Guys, I run my car on Waste Vegetable oil and will soon be putting a 2nd tank (old glass lined water heater) under my car.
I intend to use a picaxe to monitor temperature at various critical points (probably using DS18B20). I would like to build a Oil level gauge to give me some indicative levels for the vegoil tank - level of say 10%, 33%, 66% - Full would be close enough.
Anyone got an idea of a good way to do this - that would be OK immersed in Vegoil on an ongoing basis. ?
I will be using an old electric hot water tank so by removing the elemnt will have an approximately 2 inch opening to insert the unit through.
In intend to use a 2 or 4 line LCD for display in the car. I am OK on the programming side, just weak on the actual electronics.
Thanks in advance
