VFD Control System with Remote Radio Control

This customer was faced with an interesting challenge at an environmental cleanup site.  A pump was needed to pull water at a variable rate from a deep well in a very remote location.  Due to the unique circumstances of this project, modern remote communication technologies were not an option.  Our team was able to help our customer engineer a solution that uses a data radio modem to control the variable frequency drive (VFD) and submersible pump.  After acquiring the required FCC license to operate the transmitter, this system can now be controlled from a base station far from the well.  The project has gone so well so far that additional systems are now in planning for future installation.
