Rain Gauges
Precision precipitation measurement
A tipping bucket is beautifully simple: rain funnels onto a tiny see-saw that tips at a known volume, and each tip is one count. These are the gauges — tipping-bucket and all-weather weighing — plus the screens and calibration tools behind ALERT and IFLOWS networks nationwide.
Tipping-Bucket Rain Gauge
The standard ALERT sensor: tipping-bucket assembly with 25 ft cable, mounted under the funnel-and-screen top section of a station standpipe. Backed by a lifetime warranty.
- 1 mm per tip resolution
- Included in rain and weather stations
All-Weather Precipitation Gauge
Not a tipping bucket at all: a load cell continuously weighs the collected catch, so rain, snow, sleet and hail all register — an antifreeze charge melts frozen precipitation as it lands.
- 0.01 in resolution; 12, 20 or 30 in capacities
- Operates −30 to +50 °C on 12 Vdc
Precision Tipping-Bucket Gauge
A precision tipping bucket with 8 in or 12 in orifice for reference-grade rainfall measurement; the 2500E adds a 120 Vac electric heater to melt snow and ice at cold-season sites.
- ±2% accuracy at 0–6 in/hr
- 0.01 in, 0.1 mm or 0.2 mm per tip
National Weather Service Rain Gauge
Built to the NWS tipping-bucket design for networks that must match Weather Service observation standards.
- ±3% accuracy
- 0.01 in or 1 mm per tip
Rain Gauge Wind Screen
Wind blowing across a gauge orifice deflects rain and under-reads catch. A Lexan wind screen restores accuracy at exposed and snowy sites; the mounting kit fits station standpipes.
Precipitation Gauge Calibrator
Drips a known volume at a controlled rate so field crews can verify gauge accuracy during routine maintenance.
