Frequency converter (VF) for constant pressure control of water supply
system uses industry-leading SPWM (sinusoidal pulse with modulation)
technique and high performance space vector and provides V/F VVVF (variable
speed variable frequency) control. Using modern pressure sensing
technique, it collects information about pipeline pressure changes in real time and
adjusts the rotation speed of the pump accordingly. This makes the exhaust pressure
constant, thus saving water and electricity.
