Hydrostatic pressure produced by the water column at the bottom of the controlled liquid reservoir uses the trapped air in the measurement tube to produce the same amount of pressure on the sensor. At ...

This reference design describes a cost-effective, low-power liquid-level measurement data acquisition system (DAS) that use a compensated silicon pressure sensor and a high-precision delta-sigma ADC.

This project circuit helps to detect and control the water level in an overhead tank or container. Here, we use 8051 microcontroller. This is an interesting and very useful project in our real life.
