China’s water industry automation status assessment 1. China’s water industry instrumentation measurement and control systems instrumentation measurement and control system for water industry, including sensitive components, records show that sensors, transmitters and actuators and a number of other units. Its development process is divided into five stages: the first generation is the pointer type; the second generation develops to the discrete type; the third generation is the integrated circuit chip-based digital instrument; the fourth generation is the microprocessor as the core The so-called “smart ” instrument; With a variety of advanced technology and sophisticated electronic components continue to emerge, the fifth generation of powerful instruments
