LBA Flux Towers
LBA Flux Towers - Data Collection System
LBA Flux Towers before telecommunications system • Sensors data recovery only during weekly site visits
NO
• No remote alarm or any indication of equipment failures
LBA Flux Towers before telecommunications system
• Logistic problems: • Loss of time and money with failures maintenance trips to the sites • Loss of data !!!
