Here is a tested Arduino project that uses 3 sensor probes as water level indicator with 3 leds and one LCD display + a simple controller that turns on a motor when the water has reached the desired ...

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.

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 ...

We are currently in the process of putting in a backyard pool. This is an in-ground gunite pool. I inquired about an auto-fill system from the pool builder but he talked me out of it. He explained ...
