The OPTIMASS 2400 is a large-diameter Coriolis mass flow sensor developed for bulk measurement and custody transfer of liquids and gases, particularly in oil and gas. Multiple large straight measuring tubes give high flow capacity with an optimized flow divider for low pressure loss. With the MFC 400 converter it measures mass, density and temperature and calculates volume and concentration, and it suits petroleum and crude oil as well as products like syrup, molasses and raw chemicals.
