In order to improve precision, outdated measurement method, complicated structure and weak anti-jam ability in liquid level measurement, a set of liquid level system was designed with the core of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.
