The L-Dens 427 series of density sensors provides an accuracy of 1 x 10-4 g/cm³ in a compact design. Continuous measurement of density, concentration and API gravity optimizes production processes and ensures a consistently high quality of product. Their small size allows the sensors to be easily integrated into other measuring stations, e.g. for determining the mass flow rate. They measure all low-viscosity and non-corrosive liquids.
