Density Sensors For Small Sample Volume: L-Dens 313/ 323

The L-Dens 313/323 density sensor is a powerful and flexible measuring instrument for the continuous determination of liquid density and concentration - from the milliliter to the hectoliter scale. The wide range of application programs makes the instrument extremely versatile.

The L-Dens 313/323 density sensor can be quickly and easily built into measuring systems and plants. Installation and cleaning are simple: The L-Dens 313/323 is connected to the production line via a standard flange (G 1/8“). The density sensor consists of one smooth tube. This design simplifies the cleaning process. All wetted parts are made of stainless steel (L-Dens 313) or hastelloy (L-Dens 323).

Anton Paar has been producing digital density meters working to the oscillating U-tube principle since the 1960s. The L-Dens 313/323 density sensor measures the density of the liquid according to this reliable U-tube method. The resonance frequency of the U-shaped measuring tube and the measured temperature are analyzed by the processor card. The result: automatic calculation of the density, temperature-compensated density or liquid concentration.
