APPLICATION EXAMPLES8Specifications are subject to change without notice. When ordering, use the latest data sheets available at M-System web site.Sluice GatesSluice Gate Automation and Remote MonitoringSluices are built at river confluences where tributaries flow into the main stream. To prevent flowback of water into feeder streams, sluices are closed when the water level of a river rises high. Though most sluices are unmanned except at such times, once a rapid water level rise is observed, the gates require immediate operation. The DL8 Series Web Data Loggers provide a systematic solution for monitoring and recording of river water levels, and for opening/closing water gates automatically if an abnormality is detected. Wide-Area Remote Monitoring of Manhole PumpsSewers are generally gravity powered, though pumps may be used when necessary; for instance, where pressurized force is needed to convey water through undulating land or over long distances. A manhole pump lifts up sewer water to a higher elevation and then discharges the water to another gravity sewer. Terrain conditions in some areas require many pumps, however, which need time-consuming routine maintenance work. The DL8 Series Web Data Loggers provide an unmanned monitoring and reporting system to cover a number of manholes installed in a wide area.Web Data Logger, Remote I/O• Wide-Area, Remote MonitoringDL8 Series Web Data Logger with web server function monitors sites and provides data logging and event alerts.
