Before installing the Amazon in the field, it is a good
practice to test the system in the shop or lab. This will
help preparations for a successful field install. Power
the Amazon, check communication, purge, and take a
measurement. For basic SDI-12 protocol see the SDI-12
section at the end of this document.
As with any environmental installation, care must be
taken to insure proper installation such that data can be
retrieved in a reliable and accurate manner. The following
summarizes ideas and recommendations for the Amazon
and typical orifice line installations. Additional details can
be found in application note “1005 Orifice Line Installation”
on the WaterLog web site.
When installing the 360252 brass orifice fitting, pipe tape
should be used for the NPT threads (threads that are
screwed into the aluminum block on the Amazon) only.
Securely tighten the fitting into the Amazon. The Ferrell
set should be fitted on an orifice tube with a clean cut as
shown. When tightening the top brass fitting, it should be
finger tight and then adjusted with an additional ¾ turn.
Check for leaks on the fitting using “snoop”.
Amazon Bubbler Installation
Do Don’t
Mount the outlet in still water Do not mount the outlet facing upstream,
downstream, or upwards
Mount the outlet so the last inch is almost horizontal
(slightly downward side exit) Do not allow any portion of the line to be lower than
the exit point or allow goose necks in the orifice line
Try to prevent swells in long runs of orifice line Do not use thin walled tubing, only use USGS
approved orifice line
Use a muffler in more turbulent waters Do not mount outlet in the wake of an obstruction,
bridge peer, etc
