DENSIMETRY SENSOR DP-10
Density measurement of liquid de-icing agents NaCl, CaCl and MgCl in water during brine production
Liquid de-icing agents are considered to be the ideal solution to cope with icy roads since a long time. The density meter DP-10
was especially developed for the requirements of winter road services when it comes to mixing the brine. Further fields of application are brine stations and salt mixing stations.
Other than the conventional, manual density measurement using a spindle, it‘s the DP-10‘s advantage that – via a bypass – the
measurement can be done in process condition and therefore in real-time.
Choose the suitable measuring device according to your individual needs: The standard version with analogue output for
further data processing, an enhanced version with internal LEDdisplay (DP-10/A) or the system solution with integrated mixing controller and LED-display (DP-10/MR).
- Real-time measurement
- Device facilitates automated mixing processes
- Different, suitable system for all requirements
- Robust construction for applications in demanding environmental conditions
- Easy installation and operation
- Winter Road Services: Designed for accurate brine mixing (NaCl, CaCl, MgCl) to manage icy road conditions.
- Brine & Salt Mixing Stations: Used in stationary mixing stations for continuous quality control of de-icing agent concentration.
- Automated Mixing Processes: Ideal for automation, providing real-time bypass measurements for precise, continuous mixing—far more accurate than manual spindle methods.
