Mounting the Rain Gauge
The rain gauges tipping bucket mechanism is immobilised before shipping to
prevent damage in transit. To release the mechanism, remove the funnel from its
base by unscrewing the three nylon thumbscrews. Remove the piece of foam from
under the bucket mechanism. This foam may be saved and used whenever the
rain gauge is moved.
The MetPak RG mounting arrangement options: -
Baseplate Mounting
Due to the low weight of the rain gauge (1kg approximately) it must be mounted
securely, the use of the Baseplate is recommended for this. However the gauge
may be mounted via the three holes in the base to a paving slab for example. It is
suggested that rawlbolts are used for this purpose as they provide a means of
levelling the rain gauge.
Unscrew the 3 upper nylon thumb nuts and remove all the nylon spacers from the
studs.
Lift off the tipping bucket base assembly to leave the metal baseplate and studs.
Fix the baseplate to level ground using the 4 pegs provided through the 4 corner
holes. The baseplate may be mounted to hard surfaces like concrete by replacing
the 4 supplied pegs with screws and rawlplugs.
For temporary mounting on hard surfaces use some bricks or heavy weights on the
four corners of the baseplate (the height of the weights should be kept as low as
possible to cause the minimum interference with the aerodynamics of the rain
gauge).
Refit the tipping bucket base assembly.
Refit the nylon spacers over the 3 studs.
Loosely screw on the 3 nylon thumb nuts.
