The AV Module is shipped with default storage rates of 15 minutes for the level velocity and flow rate and 1 hour for total flow and input voltage readings You can modify the data storage rates to log readings at a faster or slower rate Keep in mind that although the AV Module can store data as fast as 1 reading every 15 seconds faster storage rates will shorten battery life increase memory usage and lengthen Retrieve Data interrogation times You can also create conditional data storage rates The AV Module can log data at a secondary rate when user defined condi tions have been met For example an AV Module can store level readings at a primary rate of 15 minutes and a secondary rate of 1 minute when the level reading is greater than or equal to 1 foot Secondary rates allow you to collect detailed data when defined events of interest occur while reducing power and memory consumption when detailed readings are not needed To modify the Data Storage Rates first click on the Set Up Data Storage button on a measurement tab Then enter the Primary and Secondary Rate settings on the Data Storage Setup window Repeat this for each measurement type 3 7 2150 Area Velocity Flow Module Section 3 Programming 3 3 8 Site Name The modules are shipped with default names so that they can immediately begin to communicate with Flowlink You can change the site name to a more descriptive name on the Site Info tab in Flowlink Keep in m
