.ino:18:47: error: #include expects "FILENAME" or <FILENAME>
BT_Fuel:19: error: 'SoftwareSerial' does not name a type
BT_Fuel.ino: In function 'void setup()':
BT_Fuel:42: error: 'BTFuel' was not declared in this scope
BT_Fuel.ino: In function 'void loop()':
BT_Fuel:57: error: 'BTFuel' was not declared in this scope

It highlights this line of the code:

SoftwareSerial BTFuel(11, 9); // Define the Pins of the HC-05 Bluetooth device. RX, TX

help!

I might have sorted it. I modified this line. Can you check?

#include <SoftwareSerial.h> // import the Arduino serial library

Yes you did. For some odd reason Copy/Paste didnt work as expected.
