Liquid-level sensing based on capacitive sensors comes with its own challenges. It’s like absolute capacitance sensing. Unlike touch detection, the absolute value of the liquid level needs to be ...

Liquid-level sensing is used in consumer electronics appliances like washing machines to detect the detergent level. The sensor technolo­gy has progressed to such an extent that refrigerators can now ...

Abstract: This paper presents the development of a capacitive level sensor for robotics applications, which is designed for measurements of liquid levels during a pouring process. The proposed sensor ...

A sensor that can detect the water in a beaker, container or tank from outside based on capacitance measurement. Detection of Water overflow in a tank is one of the main topics when it comes to energy ...

Abstract: Liquid level measurement is important requirement for building and industrial applications. One of the most popular methods for level measurement is the capacitive sensor. Most of the ...

Liquid level sensor, also called fluid sensor or float switch, usually has two parts: a stem and a float. The stem is stationary and attaches to the top or bottom of a tank. One or more reed switches ...

Alternatively to the ultrasound-based sensor, it would be more elegant to use capacitive displacement sensor. It works by detecting changes in dielectric constant near the sensor plates.
