The circuit was intended for monitoring and measuring the fluid level or content in a storage tank or reservoir by providing visual display with an audible alarm that can be switched. Light Emitting ...

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.
