Benefits include reductions in chemical costs, environmental impact and corrosion rates. Key features of the BGMobile App include: -INSTANT ACCESS TO YOUR SYSTEM’S STATUS- Upon connecting, the user will instantly see the status of the BG4 controller to be assured the water system is clean (green status) or warned by a triggered IAPP or IGEN alarm (red status) that biofilm activity is on the rise and a chemical biocide treatment may be warranted. -DOWNLOAD AND GRAPH DATA LOGS- Further analysis can be done by downloading data logs from the BG4 controller and viewing data graphs directly on the BGMobile App. The data trends in the graphs will help the user understand when biofilm activity begins to increase or decrease, thereby enabling users to optimize the chemical biocide treatment program of water systems impacted by biofilm growth. -SHARE DATA LOGS- Data is shareable to whomever the user chooses. Use the BGMobile App to easily attach data logs as a .txt file to an email or send through any other App that can store or send .txt files.
