Paper Abstract

A liquid level sensor based on fiber optic array and magnetic coupling is proposed and demonstrated. Besides the inherent advantages of fiber optic sensor, this sensor has a feature of digital sensing signal since the accurate value of light intensity is not needed, so the instability of light source, connecting and bending losses of optical fiber don't affect the measurement results. Owing to its special structure and package, the sensor is insensitive to the fluctuation of liquid level and could be used for measuring the level of almost all liquids regardless of their corrosivity and transparency.
