I've just come across a no-name non-contact, high-precision 80 GHz mmWave radar sensor for liquid level detection with a 40m ...

Use an Arduino Mega to measure the level of a liquid by means of a 4-20mA submersible pressure transducer. By connecting a resistor in series with the transducer, the voltage across the resistor can ...

Sometimes we need a non-contact liquid level sensor. There are several ways to build that, but the easiest is to try an optical liquid level sensor. You may already have an idea in mind since you are ...

SST Sensing has partnered with Sparkfun to develop a simple to implement solution for single point liquid detection using infrared technology. The solution comprises an Optomax Digital liquid level ...

Included examples slf3x-minimal This is a minimal example, reading out the data from the sensor and printing it to the serial console. Use the Arduino IDE's "Serial Monitor" to see the values read ...

This paper designs a fiber optic liquid-level sensor is used to measure the level of oil tank, introduces design, development process of the sensor and use this sensor to do experiment to verify the ...

Research from all publishers Recent advances in liquid level measurement have focused on both novel sensor architectures and sophisticated data analysis techniques.

A novel liquid-level sensor was proposed and studied by using a specialty double-cladding fiber (DCF). The resonant wavelength shift of DCF linearly depends on the fraction change of DCF immersed into ...
