            CSO 
              Monitor 
            
            The 
              ELAN Technologies CSO Monitor is designed to monitor and data log 
              the time and duration of CSO events. The CSO Monitor comes complete 
              with a data logger in a weather tight case, a precision float switch 
              or proximity switch and software.  
             
            In the field, the sensor is mounted to sense the overflow event. 
            For a weir wall type, a float switch is supplied and mounted with 
            the activation point in line with the overflow. For a tide gate 
            type, a proximity switch is supplied and mounted on the gate. The 
            supplied cable is then run to the monitor mounted at the manhole 
            or structure entrance. The sensor connection to the monitor is made 
            via watertight connector and the gasketed case provides excellent 
            protection in harsh CSO environments. 
             
            In 
                
            
            operation, the logger monitors date and time and logs when an event 
                occurs. Using the supplied software, the logger is downloaded on 
                a monthly basis in the field with a laptop PC or disconnected from 
                the sensor and brought in to a desktop PC to download.  
                 
                The logged information includes the date and time of when events 
            started and stopped as well as the exact duration of the event. 
            This data can then be printed in a report, which can be attached 
            to a Discharge Monitoring Report (DMR) or used to generate a DMR 
            for submission to the EPA. 
                
               
            The 
              logger lasts over one (1) year on a single battery and can accommodate 
              over a month of data at 5-minute intervals, making it ideal for 
              meeting CSO monitoring requirements.
