AWI is the leading developer of aviation weather measurement systems and air traffic management solutions.
AWI rain gauges are designed for many years of accurate, trouble-free operation. The built-in level and pre-drilled feet on our tipping bucket rain gauges will help to simplify installation. Our patented all-metal designs (including aluminum, nickel-plated brass, and stainless steel) ensures your rain gauge will maintain accurate operation for years to come.
The 6011 Series Tipping Bucket Rain & Snow Gauges are standard, precision instruments for measuring rainfall volume and/or rate. Rain enters the gauges through a large funnel, the rim of which is protected by a metal ring to prevent distortion. Collected water passes through a debris-filtering screen and is funneled into one of the two tipping buckets inside the gauge. The bucket tips when a given amount of water has been collected; the amount of which is determined by gauge calibration. As the bucket tips, it causes a 0.1 second switch closure. The tip also brings a second bucket into position under the funnel, ready to fill and repeat the cycle. After the rain water is measured, it drains out through tubes in the base of the gauge. These drain holes are covered by screens to prevent insect entry.
Various models in the 6011 series offer data collection in either standard or metric units. For additional details please see the specifications listed on our product data sheet.
The 6021 series Electrically Heated Rain & Snow Gauges are available for areas where snow or freezing rain may occur. These gauges operate in the same manor as the 6011 series gauges, but they are equipped with 4 separate heaters to ensure continuous operation even in extreme temperatures. A NiChrome wire heater wraps around the collection funnel to melt the precipitation. A second NiChrome wire heater warms the internal components and the gauge base to prevent refreezing of the water inside the gauge. In addition, a cartridge heater is installed into each of the two drain tubes so that the measured precipitation passes out of the gauge freely without freezing on contact with the cold outside air. The funnel and the base heaters are controlled by thermostats whereas the drain tube heaters are designed for continuous duty.
The Model 6021 is certified by the Federal Aviation Administration (FAA) meeting all of the most current regulatory requirements.

The AWI Model 6030 Optical Rain Gauge is a superior tool for rain measurement. The Model 6030's scintillation technology is the best method for optical measurement of rain. Falling rain causes beam intensity variations in the infrared light as it passes through the beam. These irregularities, known as scintillations, have characteristic patterns, which are detected by the sensor and converted to rain rate.
The Model 6030 was designed with a tough, yet lightweight frame, which can withstand the rigors of the most severe weather. Lens heaters keep the optical path clear of due or condensation, and the unit enclosure is rated NEMA 4 (IP 66).
