How about a capacitive sensor? It can be built using a pipe and 2 long pieces of metal (Al). Those pieces make the 2 electrod's of the capacitor. Use a audio generator or so and a circuit for measuring the atenuation of the signal.Langat said:Hello there,
I would like to do a project on liquid level detection. It should be a able to detect instanteneous levels (e.g in a fuel tank) and indicate on a digital display. I would greatly appriciate suggestions on the same and probably the components I can use.
