RIM8000 Commercial Grade Rain Gauge
Services Available
Repair Yes
Calibration Yes
Free Support Yes

Overview

The RIM8000 series is a commercial grade rain gauge that uses the same tipping bucket and siphon assembly as the RIM7499 series but with a spun aluminium base and a spun copper collecting funnel and rim. The RIM8000 is accurate to within /- 3% at intensities up to 380mm per hour and /- 5% at rates up to 500mm per hour. Can be ground mounted or mounted on galvanised pipe using Campbell Scientific’s CM240 rain gauge mount. Other bucket sizes are available on request.

Detailed Description

The RIMCO 8000 series rain gauge utilises the bucket and siphon assembly of the high performance RIMCO 7499 series to ensure accuracy and a long service life but at a lower cost. All materials used are corrosion resistant and designed for almost all environmental conditions. The RIMCO 8000 is accurate to within 3% up to 380mm/hr and 5% up to 500mm/hr. Rain falling on the 203mm (8”) diameter collecting funnel is directed through a siphon control unit and discharges as a steady stream into a precision two compartment bucket mounted in unstable equilibrium. As each compartment fills the bucket tilts alternately about its axis. Each tilt produces a momentary contact closure as a result of a magnet sweeping past a reed switch assembly. Each contact closure corresponds to 0.2mm, 0.25mm or 0.5mm of rainfall according to bucket capacity. An individual calibration certificate is supplied with every RIM8000 rain gauge.
