Aeration Air Flow On PROFIBUS Communications-Based DCS In Wastewater Treatment Plant

A major municipal wastewater treatment plant in Scandinavia was incrementally upgrading and converting the plant’s control system from a traditional analog-based system (e.g. 4-20 mA) to PROFIBUS-based digital bus communications. The plant was very successful using, and has installed, FCI constant power technology thermal flow meters, Models AF88 and ST98, in the aeration lines for many years. Can FCI help them convert and upgrade the aeration flow control to PROFIBUS utilizing the same constant power technology thermal flow meters?
