Basic safety information
3 BASIC SAFETY INFORMATION
This safety information does not take into account any contingencies or occurrences that may arise during instal-
lation, use and maintenance of the device.
The operating company is responsible for the respect of the local safety regulations including for the staff safety.
Danger due to electrical voltage.
▶If a 12...36 V DC energized version is installed either in a wet environment or outdoors, all the electrical volt-
ages must be of max. 35 V DC.
▶Before carrying out work on the system, disconnect the electrical power for all the conductors and isolate it.
▶All equipment connected to the device must be double insulated with respect to the mains according to the
standard IEC 61010-1:2010.
▶Observe all applicable accident protection and safety regulations for electrical equipment.
Various dangerous situations
To avoid injury:
▶Do not use the device in explosive atmospheres.
▶Do not use the device in an environment incompatible with the materials it is made of.
▶Do not subject the device to mechanical stress.
▶Do not make any modifications to the device.
▶Prevent any unintentional power supply switch-on.
▶Only qualified and skilled staff can carry out the installation and maintenance work.
▶Guarantee a defined or controlled restarting of the process, after a power supply interruption.
▶Observe the general technical rules.
NOTICE
Elements / Components sensitive to electrostatic discharges
The device contains electronic components sensitive to electrostatic discharges. They may be damaged if they
are touched by an electrostatically charged person or object. In the worst case scenario, these components are
instantly destroyed or go out of order as soon as they are activated.
▶To minimise or even avoid all damage due to an electrostatic discharge, take all the precautions described in
standard EN 61340-5-1.
▶Also ensure that you do not touch any of the live electrical components.

Description
5 DESCRIPTION
5.1 General description
The 8025 Universal is a flow transmitter with display, available in wall-mounted and panel versions:
• The panel version is made up of an electronics integrated in an open housing with display.
• The wall-mounted version is made up of an electronics integrated in a housing with cover, display and 3 cable
glands.
The device is equipped with a 4...20 mA current output (analogue output, called AO1), a transistor output (con-
figured as a pulse output by default, called DO1) and two totalizers.
Some versions are also fitted with two relay outputs (called DO2 and DO3).
The device operates on a 3 wire system and needs a 12...36 V DC or a 115/230 V AC power supply.
The electrical connection is carried out on the terminal blocks of the electronic board.
5.2 Description of the rating plate
LFLOW 8025 PANEL SUPPLY: 12-36V= 210 mA
DO1: 5-36V= 100mA AO1:4-20mA
DO2&3: 2xRelay 30 and 42V peak or 60V... max. IP20
