Research on High-precision Real-time Online Measurement of Liquid Level Changes

The problem of low precision exists in current measurement techniques. This paper introduces the structure and working principle of the liquid level measurement system of laser triangulation and carries out a high-precision real-time on-line measurement of the water surface height variation by using the liquid level measuring system. This paper introduces the structure of the laser triangulation displacement measurement system and its working principle, testing its characteristics and anglicizing the reason of error.
