Tipping Bucket Rain Gauge - Solar

DETAILS

Precipitation is collected in a funnel and measured by the calibrated tipping bucket. For each 0.254 mm (.01") of precipitation, the bucket tips, empties, and activates an output switch. The tipping bucket rain gauge is available in either an aluminum or polypropylene bucket construction and with both ground and tower mounting options.

The Tipping Bucket Rain Gauge | NL configuration mounts via three mounting legs with 6.3 mm (.025") diameter holes on a 241 mm (9.5") diameter circle. The ground mount kit includes 7 m (24') of cable as well as the mounting platform and pipe to install this sensor next to your meteorological tower.
