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.

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)

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.

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.

Tool

Electrical safety

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.

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.

This specific tool is required to correctly open and close the case; it matches the locking system
and maintains the product's seal.

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").
