1OVERVIEW
1.1 SYSTEM DOCUMENTATION AND SUPPORT OF PRODUCT
Read any “Safety Information” or “Safety Warnings and Approvals Information”
documentation provided with the products prior to using.
Please also refer to the document MAN-031-0003 “User Guide: PCorr+ and PermaLog+ -
(Description and uses)”. This provides a description of PCorr+ and PermaLog+ logger
devices, their functions, how they should be physically handled and examples of their
use (e.g. Drive-by Patrol, Lift and Shift, Investigations).
This manual covers the use of the HWM WebCorr app to both set up the logger devices
and collect data from them.
Note: Your phone may show views not identical to the pictures in this manual.
Pictures in the manual were created from screenshots using an Android phone.
Due to the wide variety of phones available to consumers, variations will exist.
Pictures in the manual are therefore presented for guide-lines only.
HWM will release software updates from time to time. These may also cause
changes to the screen presentation and the functionality of the application.
It is recommended that you enable your phone to allow automatic updates of the
WebCorr app.
HWM also provides support of the product by means of a webpage:
https://www.hwmglobal.com/pcorr-support/
Should you have any questions that are not covered by a manual, or Frequently Asked
Questions (FAQs) provided online, please contact the HWM Technical Support team on
[phone], or email [e-mail]
1.2 SYSTEM COMPONENTS
A system is comprised of:
•A set of logger devices (PCorr+ or Permalog+).
•A compatible Patroller unit (e.g. Patroller 4 radio transceiver with Bluetooth).
•A mobile phone.
•The HWM WebCorr app.
•An internet connection (for the mobile phone).
•A DataGate user-account and password
(for the app to function and access the HWM database).
1.3 MOBILE PHONE –SPECIFICATION
The HWM WebCorr app is available on Android-based mobile phones and also on Apple
iPhone mobile phones.

5
Minimum specification of phone:
Android: Android version 5 (Lollypop) minimum.
Device must have Bluetooth, GPS and Internet capability.
Memory (for application): 80MB
Memory (for data): 0.2MB typical per sound file.
Apple iOS: iOS version 8.0 minimum.
Device must have Bluetooth, GPS and Internet capability.
Memory (for application): 80MB
Memory (for data): 0.2MB typical per sound file.
1.4 MOBILE PHONE –SWAPPING ISSUES
Caution: Once a phone has been used by an installer it will contain data.
The installer should continue to use the same phone. Each time the installer
swaps to using a different phone, unless it is handled carefully there is a risk
of creating data issues due to a disruption in the synchronisation of data
between DataGate and the mobile phone.
(See also sections 14.7 and 14.8 regarding misplaced or new phones).
1.5 WEBCORR APP –INSTALLATION
The app is available for Android phones, from the Google “Play Store”.
The app is available for the Apple iPhone, from the Apple “App Store”.
•Search for and locate the HWM WebCorr app.
•Install the app.
•The installed app will have an icon, as shown, when installed.
Occasionally, updates become available at the stores. It is recommended to install these
updates.
1.6 PATROLLER
The app uses a Bluetooth connection to a compatible Patroller (e.g. HWM Patroller 4).
Refer to the Quick Start Guide of the Patroller device for instructions regarding its
safety, installation and use.
To work, the phone must have Bluetooth enabled and it must be connected to the
Patroller (see section 3). Bluetooth radio has a range limit. Keep the phone close to the
Patroller to ensure the Bluetooth radio connection can function.
The Patroller acts a communications relay between the loggers (using a proprietary
radio-link) and the mobile phone (using a Bluetooth radio-link).
The Patroller is battery powered. It must be turned on to use. It can only communicate
to loggers that are within radio range and also have an active radio-link.

