Description
5 DESCRIPTION
5.1 Area of application
The transmitter 8025 Universal can be connected to a remote flow sensor which emits a frequency signal. The
specifications of the flow sensor which can be connected to the transmitter are described in chapter “6 Technical
data”.
When connected to a flow sensor, the device makes it possible to switch a solenoid valve, activate an alarm or
generate a flow rate proportional frequency, thanks to a transistor output and, for some versions, by means of two
relay outputs, fully configurable, and to establish a control loop thanks to a 4-20 mA current output.
5.2 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.
5.3 Available versions
The following versions of transmitter 8025 Universal are available.
All these versions have a 4-20mA current output (AO1), a transistor output (DO1) and two totalizers.

danger
Risk of injury due to electrical voltage.
▶Shut down the electrical power source of all the conductors and isolate it before carrying out work on the
system.
▶Observe all applicable accident protection and safety regulations for electrical equipment.
Insert the supplied stopper gaskets into the unused cable glands of a wall-mounted version to ensure the
tightness of the device.
Only move the selectors when the power supply is off.
• Use a filtered and regulated 12-36 V DC power supply.
• Make sure the installation is equipotential. See chap. “7.4.1”.
• Use shielded cables with a temperature limit of 80 °C minimum.
• Do not install the cables near high voltage or high frequency cables; If this cannot be avoided, observe a
min. distance of 30 cm.
• Protect the device power supply by means of a 300 mA fuse and a switch.
• Protect the power supply of each transistor output by means of a 125 mA fuse.
• Protect the relays by means of a max. 3 A fuse and a circuit breaker (depending on the process).
• Do not apply both a dangerous voltage and a safety extra-low voltage to the relays.
7.4.1 Equipotentiality of the installation
To ensure the equipotentiality of the installation (power supply - device - fluid):
→Connect together the various earth spots in the installation to eliminate the potential differences that may
occur between different earthes.
→Observe faultless earthing of the shield of the power supply cable, at both ends.
→Connect the negative power supply terminal to the earth to suppress the effects of common mode currents. If
this connection cannot be made directly, a 100 nF/50 V capacitor can be fitted between the negative power
supply terminal and the earth.
→Special attention has to be paid if the device is installed on plastic pipes because there is no direct earthing
possible. Proper earthing is performed by earthing together the metallic instruments such as pumps or valves,
that are as close as possible to the device. If no such instrument is near the device, insert metallic earthing
rings inside the plastic pipes upstream and downstream the device and connect these parts to the same
earth. The earth rings must be in contact with the fluid.
