09.04 What are the benefits of VFD controllers?

Variable Frequency Drive (VFD) controllers allow for variable flow output to accommodate a range of operating conditions. The controller is set to operate with a pressure transducer input to maintain a constant pressure in the fuel supply pipe. With multiple generators, the controller automatically adjusts to the increased flow requirement when more than one day tank needs fuel.

A secondary benefit of the VFD controller is for soft start and stop of the pump to minimize fluid hammer issues in longer piping runs.
