Propeller code for fuel metter

mugur

Hi, i want to buy a propeller just for making a device that will tell me how much
liters of gasoline my car eat's every 100Km.

I have a flow sensor that give me out 1140 pulses (hall sensor inside) for each gasoline liter. I know my circumference of my car wheel.
Can someone help me with a short code that will display the result on 16x2 serial LCD please?

You will also need a sensor on the wheel to count revolutions to get the distance used in your calculations.

mugur,

Depending on the vehicle, you should be able to pick a speed pulse going to the dash. This would the best. It's normally a 0-12v or 0-5v signal and could be read by the propeller.

I've also used the Fuel Injector pulses to keep track of the amount of fuel used.
