i am building an ink level maintainer which checks and maintains a specified level of ink in ink bottle...what i need is an analog sensor which can tell the depth to which the ink bottle is filled....i hav thought of 2-3 types of sensors but am not sure they will work..please help me out.
1)ir distance sensor: but i dont think the ink surface would reflect enough ir ray as it is a fluid as well as black/dark blue in colour...
2)weight sensor: lets say i want 20ml of ink in my bottle..so i can calculate the weight for 20ml..now if there is lesser ink than 20ml ,the weight would be less ..i can measure this weight difference and convert to voltage...but i dont know how sensetive this system would be..and even if i can measure weight difference for small drop in ink leve,i dont know how to convert this weight into voltage...
3)ultrasonic sensor: but i dont know how to use it to find the ink level in a small bottle?i mean the bottles are very small and i dont think sound is agood option for it....
i dont really think any of the 3 options above will work...can anyone tell me a better soln. to my problem...in need of urgent help...pls reply asap...
