Abstract

The design and development of a digital liquid level sensor system based on parallel fiber sensor heads are presented. A novel parallel fiber sensor heads based on side-polished common single-mode optical fiber is designed and applied. When the sensor head contacts with the liquid, we observe a sharp decrease in the output intensity. The digital liquid level sensor system based on 16 sensor points is operated by using an optical source with limited power. The measurement resolution and range of the liquid level sensor can be selected by adjusting the distance between the sensor heads. The advantages of this sensor system include low cost, high sensitivity, simple structure, excellent real-time character, high stability, and temperature-insensitiveness in normal temperature and pressure.
