Liquid Level Measurement

A low-cost intensity-based polymer optical fiber (POF) sensor for liquid detection applied to volumetric flasks is presented. Experimental results demonstrate the viability of the POF-based sensor system in a high-accuracy liquid level measurement scenario. Moreover, a wireless mesh sensor network based on ZigBee specification protocol to address multiplexed POF-based sensor is also developed. Experimental results demonstrate the feasibility to address a high number of optical sensors in an industrial process framework by means of this low-cost wireless solution.

Measurement Experiment

In order to improve precision, outdated measurement method, complicated structure and weak anti-jam ability in liquid level measurement, a set of liquid level system was designed with the core of high-precision laser displacement sensor. The system adopted non-contact laser trigonometric survey method and powerful virtual instrument techniques. It could conduct online and real-time measurement to infinitesimal displacement on liquid level with high speed and precision. Through measurement experiment, its accuracy and practical applicability is verified.
