S2N - Wastewater Pump Shaft Monitoring System

The system transmits measurement data via wireless LoRaWAN or NBIoT technology to a cloud server and from there to the user via the Internet. By processing and analyzing large amounts of data collected in real time, maintenance processes can be optimized and a much more efficient use of resources can be achieved. It is also possible to coordinate the operation of pump shafts operating over great distances. Due to continuous monitoring, operating and maintenance costs can be reduced and power consumption can be optimized. Traditional preventative maintenance is replaced by proactive predictive maintenance. The useful life of the equipment greatly increases, anomaly detection becomes more accurate, major failures and costly shutdown cases are prevented. The probability of failure can be predicted with high accuracy, and even installation costs are reduced.

If the threshold values, defined jointly with the user, are reached / exceeded, the system sends a warning signal / alarm, but it is also possible to set a warning based on trend analysis; e.g. the alarm can be triggered in the event of an increase in current consumption or operating time, or a decrease in the amount of water supplied, not merely when the limit values are reached and a crisis occurs. Another option is the use of data from different pump shafts, operating in the area, or even include meteorological data to assess proper operation. The individual elements of the complete monitoring system can be coordinated, and the system is able to send warning and alarm signals even on the basis of relative values.

The data is displayed in a tailored way fitted to the needs of the customer, even on a mobile device. Access to the data is performed in a secure, password protected manner, according to the user`s needs.

The system automatically generates daily / weekly / monthly reports on the measurement data, which can be exported in xls or csv format as per user’s requirements.

The S2N Wastewater Pump Shaft Monitoring System can successfully be applied to both new and existing pump shafts networks.
