OTT Pluvio 2 L at [[http://www.awipev.eu/|AWIPEV Ny-Ålesund]], Svalbard, next to the atmospheric observatory.

===== Measurement principle =====
The OTT Pluvio 2 L is a precipitation gauge basing on a weighing measurement principle. It detects both liquid and solid 
precipitation by weighing the bucket content. The following values are recorded:
  * intensity
  * accumulated intensity
  * bucket filling level
  * temperature load cell

The instrument is equipped with a orifice rim heater to prevent accumulation of snow and ice on the orifice rim.
