The second wettest monsoon in history proved the durability of our loggers and battery cases this past summer. Nearly 40 City of Tucson facilities, ranging from fire and police stations to parks, aquatic centers and a zoo, were audited for water efficiency. Frequent heavy downpours flooded meter boxes with water, sand and muck. Because MagneFlow loggers are sealed and potted, and our battery cases meet the IP68 standard, no loggers were lost. No data was lost, either.
