Hi to all,
I have (like as a lot of other ppl) car with gasoline/gas reservoars. Now anyone know about issues for gas tanks (butane-propane). If you want to see gas level you need to take a look on mechanic meter placed on reservoar.
So I would like to make electronic MCU (STM32 device) controlled or whatever gas level tank meter which output (LCD, LED display) will be mounted easily on driver dash board.
Anyone can some ideas what to use as sensor for measuring level of gas. where can I solder the sensor to the tank? maybe drill a hole for a stick. Maybe complete project already done ?
Regards.

No, you don't. That's only if your gas add-on system is excessively cheap. Properly designed systems have gauges visible from the driver's seat.
And seriously: if you have to ask those kinds of questions, then for both your own and everybody else's safety you have to stop thinking about that plan immediately. If you proceed then likely as not you'll create a lethal danger to everybody within blast radius of that gas tank.
Don't drill the tank, place an electronic pressure meter on the pipe leaving the tank.
Pressure meter will give you a current or voltage proporcional to pressure.
If changes in temperature are too big then a temperature meter will also help.
Calculate mass in tank using the standard mass pressure temperature gas equation.
