DIMF 2.0 Density Sensor

DIMF 2.0 Density / Concentration Sensor

The DIMF series density/concentration meter is based on the oscillating element principle. The fluid to be measured flows through the oscillating tube that is excited electromagnetically and will oscillate at its natural frequency.

Changes in the density of the fluid lead to changes in the natural frequency. These frequency changes are picked up by the electronic transducer and converted into a signal proportional to density or concentration. The measured variable is available as a 4-20 mA output signal and can be shown on the integral display. Major applications are process control and quality monitoring of fluids in all areas of industry.

The device can also be used for density mass flow conversion suitable for custody transfer in connection with the corresponding volumetric meters and flow computers.
