In these applications telemetry systems were implemented to control remote pumping stations and to view their status from a central control centre.
Gas is brought in from fields in the North Sea and stored before being pumped throughout The Netherlands to local storage systems and users. Before the application was implemented local service engineers were called out to visit the unmanned pumping stations if a problem occurred.
By implementing a telephone modem connection to the pumping station control system the status could be read and analysed before sending a service engineer to investigate. Data from the pump station could also be collected centrally for analysis and presentation. In this application Allen-Bradley PLC’s and SCADA software were used.
