Tipping Bucket Rain Gauge
The Avimar Tipping Bucket Rain Gauge meets the specifications of the World Meteorological Organization (WMO).
Â The design uses a proven tipping bucket mechanism for simple and effective rainfall measurement. The bucket geometry and material are specially selected for maximum water release, thereby reducing contamination and errors. Catchment area of 200 cm2 and measurement resolution of 0.1 mm meet the recommendations of the WMO. Leveling screws and bullseye level are built in for easy and precise adjustment in the field. Measured precipitation is discharged through a collection tube for verification of total rainfall. Model 52202 is heated for operation in cold temperatures. An unheated version, 52203, is available for use in moderate climates. To discourage birds from perching on the funnel rim, accessory bird wire assembly may be attached to the gauge.
For coastal salt air applications and other corrosive environments, the gauge is offered with a marine grade stainless steel housing.
No Moving Parts
The Model 50202 Precipitation Gauge accurately measures rain or snow precipitation without moving parts. Insulated housings and thermostatically controlled heaters permit operation at temperatures below freezing. Unlike conventional tipping-bucket and weighing gauges the 50202 has no moving parts, making the instrument ideal for use on moving platforms such as buoys and ships. Precipitation measurement is made with a capacitive transducer and electronic circuit that produces a voltage output. Total precipitation can be tracked by a datalogger or recorder.
The Pressure Port minimizes dynamic pressure errors due to wind.
Ambient wind of 20 meters per second blowing over a typical barometer inlet tube can cause pressure errors as high as 3 hPa. The Pressure Port minimizes these errors.
