Application of Servo Control Amplifying Technology in Current Meter Calibration System

In order to improve calibration system and discharge in China, renovation of current meter accuracy and automation level of instrument for flow velocity calibration system was carried out by applying servo control amplifying technology with mechanical technology and computer technology. The system after renovation can improve performance parameters of the current meter calibration vehice. The thesis makes an analysis on technical design for the new style vehicle by using servo control technology, and a summarization about system performance and index, also gives a contrastive analysis on application situation of comparative measurement of the new style vehicle. It shows that the vehicle can fully realize design idea, and is characterized by good accuracy and reliability.
