Funnel Tube
Funnel Filter Kit
The internal funnel tube that directs water to the tipping buckets may need cleaning, use a pipe
cleaner or small nylon bristle wire brush or similar part to insert into the pipe to clean it
Clean or replace the gauze filter into the filter tube and replace the top cap (see spare part 1723-
PK-114).
Remove and clean any dirt from the tipping buckets, being careful not to tip the bucket should the
rain gauge still be logging.
Check that the gauge is still level. It is possible for the gauge to become tilted as a result of small
ground movements, vandalism etc.
There will be times when for one reason or another the rain gauge will be not logging or will be
disconnected from the logger, during these times it is a good idea to check the balance arm of the
bucket for stiffness. The easiest way to do this in the field is to try and balance the bucket in its
centre position, it should be very difficult if not impossible to achieve this, if the bucket balances
easily then examine the bucket closely for any dirt or wear on the pivot pin and bucket tubes. Any
wear will require the unit to be repaired/replaced.
