Abstract:

In order to verify the accuracy and reliability of the engine flow measurement and control equipment,in the paper,a set of the calibration system for flow measurement and control equipment is established,realize the calibration of the engine flow measurement and control equipment.The uncertainty analysis of the engine flow measurement and control equipment is completed,and the key hardware system of the calibration is built,the software system of the calibration is developed,so realize the automatic control and calibration of the engine flow measurement and control equipment,the calibration system has the characteristics of flexible configuration and simple operation.

Key words: Flow regulator, Uncertainty, Flow measurement and control equipment, Measurement and control system
