Compact, reliable and precise.
The only compact professional 200 cm² ultra-low-power Class-A rain gauge capable of high-precision rain measurement without regular maintenance. It is designed for mass sensor deployments in smart cities and smart agriculture. Its high accuracy and repeatability of measurement make it suitable for replacing aging WMO and NWS compliant meteorological equipment.
New self-balancing magnetic tipping bucket reduces and resists the effects of dirt, vibration and installation leveling errors. It is more accurate than many “professional rain gauges” with its self-balancing magnetic tipping bucket mechanism.
Durable impact-resistant and UV sunlight resistant materials with over 10 year life
Excellent Class-A rain intensity gauge with accuracy of rain measurement per UNI EN 17277 Hydrometry Measurement requirements
Long-term maintenance-free operation due to the simplicity of design
Dirt & dust resistant magnetic self-balancing measurement principle
For hydrology, urban-meteorology, agriculture, smart-city, resilient city, and research.
STABLE MAGNETIC PRECISION
Single drop precision with the magnetic self-balancing
Self-emptying magnetic tipping bucket
Consistency of measurement with +/- 1 drop tipping resolution
Very resistant to wind induced vibrations
Highly resistant to measurement drift from contamination and condensation
Magnetically stabilized self-emptying bucket is adjustable with only a screwdriver
Easy to maintain
Low sensitivity to non-level mounting.
Simple design with electrical parts hidden from reach for reliability, easy field calibration, and maintenance.
Class-A precision even in torrential downpours
Consistent and accurate magnetically-balanced mechanism in less affected by residual water and condensation than any other butterfly style tipping bucket mechanism. This inherent property makes MeteoRain® the most consistent self-emptying rain gauge on the market.
Maintains high Class-A measuring accuracy up to rain rates of 10 mm/min (0.4”/min) mm/hr), 600 mm/min (24”/hr) or 50 tips per minute.
Highly resistant to wind-induced vibrations compared to standard tipping bucket rain gauges.
Highly resistant to drift and measurement error from dirt accumulation.
Magnetically stabilized for easy adjustment and consistent measurement in all non-freezing temperatures.
Tipping bucket design is protected. (Registration pending)
MAINTENANCE ADVANTAGE
Self-cleaning material & dirt resistance
UV sunlight resistant material for long operational life in direct sunlight for 10+ years.
Good hydrophobic properties offer a self cleaning effect and good drainage for accuracy.
Field serviceable and easy to clean with a cloth.
Replaceable sieve is easy to clean.
Designed for a 10+ years life in all climates.
Electronics are coated with a weather-resistant coating for all-weather durability including winter, snow, ice, and salt spray near the coast.
CALIBRATION & RAIN RESOLUTION OPTIONS
Available in ±1 % accuracy. For general use, standard factory calibration and resolution of 0.2 mm (0.2 liters per square meter) per tip offers ±2 % accuracy. Custom resolutions and accuracies for this udometer, pluviometer, or ombrometer rain gauge are available upon request.
0.10 mm/tip (0.004"/tip) Special order
0.20 mm/tip (0.008"/tip) Factory default (World standard)
0.25 mm/tip (0.01"/tip) Special order (USA standard)
±1 % accuracy available as special order
MOUNTING & PROTECTION
Universal pole & wall mount included
Makes mounting quick and easy with the use of screws, u-bolts or widely available hose clamps. Fits pipes from Ø 1.5" (Ø 35 mm) diameter and larger. Mounting screws are included. U-bolt or hose clamps must be purchased separately.
Bird spikes (Optional)
Bird protection spikes prevent birds from pooping into the rain bucket or nesting in the rain gauge funnel. Overall effect is improved long-term accuracy due to cleanliness and reduced maintenance with longer service intervals.
Leaf fence (Optional)
Leaf/debris fence prevent prevents large debris like leaves from collecting in the rain bucket of the rain gauge. Leafs can trap, absorb and prevent some water drops from reaching the measuring mechanism.
Although we offer an optional leaf fence, we do not recommend a leaf fence for the MeteoRain® 200 Compact rain gauge since its funnel design allows the wind to remove most larger debris from the funnel naturally. Due to the accuracy of the MeteoRain® measuring mechanism, a wire mesh leaf fence tends to trap water drops on it, thus negating much of its benefit.
