1, according to the design or actual requirements set flow, can automatically eliminate the pressure fluctuation of the system, keep the flow unchanged;
2, to overcome the system heat and cold uneven phenomenon, improve the heating (cooling) quality;
3, completely solve the near-end pressure difference, the distal pressure difference is small contradiction;
4, reduce the system circulating water, decrease the system resistance;
5, reduce the design workload, do not need to the pipe network cumbersome hydraulic balance calculation;
6, reduce the difficulty of network adjustment, simplify the complex network work to simple flow distribution;
7, to avoid the multi-source pipe network heat source switching of the flow redistribution work; 8, the flow display values are randomly calibrated on the test bench, Flow (H/h).
