【Abstract】 This paper introduces a flow controller designed for monitoring the solution density of the water treated system. It uses SCM as the primary computer, and through the series control it realizes to control those objects having the nature of large time-delay in the sense of software designs,it uses the thought of modularization and adopts C language for the application program of SCM. The controller’s all characteristics now have met the requirements of users it has the powerful capability of adapting field.更多还原
