Installation Manual
1. Supplied Material
Each package contains:
• 1 iPERL device in resp. frequency: 433 MHz / 10 mW or 868 MHz / 25 mW
• manual
• optional connection kits
• NRV with gasket (if ordered)
2. General Instructions
Please read this guide prior to installing iPERL.
iPERL is a metering endpoint designed for use with potable water supplies to
residential, commercial and industrial activities.
iPERL is intended for maintenance-free operation for up to 15 years. IPERL is
hermetically sealed and therefore there is no servicing of the meter required.
The water meter is designed for use with potable water for residential activities.
The meters must be stored in a dry, cool place, free of contamination. Please
make sure that during installation all hygienic standards and recommendations
are respected.
3. Area subject to explosion hazards (ATEX, special variant)
"X" Protection against electrostatic damage
Risk of explosion due to sparking because of electrostatic charge of plastic
parts. If cleaning (e.g. display) is necessary a damp cloth can be used. Never
use a dry cloth!
The ATEX markings ( II 3G Ex ic IIC T6 Gc) and the number of the certificate
of conformity (TÜV-A-TAD19ATEX2802) are printed on the housing.
Explanations: Device group II: Usage outside of mines
Device group 3G with protection level Gc for the usage in zone 2 (rare
occurrence of combustible gases, mists and vapors), explosion group IIC for
all gases and T6 (all temperature classes).
4. Permissible Operating Conditions

• Cold and warm water meter: from 0.1 °C up to 50 °C (70 °C, special
variant)
• Pressure stage: MAP16bar

fixed installation with minimum vibration

commercial

• Climatic environment: -10 °C ≤ Ta ≤ +70 °C provided that a minimum water
flow rate of 100 litre / hour is ensured to prevent freezing
5. Installation Requirements
For preparation of the site and the installation of the meter the directions in
ISO-4064, part 5, need to be mandatory observed.

Ensure that the pipework does not introduce mechanical stresses on the meter
body: checking both alignment of the pipework with the threaded connections
and distance between unions with the meter lay length. If there is mechanical
stress usage of the brackets is recommended. When mounting iPERL onto a
network, ensure contact surfaces are even and clean and use new gaskets.
Torque: tighten iPERL to a minimum torque setting of 20 Nm and a maximum
of 30 Nm. For flanged versions the correct torque is 35 - 40 Nm.
Meters must be installed grounded and tension free, without any mechanical
stress on water pipes, for instance installing meters using a metal
meter bracket with length compensation fittings. In cases where the installation
site is not prepared with these brackets, we recommend the permanent use of
a potential compensator to avoid the negative impact of stray currents (see
also section 6.4 of ISO-4064, part 5) that can be ordered as optional part
from Sensus.
The meter does not need any straight upstream or downstream pipe (U0D0).
1 Installation position: iPERL has been designed to operate, with no impact
on metrological performance, in all installation angles and orientations.
Note: When flow direction arrow is pre-set, it needs to be respected.
2 Please avoid installing iPERL as shown below as a reduction of battery
lifetime could occur.
Keep the valves closed when the premises are vacant. Make sure you close
both valves before and after the meter for safety reasons when installation is
not finished yet or there is no water consumption for a longer period, e.g due
to vacant premises.
iPERL is free of any constraint for upstream or downstream straight pipe
lengths.
Flow direction: iPERL's metrological performance is independent of flow
direction and orientation of the meter can be selected to best suit the
installation conditions. iPERL will detect flow direction when installed and set
the direction indicator accordingly.
Pressure: please ensure that iPERL strictly operates within the pressure rating
printed on the meter body.
All iPERL settings and functions will be automatically and correctly activated
once the flowtube is saturated.
6. Installation Procedure (Volume registration & Flow direction)
STEP1:
1A: Remove iPERL from its packaging and locate any optional component
(filter, non-return-valve (NRV), ...)
1)
In case you need a non-return-valve please consider:

of meter outlet (no gasket required)
4 All other nominal sizes and lengths: NRV installation in the outlet of the
measuring tube using the gasket provided in the delivery.
If you do not use a NRV you can choose any other gasket.
iPERL will display the following symbols:
5 No Volume, no flow and the alarm flag (raised for empty pipe)
2)
1B: Install iPERL according to the most suitable LCD orientation
STEP2:
6 Once installed, open the upstream valve to fill the meter. The alarm flag
disappears after a short while, this indicates that the meter has detected water
in the pipe.
iPERL is now fully operational, although in stand-by mode. At this point, also
the radio transmission is activated which is indicated by a flashing radio
symbol. The meter starts to send out radio telegrams.
STEP3:
7A To activate the "flow direction arrow", ensure a flow above the threshold
of
3 l/h for DN 15
5 l/h for DN 20
8 l/h for DN 25
12.5 l/h for DN 32
20 l/h for DN 40
Both arrows blink to indicate the meter is detecting its forward flow direction.
After reaching the threshold the arrow is set.
It starts to accumulate volume into the three registers forward, reverse and
billing volume. The flowrate will start to be displayed after the first 4 hours of
operation.
When the billing volume register reaches the threshold of
25 l for DN 15
40 l for DN 20
63 l for DN 25 - 40
the meter takes that register with the higher volume accumulated as the
forward register and fixes the flow direction.
From this moment on the flow direction cannot be changed; any flow in the
'wrong' direction will now trigger the alarm flag for 'reverse flow' and will be
counted as reverse volume.
7B When flow direction arrow is pre-set, it will appear immediately on the
LCD. For the first 4 hours of initial operation the flow rate indication is in setup
process and the displayed value is only informative. The actual flow rate will
be displayed after 4 hours of operation.The volume counting operation is not
affected as this is independent from the flow information shown on the display.

8 After the flow direction has been set, data logging starts. The respective
data fields for flow and alarms related to flow (like e.g. leakage, broken pipe)
become active 4 hours after the start of the data logger.
9 IMPORTANT! iPERL does not register the volume if the averaged flowrate
is below:
1 l/h for DN 15
1.6 l/h for DN 20
2.5 l/h for DN 25
4 l/h for DN 32
6.4 l/h for DN 40
7. iPERL Display and Characters
10 After installation is successfully completed the display shows:
• Meter reading and preselected unit
• Current flowrate and preselected unit
• Flow direction
• RF active
11 After the LCD self-test the firmware version will be shown followed by the
alarms:
AL-05 Empty pipe
AL-06 Magnetic tampering
AL-07 Reverse Flow
AL-08 Broken pipe / Leakage
If any of the following graphics is displayed, please contact your supplier:
• Alarm flag + AL-xx (except 05-08, see above)
• Low battery warning
• Test mode
Note: The red lines printed on the display (last 3 digits after the comma) show
the liters and shall help read the display more easily.
8. Disposal
12 This product contains a lithium metal battery. In the interest of protecting
the environment, this battery may not be disposed in household waste after its
period of use. The local and national regulations for environmental protection
are to be considered. The expected lifetime of the battery is shown on the
battery pictogram lasered on the iPERL, e.g. 1241 = Month 12 (December),
Year 41 (2041). The meter should be removed or replaced until this date as
the battery is encapsulated and cannot be removed separately.
1) Australia only: NRV is already pre-installed!
2) "no flow" signal on display not available in Chile
