New Cosasco® ER Wireless Transmitter for Tank Corrosion Monitoring

Transmitter allows affordable upgrade of aging tank monitoring systems

Santa Fe Springs, Calif. (May 3, 2016) – The new Cosasco® ER 300 Series Wireless Transmitter allows easy, affordable upgrade of oil, fuel or chemical storage tank corrosion monitors to fully automated data collection systems.


Corrosion in oil, fuel and chemical storage tanks occurs both internally, from corrosive water gathering in the bottom of the tank, and externally, from water seeping under the tank floor. Typically located in tank farms near suburban or environmentally sensitive areas, leakage of a tank’s contents caused by corrosion could have a disastrous impact on local ecosystems. To ensure the effectiveness of anti-corrosion treatment systems, storage tanks require both internal and external corrosion monitoring. Older tank farms often have inadequate monitoring systems with no integrated data management, limiting data quality and access.

The ER 300 transmitter uses WirelessHART7 and ISA 100 Wireless communication to allow easy integration with existing protocols, with no cabling costs. When installed, the transmitter can collect data from multiple monitors across a tank farm to create a comprehensive monitoring system that ensures the integrity of storage tanks. Wireless communication removes the need to visit the site to record data, saving travel time and providing the most up-to-date corrosion data.
