fulfillment of all the requirements of modern water management
systems, through a flexible and hybrid electronics which,
depending on the model, offers various power supply solutions.
An electromotive force is induced at the ends of a conducting
fluid that moves with velocity vin a magnetic induction field 
and can be expressed as:

Where:
■is constant by construction;
■Dis constant and represents the distance between
the electrodes E1 and E2 (equivalent to the diameter
of the flow meter);
■vis the fluid velocity;
■kis the calibration constant.
The electromotive force «e» is proportional to the speed
«v».

2.5 Power batteries
The FLC-608B and FLC-608R converters are battery-
powered via a primary lithium battery as well as a
rechargeable lithium battery.
It is therefore necessary to consider that lithium batteries
are the primary energy source because of their high-energy
density, and are created to meet the highest safety
standards. However, they can be potentially hazardous
if they are exposed to electrical or mechanical abuse.
In many cases, this is associated with excessive heat
production in which the increased internal pressure could
lead to cell rupture.These basic precautions need to be
followed when handling and using lithium batteries:
WARNING! IMPORTANT INSTRUCTIONS
▶Do not short-circuit, recharge, overload or
reverse-connect the battery.
▶Do not expose the battery to temperatures
higher than those specified, as it will
incinerate.
▶Do not crush, puncture or open the cells
or disassemble the battery packs.
▶Do not weld or braze the battery body
or battery packs.
▶Do not expose the contents to water.
The use of lithium batteries is regulated under the United
Nations Model Regulations on the Transport of Dangerous
Goods (UN Model Regulations on the Transport of
Dangerous Goods), document ST/SG/AC.10/1 Rev. 20.
These are basic precautions that should be followed during
the transport of lithium batteries:
IMPORTANT NOTES!
▶Transport only in special packages with labels
and special transport documents specific to
current regulations.
▶Be careful when handling, transporting
and packing the batteries so as to avoid
short-circuiting.
▶The batteries comply with the requirements
set out in the “UN Manual of Tests and
Criteria, Part III, subsection 38.3” for air
transport and with the provisions of the ADR
regulations for transport by truck/ship.
WARNING! IMPORTANT INSTRUCTIONS
Remove the battery from the transmitter before
sending the flow meter to Euromisure in case
of maintenance or any intervention under
warranty.

2. Product description
2.6 Data safety
All versions of the FLC-608 converter guarantee safety of
the collected and processed data as a result of the internal
memory (EEPROM) on which the data are saved.
The integrated circulating memory allows the storage of data
with 200,000 log lines.The data are kept for more than 6
years with factory settings. When the memory is full, the new
data will automatically overwrite the old data.
In order to prevent the loss of saved data, and to be able
to better manage it on its management systems, the unit
is supplied with a specialized software that allows users to
communicate with the electronics of the FLC-608 via IrCOM
or RS485 Modbus serial interfaces, that can be connected
to any PC, laptop and/or tablet with a Windows Operating
System.
Fast download, data management, easy programming and
an advanced self-diagnosis system, that automatically
perform a wide range of essential checks, make the FLC-608
converter a highly efficient and irreplaceable tool for fluid
detection in water management systems.
A multi-level password system also allows controlled access
to the data collected and guarantees confidentiality.
2.7 Remote data reading
The GSM module allows data collection on site and remote
monitoring via the GSM/GPRS network and permits any
client to access all the information easily and without any
cost. An additional communication module automatically
sends the information via SMS, e-mail (with or without
attachment).
2.8 Optional modules
2.8.1 
The FLC-608A/I converter can be equipped with an optional
module (installable only by the manufacturer) which acquires
the Hart connectivity on the 4-20 mA output, granting the
access to all quantities measured by the device as well as
to the operating parameters. A FLC-608 converter equipped
with Hart connectivity has no Modbus connectivity on RS485.
For more information on Hart, refer to the relevant
documentation.
2.8.2 Optional module Pression/Temperature for
FLC-608A
All the versions of the FLC-608 converter can be equipped
with an optional module (installable only by manufacturer)
to which one or two wired probes are connected, that allow
the device to measure the pressure and temperature of the
process.This information, in addition to being stored in the
internal data logger, can be directly viewed on the display,
is accessible via Modbus / Hart and is transmitted by the
GSM module (if installed) in the manner laid out by the same
device.
