Weighing Bucket Rain Gauge Instrument Handbook
- Brookhaven National Laboratory (BNL), Upton, NY (United States)
The OTT precipitation gauge is used for automatic determination of the intensity and amount of precipitation. In contrast to conventional precipitation gauges, the Pluvio2 works using the balance principle. The gauge reliably recognizes precipitation by determining the weight of the collecting bucket. A high-precision stainless steel load cell, hermetically sealed against environmental influences, is used as the sensor element. An integrated temperature sensor compensates for the temperature changes in the weighing mechanism. These sensors have been found to be stable for years. The orifice of the gauge is heated and when snow/ice precipitation occurs, the weight of its water equivalent is the amount observed.
