Hi friends!
I need help to make a circuit for synchronizing two signals - fuel level gauge and LPG level gauge in my car. I would like to have an information on the car Instrument Panel for fuel level when I'm driving on petrol and the LPG level when I'm driving on LPG.
The problem is that the fuel level gauge have a resistance form 0 to 285 Ω as follows:
10 Ohms -full
55 Ω - 3/4 tank
98 Ω - 1/2 tankΩ
155 Ω - 1/4 tank
285 Ω - empty
The LPG level gauge have a resistance from 0 to 90 Ohms.
0 Ω - empty
22.5 Ω - 1/4
45 Ω - 1/2
67.5 Ω - 3/4
90 Ω - full
I'm attaching a principal circuit.
Thanks for your help in advance!
