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.
