WirelessHart technology from Emerson allows high-precision tank gauging with installation costs 70 percent below those of wired systems. According to Emerson, companies can now benefit from improved inventory and loss control, and better utilization of tank capacity, on remote tank farms that have previously relied on manual data collection because wired instruments are too costly. Rosemount TankRadar Rex and Pro radar-based tank gauging system get their wireless functionality from Emerson’s Smart Wireless Thum adapter, which can also be fitted to other Hart field instruments. The adapter communicates wirelessly with Emerson’s TankMaster inventory software or distributed control system. The self-organizing wireless mesh network provides 99.9 percent data reliability even in an environment such as a tank farm, where large pieces of steel can obstruct radio signals. Every Thum Adapter serves as a network connector and backup, so there is no single point of failure. All data is secured by 128-bit encryption.
