Universal precipitation gauge using the balance principle for liquid, solid, and mixed precipitation
It does not matter whether it is drizzle, sleet, hail or snow, the new OTT Pluvio² reliably and accurately measures both, the amount and the intensity of liquid, solid, and mixed precipitation.
It works according to the balance principle, taking account of external factors such as temperature and wind that could distort the results. Both, digital outputs (impulse/0.1 mm and frequency/status) and the serial interface, freely configurable as SDI-12 or RS-485, are available for transferring the data.
High-precision technology and robust design provide high accuracy and complete reliability.
Load cell and sensor electronics are hermetically sealed against damaging environmental influences. We have designed the carrier, bucket and protective housing parts to be particularly robust and we have ensured the use of high-quality materials.
Advantages
Accurate and reliable data in all weather conditions
Fulfills all requirements of WMO-manual 306, No. 8 (WMO = World Meteorological Organisation)
Measured data can be directly compared to the data measured by the classic Hellmann-rain gauge (bucket without a funnel)
Measurement accuracy of 0.1 mm - for the whole life of the unit
Conceived for a precipitation intensity range of 0.1 to 30 mm/min (1800 mm/h) the OTT Pluvio² reliably measures the drizzle of the temperate zones as well as heavy tropical rains
Bucket orifice without a funnel - heavy and solid precipitation are also recorded with precise timing
Ring heating optionally available- no formation of snow caps
Anti-freeze prevents freezing- operation without compromise even in areas with high levels of snow and frost
Possiblity of solar power supply- for deployment at self-sufficient measuring stations
Non-sensitive and robust
Maintenance work is limited to emptying the collecting bucket, occasional visual checks, and adding anti-freeze as necessary
System-compatible - measured data, alarm-and error messages are available via standard output interfaces
Examples of use
Meteorological stations, climatologic research projects
Municipal hydrology, landfill sites
Flood warning networks
ASOS - airports
Agriculture and forestry, irrigation plants, renaturation projects
