TIPPING BUCKET RAINGAUGE MODEL TB3
I. GENERAL
The Hyquest Solutions Tipping Bucket Raingauge (TB3) is recognised as the standard for
measuring rainfall and precipitation in remote and unattended locations. The TB3 raingauge
operates on the tipping bucket principle, and can be supplied with two types of bucket
assemblies; Painted Metal (Brass) or Chrome Plated ABS (Plastic). A receiver of 200mm
diameter collects the rainfall, which then flows through the Stainless Steel Catch Filter into
the Syphon Mechanism before being passed into the tipping bucket measuring system. One
tip of the bucket will occur when the calibrated resolution of precipitation is collected (either
0.2, 0.5, 1.0mm or 0.01 inch). When the bucket tips, it will pass the encapsulated Dual Reed
Switch assembly that detects these events and produces a momentary contact closure signal
for:
logging into our of precipitation Rainfall Data Logger, Model ML1-FL
telemetered rainfall systems such as the RainTrak, Model, Model RT-
3G
displayed on our Total Rainfall Display (TRD).
II. UNPACKING YOUR TB3 RAINGAUGE

Important Notice:
The 6 plastic washers are supplied with each rain gauge for the following reasons:
1- Avoid scratching the paint on the base and expose the base to an external harsh and
corrosive environment.
2- Avoid the stainless steel bolt and washers from damaging the paint on the aluminium
base and creating galvanic corrosion between stainless steel and aluminium.
Please note:
Stainless Steel bolts and nuts are part of the Mounting Plate Part No. TB334. This part is
supplied as an accessory and not part of the rain gauge kit.

i. Site Selection
Rainfall measurements are intended to be representative of the actual rain falling on a given
area. Some of the more important factors which influence the representativeness of a gauge
are as follows:
Site the gauge on level ground where possible. Avoid sloping sites.
Site should have adequate protection from strong winds.
Site should be free of large obstructions such as buildings and trees.
Provide suitable ground surface to avoid splashing into the gauge.
ii. Setting up
Install the gauge on the foundation. A suggested foundation is detailed
in Diagram 1.
Loosen the three enclosure securing screws and the enclosure.
The gauge is provided with a level. Proceed to level by adjusting the
hold down anchors as required.
Connect lead to the raingauge terminals, in accordance with Diagram
3, and to the recording device, in accordance with manufacturer’s
instruction manual.
V. TEST OPERATION
Manually tip the bucket a number of times, ensuring that each tip is
being recorded and that the tilting mechanism is operating freely.
Replace and secure the enclosure.

VII. ELECTRICAL
Dual reed switches are provided for several reasons:
Two isolated switches permit the control of two separate circuits; e.g. a
local counter and a telemetry circuit.
Parallel connection of both switches increases the current carrying
capacity of the contact system if required.
Parallel switch operation confers a degree of redundancy in locations
where data from the raingauge is critical to flood warning etc.
VIII. CALIBRATION
All gauges have been calibrated by Hyquest Solutions Pty Limited prior to despatch.
The following products and services are available from Hyquest Solutions Pty Ltd.:
Field Calibration Device, Model FCD, for routine field check calibrations,
supplied with operating instruction sheet.
Laboratory Calibration Unit, Model TB340, for calibration after servicing in
workshops, supplied with operating manual.
Recalibration Service at Hyquest Solutions’ factory.
