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 ...

AutomationDirect has added the Flowline EchoTouch, EchoSpan, and EchoSwitch lines of ultrasonic liquid level sensors and transmitters, as well as the PodView digital level indicator to their product ...

Levels change slowly in tanks that are usually geographically dispersed, making them ideal candidates for wireless sensor networks with minimal impact on control performance. Digital and wireless ...