1.7 PERMANETWEB -ACCOUNT AND PASSWORD
The WebCorr app operates with HWM’s cloud-based logger database. These are known
as “DataGate” and “PermaNETWeb”. The app uploads its data to this database.
DataGate and PermaNETWeb act as the store and main viewing portal for the data. The
database can be accessed via webpages to view logger locations and results (not
covered in this manual). Other webpages give access to administrative functions (also
not covered in this manual).
A user-account must be used within the phone to give access to the online database.
The account also acts as a security feature, with certain functions of the app hidden (or
disabled) unless the app has recently logged into DataGate. Please contact your system
administrator for the account and password allocated for the user of the phone app.
When the phone app logs in, it receives a token permitting it to be used for a short time.
The app will require the user to log in again once the token expires.
1.8 DATAGATE –GIVING THE APP ACCESS TO LOGGER DEVICES
All PCorr+ and Permalog+ loggers must be registered on DataGate in order for the
WebCorr app to use them. DataGate must be set to give the user of the app the
required permissions to use the loggers.
Note: For a brief description of DataGate, and how to register both the loggers
and also users of WebCorr, see section 13.
There is a security measure within the app, regarding logger data privacy…
The app will ignore any logger devices, or data that it receives from logger devices, that
the user has no permission to use.
Note: If a logger is not appearing on the app it does not imply that it is not functioning
correctly. Check with your system administrator that the logger device is
correctly setup on DataGate for use with your user-account.
1.9 LOGGER –DATA DESTINATION
DataGate and PermaNETWeb webpages are the main viewing portal for logger data.
This implies that the final destination of all logger data is the DataGate system.
The scheme is summarised here…
PCorr+ and Permalog+ logger devices produce measurement data. The logger device
obtains several forms of data, each of which can be considered as a data channel. The
data is meaningless, unless it represents a measurement actually made on the pipe
network. Access to the pipe network is often available through various chambers that
house (and give access to) valves or hydrants. These chambers can be used as an
installation site for a logger device. A site may be one of many in an area or suburb,
with the pipe network interconnecting them. Sites may therefore be collected together
in a group, often referred to as a zone or DMA. Each of these separate entities may be
represented on a database, such as one used by DataGate, which links some of them
to a user of the system.

7
Or, put in reverse order…
•DataGate contains a database.
•A user of Datagate can be linked with multiple DMAs.
•Each DMA can contain multiple sites.
•Each site can have one logger device installed (maximum, at any given time).
•Each logger device can produce multiple channels of data.
•The data of a channel may be a one-off sample, or multiple samples that are
obtained at different times.
The WebCorr app and DataGate are concerned with collecting data from the logger
devices, linking it to the correct site and storing it.
Devices such as PCorr+ and Permalog+ can either be permanently installed or used as a
mobile measuring device.
A mobile logger is time-shared by multiple sites and transferred from one site to
another. The transfer process is known by various terms, including “Lift” and “Shift”.
In the time-share scheme, it is not necessary for a particular logger to be returned to a
previously measured site that requires new data; any equivalent logger may be deployed
to the site for producing new data.
The WebCorr app and DataGate manage the location of the loggers, the data collection
and linking of the data to the correct site. This process relies heavily on the exchange of
data between the WebCorr app and DataGate, in a process known as synchronisation.
Initially, when the app is first installed, DataGate is driving the data exchange and loads
starting-point data into the app. The roles are then reversed… The app drives the data-
exchange and keeps DataGate up to date with any new information.
The phone obtains some initial data from DataGate at each log-in time. This information
includes lists of various parameters, including which logger devices the phone has
access to, what installation sites exist, and which site (if any) a logger is installed at. The
app adds any new information to its internal database.
As the app is put into use, further (newer) information is stored by the phone.
(e.g. New measurements obtained from the loggers and changes in their location of
deployment). Each item of new information is tagged as an unsent data item.
DataGate must be brought up to date with this new information (stored by the app).
This is done as part of the synchronisation process.
Note: It is important to synchronise frequently to avoid loss of data.
Data held within a phone that becomes mis-placed (without it being
synchronised) cannot be recovered.
Some of the data held within the phone is also made visible to users of the app.
This data includes:
•Deployment details (changes of location driven by the app).
•Measurement details (Leak status, Noise Level, Noise Spread) read using the app.
•Sound Recordings obtained using the app.
•Site locations (e.g. via a map display).
