Various dangerous situations
To avoid injury take care:
• to prevent any unintentional power supply switch-on.
• to ensure that installation and maintenance work are carried out by qualified, authorised personnel in possession of the appropriate tools.
• to guarantee a defined or controlled restarting of the process, after a power supply interruption.
• to use the device only if in perfect working order and in compliance with the instructions provided in the instruction manual.
• to observe the general technical rules when installing and using the device.
• not to use the device in explosive atmospheres.
• not to use the device for the measurement of gas flow rates.
• not to use the device in an environment incompatible with the materials it is made of.
• not to use fluid that is incompatible with the materials the device is made of.
• not to subject the device to mechanical loads (e.g. by placing objects on top of it or by using it as a step).
• Do not make any external modifications to the device. Do not paint or varnish any part of the device.

Basic safety information
note
The device may be damaged by the fluid in contact with.
• Systematically check the chemical compatibility of the component materials of the device and the fluids likely
to come into contact with it (for example: alcohols, strong or concentrated acids, aldehydes, alkaline compounds, esters, aliphatic compounds, ketones, halogenated aromatics or hydrocarbons, oxidants and chlorinated agents).
note
Elements / Components sensitive to electrostatic discharges
• This 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 compon-
ents 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
the EN 61340-5-1 and 5-2 norms.
• Also ensure that you do not touch any of the live electrical components.

Description
5. DESCRIPTION
5.1. Area of application
8026, 8036 and 8076 devices are intended to measure the flow rate of liquids:
• 8026 and 8036 flowmeters are used to measure the flow of neutral or slightly aggressive liquids,
• 8076 flowmeters are used to measure the flow rate of viscous liquids such as honey or oil, which are free of
solid particles.
Thanks to one or two fully adjustable transistor outputs, the device can be used to switch a solenoid valve,
activate an alarm and, thanks to one or two 4-20-mA current outputs, establish one or two control loops.
5.2. General description
5.2.1. Construction of the 8026
The 8026 flowmeter comprises:
A: a paddle-wheel flow sensor, the rotation of which generates pulses.
C
Set in rotation by the flow, the 4 permanent magnets integrated in the vanes of the
paddle generate pulses, the frequency of which is proportional to the flow speed of
the fluid. A conversion coefficient specific to each pipe (material and diameter) is
necessary to establish the flow rate value associated with the measurement.
The conversion coefficient (Factor K) expressed in pulses per litre is given in the user
B
manual for the fitting used.
B: an acquisition / conversion module for the process values measured:
• acquisition of the pulse frequency
• conversion of the frequency measured into flow rate units
A
C: a display module with navigation button used to read and/or configure the parameters of the device. The display module is not delivered with all the versions of the
flowmeter but it is available as an accessory.
See chap. 11.

5.2.2. Construction of the 8036
The 8036 flowmeter comprises:
A: an S030 fitting including the paddle-wheel flow sensor.
Set in rotation by the flow, the 4 permanent magnets integrated in the vanes of the
C
paddle generate pulses, the frequency of which is proportional to the flow speed of
the fluid. A conversion coefficient specific to each pipe (material and diameter) is
necessary to establish the flow rate value associated with the measurement.
The conversion coefficient (Factor K) expressed in pulses per litre is given in the user
manual for the fitting used.

A
meters of the device. The display module is not delivered with all the versions of the
flowmeter but it is available as an accessory.

5.2.3. Construction of the 8076
The 8076 flowmeter comprises:
A: an S070 fitting including the flow sensor with oval gears.
Set in rotation by the flow, the magnets integrated in the oval gears generate pulses,
C
the frequency of which is proportional to the volume of fluid. A conversion coefficient
specific to each pipe (material and diameter) is necessary to establish the flow rate
value associated with the measurement.
B
The conversion coefficient (Factor K) expressed in pulses per litre is given in the user
manual for the fitting used.

8.3.3. 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 grounding of the shield of the power supply cable.
→ 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 devices such as pumps or valves, that
are as close as possible to the device.

9.12.1. Transferring data from one device to another

• The software version of the display module is displayed when the display module is turned on.

English
Type 8026- 8036- 8076
Adjustment and commissioning
The data transfer is impossible from a device having an acquisition / conversion module for the process
values measured with a V2 software version to a device having an acquisition / conversion module for the
process values measured with a V1 software version.
• On each device, check the software version of the acquisition / conversion module for the process
values measured, in the menu "Info -> Software -> Versions -> Main".
When transferring data from a device having an acquisition / conversion module for the process values
measured with a V1 software version to a device having an acquisition / conversion module for the
process values measured with a V2 software version, the following data are not transferred:
• the access codes to the menus,
• the wire mode of the outputs (fonction "HWMode").
• Function "DOWNLOAD" is only present if an "UPLOAD" has been successfully carried out.
• Never interrupt a data transfer else the device could be damaged.

indicates a flow rate in volume units/min.
• If the flow rate measured is 1 ≤ volume unit/s ≤ 9999, choose the time unit "/s" so that the display indicates a flow rate in volume units/s.
• If the flow rate measured is 0 ≤ volume unit/min or volume unit/s < 1, the display indicates a flow rate in
volume units/h, regardless of the time unit chosen.
• If the flow rate measured is ≥ 10000 volume unit/h, the display indicates a flow rate 166,66 ≥ volume

The wiring mode is the same for all outputs.
If you choose "sink NPN", the current outputs must be wired in sinking mode and the transistor outputs in NPN

A malfunction in your process or the sensor may be revealed by an out-of-range input frequency.
The function allows for monitoring the sensor input frequency and configure the behaviour of the device if the
parametered ranges are exceeded.
The sensor input frequency f is used to determine the flow Q in the pipes using the formula f = KQ (the K factor
being expressed in pulses/s and the flow rate Q in l/s).
To be warned when the input frequency is out of range:
→ activate monitoring of the sensor input frequency in the function "activate", then
→ enter an input frequency range outside of which the device generates a “warning” event and displays the icons
and .
→ enter an input frequency range outside of which the device generates an “error” event and displays the icons

danger
Risk of injury due to high pressure in the installation.
• Stop the circulation of fluid, cut off the pressure and drain the pipe before loosening the process connections.
Risk of injury due to electrical voltage.
• Shut down and isolate the electrical power source before carrying out work on the system.
• Observe all applicable accident protection and safety regulations for electrical equipment.
Risk of injury due to the nature of the fluid.
• Respect the prevailing regulations on accident prevention and safety relating to the use of aggressive fluids.
Warning
Risk of injury due to non-conforming maintenance.
• Maintenance must only be carried out by qualified and skilled staff with the appropriate tools.
• Ensure that the restart of the installation is controlled after any interventions.
