1INTRODUCTION AND PREPARATION FOR USE
Thank you for choosing a HWM system. We trust it will provide you with many years of
service.
The Touch Pro series are correlator systems. They are designed to detect leaks within a
pressurised water pipe network. More precisely, they are used for detecting the most
probable location of a water leak. (i.e., To pin-point the leak location).

1.2 SAFETY CONSIDERATIONS
Safety Note:
Before continuing, carefully read and follow the information in the “Safety Warnings
and Approvals Information” document supplied with the product.
This provides general safety information.
Safety Procedures:
Working with water and other fluids under pressure can be hazardous. Recommended
safety procedures for working conditions must be followed at all times, and operational
procedures described in this manual should not take precedence over local safe
working practices or company procedures. If in doubt, ask your local safety officer.
The use of Touch Pro equipment Hydrophone 2 sensor option with the water supply is
subject to the hygiene procedures applicable to any objects coming into contact with
drinking water supplies. Hydrophone sensors and adaptors should be appropriately
sterilised prior to use and applicable procedures should be followed during their
installation.
Use of Touch Pro with other liquids or gases should follow national and company safety
procedures for operation in proximity with these substances.
DO NOT use your hands for installing the sensors in valve/hydrant chambers or meter
boxes without checking for foreign objects. Sharp objects can easily pierce gloves. If
any excavation is required, use suitable tools.
Electrical Safety:
Water pipes are frequently used as the connection for electrical earth. Danger of
electric shock exists with metal pipes when disconnecting meters, etc. An earthing strap
should be fitted between the two ends of the pipe before disconnection.
Sensor Magnet:
The Touch Pro Sensors are equipped with a Neodymium Magnet. This feature allows
the sensor to be connected to any ferrous valve, and to remain stable. This magnet has
been chosen due to its magnetic strength and small size.
The Touch Pro outstations are equipped with a Neodymium Magnet. This feature allows
the outstation to be connected to a ferrous pit lid, and to remain stable even under
high-wind conditions. This magnet has been chosen due to its magnetic strength and
small size.

1.3 OPERATING TEMPERATURE
Refer to the equipment datasheet or your sales representative for guidance on the
storage and operating temperature range of the device. Ensure the equipment is within
its operating temperature range prior to and during use.
1.4 BATTERY INSTALLATION AND CHARGING
Due to shipping regulations, the Touch Pro Base Unit and Outstations are dispatched
with the battery packs packaged separately. All batteries supplied are rechargeable
lithium-ion. The batteries are identical and are interchangeable.
Warning: Do not short-circuit the batteries. Any misuse may result in explosion
or fire. They must not be used in any other application or used with any
other equipment. Only batteries/battery-packs supplied by
HWM-Water Ltd must be used. The sealed battery packs contain circuitry
to prevent overcharging and over discharging.
When delivered, the internal batteries required for the Base Unit and Outstations
will only have a nominal charge and should be fully charged before mobile
operations are undertaken.
To charge the batteries they must first be installed in the equipment.
Tools required: No. 1 Posi bit,
Torque driver set to 0.8 –1.0 Nm
Flat head screwdriver
1.4.1 Base Unit –Battery pack installation
Loosen / remove the Velcro hand
straps from the rear of the unit.
Remove 6 off M3 x 10 Posi
countersunk screws as indicated
using a
No. 1 Posi bit.
Remove the battery cover.
Install and connect the battery.
Replace the battery cover and
secure with 6 off M3x10 Posi
countersunk screws, using a No.1
Posi bit and tighten to 0.8 –1.0
Nm.
Replace / tighten the Velcro hand
straps.
Remove screws x6 here
(Colour of base unit may vary)
Note: Sensors are powered from
the equipment they are
fitted to, and do not contain
batteries.

1.4.2 Outstation Units –Battery pack installation
Remove the 2 off ¼ turn fasteners from the
base of the unit, as indicated, using a flat
head screwdriver.
Remove the battery cover assembly.
Install and connect the battery.
Replace the battery cover assembly.
Tighten the 2 off ¼ turn fasteners on
the base of the unit, using a flat head
screwdriver.
(Repeat the steps above with the second outstation).
1.4.3 Battery charging and storage
Following the battery fitting procedure, the units will require a full charge before use.
All batteries may be charged simultaneously while the components are stored in the
Touch Pro case. The units will charge regardless of their on/off status.
Charging for all batteries takes up to 6 hours from flat, although an overnight charge is
recommended for maximum performance.
When the batteries are fully discharged, they should be recharged within 24 hours.
Provided the above instructions are followed carefully maximum battery life should be
maintained.
Note: If the system is going to be stored for any length of time, to ensure long life of
the batteries it is recommended that they are charged to approx. 1/4 of capacity.
The batteries should be removed from the units during extensive periods of
storage.
Plugging a charger into an outstation that is switched on will automatically switch off the
outstation. This is to prevent the outstation being left on when charging in the case. To
use an outstation while it is charging, please depress the on/off button for 2 seconds to
switch the outstation back on. An outstation will always charge when a charger is
connected and the battery is not full, regardless of whether the outstation is on or off.
Note: When replacing the Outstation battery, please ensure that no USB is connected.
No damage will be done to the unit, but it will cause the outstation to run a
bootloader program.
(This feature is for factory use or maintenance purposes only).

2OVERVIEW
2.1 INTRODUCTION
The Touch Pro is a high-speed leak location system which employs:
•Class-leading sensors.
•A large full-colour touch screen.
•An integrated noise filtering, analysis, and management software.
The equipment package combines to produce accurate survey data using cross
correlation techniques.
Leak correlation is used to find the exact location of a leak on a pipe. Highly sensitive
acoustic sensors are placed at intervals on the pipe. These listen to the sound made by
the leak. The data is transmitted wirelessly from ‘outstation units’ to a handheld ‘base
unit’, which processes the information to identify the leak sound, and then applies
mathematical algorithms to pinpoint the leak position.
This latest model retains all the key features of earlier Touch Pro systems and provides
many new benefits which ensure greater operating flexibility and faster operating
speed.
The Touch Pro system is fully menu driven and is operated by touch screen, making it
much easier to input data and also maximising the visible screen area to display results
more clearly than has ever been possible before.
The Touch Pro has sensitive transducers built into its sensor. This enables it to perform
well even in traditionally difficult conditions, such as on plastic and large diameter
pipes. This can be further extended with the use of the Hydrophone-2 sensor option.
The Touch Pro features a high visibility full colour VGA touch screen to greatly improve
data entry and the quality of data presentation. The touch-sensitive user interface eases
and simplifies leak-finding without compromising on functionality or precision and
enables the unit to be operated with the minimum number of key presses. The large
screen, with anti-glare screen protection, clearly displays correlation results and
supportive information even in bright sunshine, effectively combining outstanding
performance with excellent ease of use.
The system is equipped with an innovative multi-filter correlation option which can
simultaneously perform three correlations at different filter settings. This is particularly
useful when the pipe material is uncertain.
The outstation is compact with high-quality long-range radio transmission; it also
features a magnet to secure onto metallic street furniture.
The purpose designed robust case not only carries and protects all components but
charges them via mains or vehicle supply. The charge level for all items can be shown at
the touch of a button.
