On behalf of the Acomass company, we made a control and supervision system for the sludge pumping station for a sewage treatment plant located in the West Pomeranian Voivodeship. The system is based on the MT-151 LED telemetry module, which serves as a control unit and transmits measurement data. The visualization application was made in the Movicon 11 environment. It allows you to view the current state of the sludge pumping station and biological reactors of the sewage treatment plant, review graphs of historical and current data and alarm messages. Historical data is stored in a relational database.
