Hello,

Today I've got a possibilty to download the presentation "Technology Comparison: Snow Depth Detection"
from Luft, Meteorology Division of OTT HydroMet.

URL is https://www.lufft.com/snow-depth-measure...hitepaper/
you can download it after complete the questionnaire.

Manual is only "Insight for Experts", I do not distort the copyright, I only publish their conclusions:

   
It is clear from this that the method of measurement chosen and developed by engolling is the correct one.  Heart
Best Regards
Zdenek

Tuesday the snow height measurement registered the first bit of snow for this season  Smile .

See the temperature, the total counts of the tipping bucket and the snow height in the diagramm.
Everything still seems to work properly.
