Measurement System for Liquid Level based on Laser Triangulation and Angular Tracking

This paper introduces a kind of measurement method of the displacement for the liquid level by the use of the laser triangulation and the angular displacement tracking. Based on the principle of the laser reflection and the principle of the source synchronous tracking, according to the triangulation method and the optoelectronic matrix imaging technology, it realize the corresponding relationship between the liquid displacement and the light imaging. Thus to obtain the actual data of the height of liquid level. This method can be used for a large number of-way, high-precision measurement of the liquid displacement of Newton, and to overcome the existing the difficulties and problems in the non-contact measurement for the height of by ultrasound.
