NOTE : On sites with mixed pipe material always select the longest sample period. So if
you have some 6" and some 8" Metal (less than 500 metre lengths) select 20 seconds.
The recording interval is the gap between the START times of each recording.
e.g. if three recordings of 1 minute each are set to start at 1AM with a recording interval of
1 hour then the start times will be 1am, 2am, 3am. If the recording interval is 15 minutes
then the start times will be 1am, 1:15am and 1:30 am.
Radcom recommends 3 recordings – see explanation below.
The recording interval needs to be set with local knowledge in mind. Think of how long it
takes for a toilet to fill in your local area, and set the recording interval to that time. This
will help reduce the detection of noise which is due to legitimate consumption.
This is also partly the reason why we suggest 3 recordings. If a logger detects a noise
which can be put down to legitimate usage then hopefully on the second or third recording
the usage will have stopped.

Select the sample period.
This is determined by the pipe material and
diameter.

Set the number of recordings
(max 9), and set the recording interval
(between 1 minute and 3 hours)
Some combinations of sample periods and
number of recordings will cause excess
memory usage. This is due to memory size
restrictions in the logger.
