STAINLESS STEEL TIPPING BUCKET RAIN GAGE

Meteorological station

Stormwater management

Rain enters gauge through an eight inch orifice, protected by distortion preventing aluminium ring

Collected water passes through debris-filtering screen and is funnelled into one of two tipping buckets inside the gauge.

When a given amount of water collects, bucket tips (amount determined by calibration).

Tipping causes magnet to pass over proximity switch, closing it momentarily.

Second bucket positions under funnel for filling.

After rain is measured, it exits through drain tubes with screen covered holes in the base of the gauge.
