Model TB7 Tipping Bucket Rain Gauge

HyQuest Solutions’ TB7 is a new generation high-quality tipping bucket rain gauge for measuring rainfall and precipitation in remote and unattended locations when used in conjuction with HyQuest Solutions’ Undercover data logger (see flip side) or a smart communication module. TB7 is a reliable ‘low cost’ device with a very good accuracy across a broad range of rainfall intensities.

The TB7’s tried and proven design ensures long-term, accurate and repeatable results. It is manufactured from high quality, durable materials ensuring long-term stability in the harshest of environments. Enclosure and base consists of robust UV-resistant ASA polymer, and fasteners and filter are made of stainless steel.

TB7 provides a finger filter that ensures the collector catch area remains unblocked when leaves, bird droppings and other debris find their way into the catch.
The TB7’s base incorporates two water outlets at the bottom allowing for water collection and data verification.

Maintenance of the TB7 is easy, because removal of the outer enclosure and access to the tipping bucket mechanism and finger filter assembly is made easy with quick release fasteners.

Output options

TB7 includes a dual output 24 V DC reed switch allowing for output redundancy or the addition of a second data logger. The reed switch incorporates varistor protection against surges that may be induced on long, inappropriately shielded signal cables.

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 TBRGs, reducing TBRG downtime and thereby saving time and money.


iRIS Undercover datalogger:

The compact unit facilitates installation within HyQuest Solutions’ raingauge enclosures. The single communication slot supports either a wireless 3G or 4G modem (SDI-12 optional). The iRIS Undercover provides a Wi-Fi hotspot that enables access to the device wirelessly using HyQuest Solution’s free-of-charge iLink software.


Autonomous System RainTrak Undercover:

TB7 can be used as a component of the RainTrak to provide a reliable and autonomous real-time rain monitoring and reporting system. Features: turnkey operation, battery operated with solar panel, integrated undercover IP-capable data logger, periodic or event-driven data communication, wireless communication, incl. antenna, custom designed for harsh environments.
