Historically, retractable ER probes are inserted into the lower part of the tank wall to provide monitoring internally and, for external monitoring, Cosasco's underground 620HD ER probes are installed under tank bottoms. These were read with a handheld device.The new ER 300 Series Wireless Transmitter makes upgrading to a fully automated data collection system more affordable, without the costs of cabling. With WirelessHART7 and ISA100 Wireless communication options, ER Wireless Transmitters can be easily integrated with existing process monitoring systems. The ER Wireless Transmitter connects to a 620HD and 3500 probes via a probe adapter. Metal loss measurements are transmitted back to a Gateway and onto a server with Cosasco Data Online software.
