The OPTIMASS 7400 is a Coriolis mass flow sensor with a single straight measuring tube, offered in titanium, stainless steel, Hastelloy or tantalum for demanding and corrosive applications. The straight tube drains easily, is simple to clean, and resists installation and process effects while offering excellent zero stability. With the MFC 400 converter it provides diagnostics and Entrained Gas Management.
