Title The Temperature of the Liquid Flow Measurement and Control System Design Based on C3000 Process Controller
Abstract
Industrial control needs to deal with problems of liquid level, temperature and flow control, however, with the development of industry, the systems become more complex to control the liquid level, at the same time, requires further ascension. In order to cope with the requirements, people begin to speed up the development of industrial automation, The automation equipment is the most representative, such as distributed control system (DCS), it is widely used because it has a variety of excellent properties. Compared with the traditional analog electric instrument, it is convenient. The soft connection mode is easy to change, flexible to display, large data storage capacity and so on. For flow surface temperature measurement and control, it has convenient operation and management oversight, control function, risk dispersion and high reliability and so on. Through the learning and use of ZHE JIANG university central C3000 process controller on the CS4000 system temperature, liquid level and flow rate of circuit testing and control, and through the analysis of the control data change parameters to the results of experiment.
