Vibronic measurement
Density Computer FML621

Measurement of density, reference density, concentration of liquids in conjunction with a Liquiphant

  • Density Computer FML621 ©Endress+Hauser

The density measuring line can be used in all liquid media for medium detection, to calculate the reference density, to calculate the concentration of a liquid, to convert values to different units such as °Brix, °Baumé, °API etc. Additional software modules, such as determining the reference density, intelligent medium differentiation and concentration identification, support the user in monitoring the quality. EEx ia, EEx de and EEx d explosion protection for use in hazardous areas.
