Model TB3 Tipping Bucket Rain Gauge

The HyQuest Solutions Tipping Bucket Rain Gauge is recognized as the world standard for measuring rainfall and precipitation in remote and unattended locations. Based on Australian Bureau of Meteorology specifications, the gauge offers an integrated syphon mechanism which delivers high levels of accuracy across a broad range of rainfall intensities.

The gauge consists of a collector funnel with leaf filter with an outer enclosure complete with quick release fasteners with the base housing the tipping bucket mechanism. The unit includes a dual output 24V DC reed
switch with varistor protection as well as dual rainfall discharge outlets for water collection and/or analysis.

Portable Field Calibration Device (FCD): The FCD effectively enables field technicians to run functional tests and calibrations of any given rain gauge in the field avoiding dismantling of TBRG’s, reducing TBRG downtime and thereby saving time and money.

Heater TB3H: A thermostatically controlled heating element raising the temperature of the interior of the rain gauge, funnel and catch to avoid the freezing of the gauge in cold climates with subsequent loss of precipitation records. (“on” when the ambient temperature drops below +4 °C; “off” below -20 °C or above +5 °C)

Bird Guard: The bird guard prevents wild or feral birds from perching or roosting and thus increases accuracy by stopping bird faeces from dropping inside the gauge funnel.

Pulse Counter CMCbt: The CMCbt is a Bluetooth Pulse Counter that provides an interface between the TBRG’s Reed Switch output and the FCD-App calibration software used in conjunction with HyQuest Solutions’ Field Calibration Device FCD.
