The OPTIMASS 1400 is a twin straight-tube Coriolis mass flow sensor positioned as a cost-effective, general-purpose meter. It measures mass flow, density and temperature directly and calculates volume, referred density, concentration and velocity. Paired with the MFC 400 converter, it adds comprehensive diagnostics and Entrained Gas Management (EGM).
