Pipeline Telemetry System

ProtoLink designed and fabricated three enclosures housing Koyo PLCs to detect flow rate discrepancies between each end of a pipeline located on the eastern shore of the Caspian Sea.  On both ends of the pipeline, the system polls an Omni6000 flow computer via Modbus to collect flow data.  Data was telemetered between these sites and a third location using Microwave Data Systems MDS 4310 radio transceivers and the DirectNET protocol.  The system presents data to the user in both Russian and English via a Triton Technologies display panel.

In delivering this solar-powered system, ProtoLink was responsible for all hardware, software, and integration, including all panels, drawings, and PLC code development.  To address similar functionality requirements at the three locations, ProtoLink developed self-configuring PLC code, thereby eliminating the need for individual control programs for each site and simplifying system maintenance.
