TIPPING BUCKET FLOW GAUGE MODEL TB1L
I. GENERAL
The HyQuest Solutions Flow Gauge is used for measuring water flowing out of pipes or
drains. The unit comes with a dual reed switch assembly, thus, when connected to a HyQuest
Solutions data logger, the data can be stored and collected when required. In addition, the
flow gauge can be telemetered by connecting one of the HyQuest Solutions data loggers to a
GSM or Satellite.
Event logging with our Data Logger (Optional)
Telemetry options available on request
Connect to display Counter (Optional)

Note: Please ensure that the pipe diameter does not exceed the 75mm (2.5”) and is installed
in the centre of the flow gauge as shown in figures above.
DIAGRAM 2
Note: It is advisable to have a vented cover above the collector of the flow gauge to avoid
water loss at high flow rates and in windy conditions.

i. Site Selection
Water Flow measurements are intended to be representative of the actual water running out of
the pipe. Some of the more important factors which influence the representativeness of a
gauge are as follows:
Site the gauge on a level surface.
Site should have adequate protection from strong winds.
Water coming out of the pipe should not contain any particles that
could block the collector.
Provide suitable ground surface to avoid splashing into the gauge.
ii. Setting up
Install the gauge on a suitable bracket or shelf, as suggested in
Diagram 1,2 & 3.
The gauge is provided with a level. Proceed to level by ensure the
bracket the gauge is mounted on is level
Connect lead to the Flow gauge 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.
VI. MAINTENANCE
The only routine maintenance required is cleaning. The following items should be checked
regularly for cleanliness:
Collector area
Interior of bucket
Top surface of adjusting screws
Lubrication of the pivot using (WD40 or equivalent)

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 Flow Gauge is critical to flood warning etc.
Note: 2x Digital inputs with maximum capacity of 24 Volts (0.5amp max.). They operate
simultaneously to two different RTU’s (example Data logger & Satellite modem)
