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.

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 ...

Levels change slowly in tanks that are usually geographically dispersed, making them ideal candidates for wireless sensor ...

A small municipal water utility experienced frequent pump shut-off, requiring callout of a maintenance technician to reset the pump. Upon reset, no problems were observed, ...
