Based on the principle of laster triangulation measurement,a high precision liquid level inspection system for multiple objects in a relatively harsh working environment was developed.The system used the liquid communicating vessel liquid level of high principle,separation of the detection system and the work area,obtaining liquid level signal by laser displacement sensor,through the computer software application LabVIEW technology analysis,can draw the liquid level changes.Sensors in the linear motor drive,can realize the real-time level on 12 object detection.Experiments show that the error of the system,designated detection rate is less that ±0.6%,12 repeated measurement error is less than ±0.05 mm,has a good effect in practical aplication.
