Functional description
1. Presentation
9 Typical application:
The Data Logger automatically collects the counting and flow values and measures
drinking water network pressure; it sends these data by SMS or GPRS once a day, to a
centralized system.
Powered by a Lithium battery, this product possesses a
power autonomy of several years.
Completely watertight, it conforms to the requirements
of the environment in which it is placed: in particular
when fitted underground, or in a wet or flood-prone
counting manhole.

3. Hardware properties
Case
Dimensions in mm: H = 261 x W = 155 x D = 176
(the case can be wall-mounted using 2 screws)
Input cable connector: watertight bayonet connector (military grade)
Watertightness
With its IP68 protection rating, the Data Logger can be fitted in a wet or flood-prone manhole.
The case is protected against the effects of prolonged submersion, up to 100 days in 1 meter
of water.
Autonomy
The "934" battery (or standard battery) is optimized to provide the Data Logger with an
operating autonomy of several years.
The "933" battery (or high capacity battery) can be used to significantly increase the Data
Logger's autonomy.
Aerial
The built-in GSM aerial has been specifically designed to improve communication quality over
GSM networks in difficult environments (particularly in buried manholes).
An optional external aerial can be connected to the case.
Key
The key enables a user to wake the Data Logger to write the configuration and to run operating
diagnostics (communication tests, meter indexing, GSM reception level check, etc.).
These operating tests can be performed either using the indicator lights, using either
SOFTOOLS in Bluetooth communication mode, or with a mobile phone via SMS.
Tool
This specific tool is required to correctly open and close the case; it matches the locking system
and maintains the product's seal.
Electrical safety
EN 60950 standard:
In accordance with current European regulations, this device is intended for use in an industrial
environment. It presents no hazardous voltage, in accordance with the low voltage directive (for
further details, see § "Environmental standards and conditions").
4. Functional characteristics
Configuration
Configuration read/write via SOFTOOLS via Bluetooth and SMS communication.
Diagnostics
Operating checks and communication tests:
- using the indicator lights,
- using SOFTOOLS in Bluetooth communication mode,
- using a mobile phone in SMS communication mode.
Data acquisition
4 DIs can be configured to manage meters and signaling.
Characteristics of meter inputs:
- minimum pulse duration: 2 ms (max. frequency: 250 Hz).
- for meters with an open collector transistor type output (capacity < 220 pF).
These characteristics apply to products bearing a serial number greater than or equal to 04xxxxxxxx;
for earlier versions, the maximum pulse duration is 20 ms (max. frequency: 25 Hz).
2 optional AIs for acquiring two "4-20 mA" measurements converted to 10 bits for remotely powered
sensors.
Data calculations
Periodical data calculation:
- for daily reports (volumes),
- average flows (values expressed in m3/h),
- nighttime flow to monitor flow over a user-definable time period.
- for thresholds on AI measurements and/or average meter flow rates.
Archiving
Large storage capacity: up to 50,000 values archived.
Periodical archiving of meter indices, average flows and AI measurements (e.g.: every 15 mn).
Daily report archiving (current index, daily volume, min., max. and night flow).
Communication with SCADA Central Stations
The Data Logger communicates with a centralization system whose type can be configured:
SCADA central stations via SMS or GPRS, or with a WEB server via GPRS.
• By SMS: the Data Logger sends archived SMS messages to 1 or 2 SCADA Central Stations. On
a change of state, the Data Logger can instantly send an SMS message of current states and all
the archived SMS messages to the SCADA Central Stations.
• By GPRS: the unit initiates communications with the central system; it can be used on a GPRS
network with a private (or dedicated) APN or a public (standard) one.
On each GPRS communication, the Data Logger sends the central system the archived values
of its data, the daily reports and diagnostic data.
By default, the unit communicates once daily with the centralization system, though in certain cases, for
specific needs, multiple daily transmissions can be programmed (based on configurable times, or
periodically).
Communication with a mobile phone
The Data Logger can send warning messages to the user's mobile phone.
The user can issue Diagnostic commands via SMS messages.
Unit's Installationa
July 2010 – V 2.2 A
1. Watertightness
This unit has an IP68 protection rating; it is fully protected against the effects of immersion
and can be fitted in a manhole in a wet or flood-prone environment. The product's "IP68
watertightness" guarantee implies that the SIM card must be inserted into the case by the
supplier at the time of delivery.

3. Precautions for use
3.1. Opening the case
Tool
The case can be kept watertight by screwing the case ring tightly. The case must not be
opened except for inserting the SIM card or replacing the battery.
To open the case, we recommend:
Case locking
clip
•
locking the case in the "upside down" position, either between your knees, or in a
vise (though care must be taken to avoid damaging the plastic)
•
inserting the tool into the notches provided for this purpose and rotating it
clockwise (in this position, the tightening and loosening directions are reversed).
Proceed similarly to close the case; use the tool to tighten the ring until the clip locks.
Do not tighten beyond the clip.
3.2. Battery power
The Lithium battery may be potentially hazardous; the following recommendations
for use must therefore be followed:
•
Do not recharge, short-circuit, crush or dismantle; do not heat beyond 100°C
or incinerate.
•
Risk of fire, explosion and burns.
To protect the environment, return spent batteries to your supplier for recycling.
When transporting, please conform to the UN standards described in the "Standards
and conditions of use" document for category UN 3091 - Class 9 instruments.
3.3. Optimizing the case position
To improve GSM communications, the unit's position in the manhole must be carefully
considered; it should generally be kept away from the manhole cover. Mount the case
vertically on its bracket, in accordance with the case's Top and Bottom.
The tests should be conducted in a real situation, with the manhole cover closed.
1) The indicator lights on the Remote Terminal Unit provide an initial diagnostic level.
2) SOFTOOLS, in Diagnostics mode, can be used to search for the best operator.
3) The user must find the best position for the case in the manhole using the
"Reception level test" function, via SOFTOOLS in Diagnostics mode, or using a
mobile phone to send a command no. 7 SMS (see § “Configuration and
Diagnostics”).
