Remote Monitoring and Process Control in Drinking Water Distribution Networks

When it comes to effective management of water distribution networks, flow velocity in distributed water is a very important factor. Precise knowledge of stored and consumed water quantities can only be achieved through a flow measurement system that performs bidirectional measurement. Electromagnetic flowmeters can perform high-accuracy regional measurements, providing all the information necessary for precise monitoring of the system's water inlets and outlets. The measurement points in these systems are generally located in areas that are difficult to access, such as manholes. Furthermore, even if energy connection is available at these measurement points, their location is quite distant from control centers. To collect and process measurement data centrally, values must be partially gathered from these remote points. This is precisely where Krohne provides a specialized solution by integrating high-accuracy flow measurement with GPRS communication for remote monitoring and management of drinking water networks. In this solution, wireless transmission of analog or digital outputs such as flow, conductivity, pressure and temperature is enabled through a mobile network-based control station. In this system, an ODP protocol is used for secure data transmission (transmission with time stamp) and the protocol's integration into the monitoring or visualization system can be performed via OPC DA. Additionally, to enhance IT security, a firewall can be established using a special APN and hardware.     Can Merter Marketing and Communications Manager Krohne Otomasyon San. ve Tic. Ltd. Şti.
