Density Computer FML621

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

FML621

Compare

Field of application

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.

Density computer for density, reference density, concentration of liquids.

Ambient temperature: -20 to +50°C (-4 to +122°F)
International explosion protection certificates

Benefits

Measurement used in tanks and pipes without the need for additional pipework
Large number of process connections to choose from: universal usage
Integration of existing temperature measurements for temperature compensation
No mechanically moving parts: no maintenance, no wear, long operating life
pump dry-run protector can be provided with the same process connection
Additional calculations, such as the mass of the product, can be performed in the Density Computer FML621
The integrated data logger supports users during operation and servicing
