RAIN GAUGES
MODEL 2501 — Tipping Bucket Rain Gauge
General Description
The Model 2501 Rain Gauge was designed for the National Weather Service to provide a reliable, low-cost tipping bucket rain sensor. Its simplicity of design assures trouble-free operation, yet provides accurate rainfall measurements. The tipping bucket mechanism activates a sealed reed switch that produces a contact closure for each 0.01 in. or 1 mm of rainfall. The gauge has an 8 in. orifice and is manufactured of aluminum. Enclosure surfaces are powder coated gloss white. The funnel has a screen to prevent debris from entering the gauge. It is shipped complete with mounting brackets and 25 ft. of signal cable.
