Sensor Calibration

Hello again. I know its been a while, however I was enjoying my long vacations :)
Since I managed to make my BT Fuel manager work with all sensors, I had to calibrate them because for most the datasheet was crap!! So here it is, well an old version of it I think. Don't even know if it is the working one since my device is installed on my boat.

How it works:

The counters start from 0 in the Serial Console.
Connect the sensors and pass a litre of water (gasoline is better, but stick to water) through the sensor.
I did this by connecting a fuel hose to a bottle which hat exactly one liter in it.
After all the water has passed trough the sensor , notice the number of Pulses it registered. Thats your pulses per liter!

Easy!
