Deploy the loggers to sites without any checks being made (i.e., skip some of the
•
steps listed as optional). A follow-up team is then sent to selected sites to
improve those that have communication problems.
Installation consists of several steps...
Installation sites must be selected. These should have a description and
•
reference number to identify them on DataGate.
Equipment must be available at the installation site to complete the installation.
•
This will include any adaptors or couplings required to connect between the
Hydrophone and the water network valve.
This will also include an antenna. It is possible that several antenna
configurations may need to be tried in order to get a good result. It is useful to
have a variety of antenna types to try.
The installer must activate the logger (using a strong magnet) to take it out of
•
shipping mode.
The user connects a communications cable between the PC and logger. IDT can
•
be used to read current settings from the logger into the computer memory.
Prepare the Hydrophone and couplings for connection to the water valve. Ensure
•
they are suitably clean and sterile. Ensure the bleed valve is closed.
Ensure the valve to which the Hydrophone is being attached is suitably clean and
•
sterile.
Lubricate the connecting surfaces to ensure they do not become permanently
•
bonded.
Fit the Hydrophone to the water valve whilst ensuring any health and safety
•
requirements or work practices for undertaking work on pressurised water pipes
are followed. Undertake a risk assessment prior to commencing work.
Connect the Hydrophone to the logger.
•
The antenna is connected to the logger. The antenna location within the
•
chamber is then determined (this may need to be adjusted later; it is a trial-and-
error process).
(Optional). The user can adjust some of the settings of the logger.
•
Alternatively, leave the logger settings in their factory-set configuration.
(Optional). The user can (whilst the chamber lid is off) make a Call Test to
•
DataGate to verify internet connectivity settings are OK and that data can be
sent.
The lid of the chamber is closed (unfortunately, this degrades the signal with the
•
mobile phone network), and the power-level received from the mobile network
(e.g., CSQ level) is checked. If inadequate, adjustments need to be made to the
antenna position, or the type of antenna used, to find the best CSQ level.
With the lid of the chamber closed (and positions finalised), a further Test Call is
•
made to confirm the logger can send and receive data.
