Abstract: With the development of modern computer technology, flow totalizer control system develops correspondingly quickly. Aiming at being small and intelligent, we use advanced MCU as main controller of the system, which has the ability to download programs. To provide workers a friendly interface, we design a controlling board with LEDs and a mini-keyboard; cording to requirement, printing and data storing and switch output are also designed; we choose AC-DC power module as the system power. So all above compose of a high precise platform.
