The emergence of smart meters, which greatly expanded the scope of application of traditional instruments, in recent years, intelligent measurement and control instrumentation developing rapidly. Domestic market has seen a variety of intelligent measurement and control instruments, for example, can automatically compensate for differential pressure orifice flow meter smart, intelligent temperature control procedures can be performed multi-zone temperature control device, and a variety of digital PID can be achieved complex control law smart regulator, and the ability of various spectral analysis and data processing intelligent chromatograph. With its small size, intelligent instruments, strong function, low power consumption advantages, rapidly in household appliances, research institutes and industrial enterprises have been widely used. In this thesis, microcontroller-based intelligent flow measurement and control instruments used in industrial production site, and its purpose is: Select the pipeline fluid flow setpoint temperature calibration procedure by eliminating internal fluid flow in the pipeline resulting temperature rise caused by traffic value and set value bias. The apparatus includes meter, the
