Density measurement of liquid de-icing agents
The density meter DP-10 developed by SOMMER Messtechnik helps to detect the concentration of NaCl, CaCl or MgCl in water when producing brine. As a measuring method oscillating transducers are employed. Brine stations and salt mixing stations are typical implementation examples for the DP-10.
Features and advantages
- 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
Density measurement made easy
Liquid de-icing agents are considered to be an 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. 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. Depending on the individual requirements, different product variations can be selected: The standard version with analogue output for further data processing, an enhanced version with internal LED-display (DP-10/A) as well as a system solution with integrated mixing controller and LED-display (DP-10/MR).
