VFD constant pressure water supply
Constant pressure water supply for a tall building, using a pressure sensor detecting the pressure in pipes, reduce the pump speed when the pressure reach to the upper limitation; And increase pump speed when pressure fall down to minimum limitation, therefore, to achieve constant pressure in the pipes.
What I want to know is the constant pressure water supply plc and inverter wiring diagram? As well as the operation parameters setting, control procedures?
