The Series 900 RTU Pump Controller with full remote monitoring and control capabilities. The controller is designed to control one or more pumps to keep a local or remote storage tank full or to control the system pressure. The inputs to the controller can be level, pressure, or flow. The controller will provide START/STOP commands for the pump. If a VFD is used, the controller can provide an analog output signal for variable control. An operator interface terminal is used to read system parameters and insert new setpoint values.

A Remote Terminal Unit (RTU) provides the SCADA master station with remote monitoring and control capabilities by transmitting and receiving over commonly available communications media – 2-wire circuits, dedicated phone lines, DSL, radio, wireless, etc. Licensed radios in the VHF, UHF, and 900 MHz bands are utilized as well as non-licensed spread spectrum and Ethernet radios.
