Figure 2. 2005 Installation at the SPDC Sandhill Pond Entrance <br />During 2005 operations, the CDI equipment provided a promising level of performance <br />with regard to performing on -site functions and in reliably performing data transmission <br />tasks. Performance of third -party level sensors on the other hand was somewhat <br />sporadic. The ultrasonic "down- looker" level sensors that were being used at both sites <br />repeatedly lost accuracy at temperatures approaching freezing. <br />Another system "snag" encountered during 2005 was related to attempting to collect data <br />at two office locations. The Project 3 software which is available for download from <br />CDI's web site was developed for systems with a single data - collection node. As field <br />sites were polled by an office base unit, Project 3 would reset the field units to write the <br />next data in the initial Modbus register of designated field registers for data logging. <br />Unless a second base attempting to retrieve the same data did so before the subsequent 15 <br />minute data cycle, or else some data registers would be overwritten. It was deemed <br />important for the CDWR or an entity acting on CDWR's behalf (i.e. LSPWCD) to <br />receive direct transmission of recharge project field data. At the same time, it was <br />important for SPCD to also have real -time access to the field data to ensure that all fields <br />sites are functioning properly at any point in time. <br />Overall, SPDC recognized significant value in benefits it could realize from electronic <br />flow monitoring coupled with a reliable wireless data telemetry system. The limited - <br />scope of the 2005 demonstration project left SPDC interested in seeking a means of <br />extending the demonstration to develop a framework for a network that could potentially <br />be beneficial for multiple water using entities in the area. <br />4 <br />
