Abstract: The
five units of pumping station are monitored and controlled by
modern distributed system. The data is transmited through
two-wire system network between intelligent apparatus and
computer. Approximate 140 real-time parameters of operating
mode, common data and main calculated data such as pump
effiiciency of 5 units are collected and displayed
simultaneously on the spot. The computer can manipulate
operating pump mode according rate of flow, pressure,
electricity or pump effliciency, The pumps will work in high
efficiency range and operational profit will be improved when
the system is set up in auto control state.
Key words: Water
