Optiqua EventLab

Optiqua EventLab is a solution for real-time monitoring of water quality in networked applications such as drinking water distribution networks. EventLab is designed for deployment as a high density sensor network, with distributed sensor nodes connected to a central server for data collection and processing. EventLab provides a generic approach to monitoring quality and event detection by measurement of the refractive index and changes therein. A network of EventLab systems allows online detection, localisation and (back) tracing of water quality issues, providing the real-time information required for a timely and effective response. Furthermore, stand-alone EventLab sensors can also be used at treatment plants, for intake protection and in bulk water supply exit / entry point control applications.

Optiqua EventLab is optimised for deployment as a network of sensors to monitor the drinking water distribution network. The major components of the EventLab early warning system are an optical refractive index sensor, data transmission infrastructure and software for data analysis and event detection. The sensors are easy to install, requiring minimal on-site infrastructure, and low in maintenance. Measurement data is transmitted from the monitoring stations to a central data server through cellular networks (2G, 3G), or alternatively can be transferred through SCADA. The ease of use in combination with wireless data communication allow for a distribution network wide Early Warning System.

Data analysis and event detection is performed by algorithms in a central data collection and analysis software: EventLab Online. EventLab Online uses advanced software algorithms to analyse the baseline data and automatically pick-up and flag abnormalities. The data and the analysis results are available to the user through a web based user interface as well as an XML based application programming interface for machine to machine communication.
