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 ...

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 ...

Will not be affected by the type of liquid. Can detect the liquid level of boiling water Strong compatibility penetrates all kinds of non-metallic containers or pipes such as plastic, glass, ceramic, ...

Abstract: The present study designed the dual-point liquid level measuring sensor using the polymer optical fiber (POF). The sensor measures the liquid level variation based on the optical power ...

Abstract: This article proposes an intensity-modulated liquid level sensor (LLS) based on cascaded long-period fiber grating (CLBG) and fiber Bragg grating (FBG) structure with temperature ...
