Pluvio 2S

The OTT Pluvio 2S is a next generation development of the tried-and-tested OTT Pluvio 2, with state of the art compact design that captures up to 400 mm of precipitation on a collecting area of 200 cm².

The OTT Pluvio 2S is an all-weather precipitation gauge that uses superior weight-based technology to measure the amount and intensity of rain, snow and hail.

Parameters measured include:

• Cumulative precipitation
• Precipitation intensity
• Bucket content (real time)
• Bucket content (non-real time)

The OTT Pluvio 2S employs a high precision load cell and algorithms that compensate for wind, temperature and evaporation, ensuring the highest accuracy precipitation measurements over time.

Precipitation Wind Shield (PWS)

To improve instrument performance in windy conditions, OTT has released a Precipitation Wind Shield (PWS).  The PWS improves aerodynamics in the area immediately surrounding the Pluvio 2S intake and minimises the turbulence impact on the precipitation to be measured.  Mounting the wind shield on the vibrationless concrete platform detached from the mast of the precipitation gauge itself, provides additional protection from wind induced measurement errors.

Why choose the OTT Pluvio 2S?

• Compact and relatively light precipitation gauge, with a weather resistant collecting bucket for 400 mm of precipitation (200 cm² collecting area).

• Minimum space requirement – no problem to install on existing 50 cm x 50 cm concrete bases • any suitable vibration-free 2-inch pedestals can be used again.

• The intensity and cumulative data output fulfils the WMO directive No. 308.

• Highly-developed data capture and processing with signal analysis, filtration and noise reduction as well as algorithms that compensate for the influences of temperature and wind.

• Considerable measuring accuracy of ±1 mm, wide measuring range, and a high data accessibility of 99%.

• Output of high precipitation intensities of up to 3,000 mm/h without any time delay.

• Precise capture of the finest precipitation from as little as 0.03 mm of precipitation in an hour.

• Optionally available with adjustable ring heater – prevents the formation of ice or snow caps and keeps the orifice rim free • also deployable in solar operation in reduced voltage mode.

• Various output interfaces (SDI-12, RS-485, pulse/contact), configurable through USB by means of tablet PC or notebook.

• Low overall operation costs – lifelong calibrated ice-free, drift-free and virtually maintenance-free measuring device.
