hello all,
iam working on a project where i have to indicate the level of sand present in the tank.there will be only 2 indications..Full and empty.a bulb or LED will indicate the position of sand.
**broken link removed**
now the issues are.
1.if u look at the picture the empty and full levels formed by the sand will be concave and convex.so floating and magnetic sensors won't work.
2.the inside environment will be very dusty so i can't use opto method.
can u guys help with this issue?
my friend said ultra sonic stuff will work.but can i use them for such condition?
