I need a sensor for measuring level of liquid in a tank. The method of measuring should be non contact type. Please give any suggestion. I want to interface the sensor with a microcontroller like STM32 or AVR.
Tank diameter is 2m and depth is 5m. The liquid inside is industrial coolant. Use will be indoors. Continuous measurements is needed and three switches are required to be activated depending upon the level.
I am interested in the following sensor. MB1000 LV-MaxSonar-EZ0 or MB1010 LV-MaxSonar-EZ1. Please suggest.
