Basic safety information
BASIC SAFETY INFORMATION3.
This safety information does not take into account:
any contingencies or occurences that may arise during assembly, use and maintenance of the devices.•
the local safety regulations that the operator must ensure the staff in charge of assembly and maintenance observe.•
Danger due to high pressure in the installation.
Danger due to electrical voltage.
Danger due to high temperatures of the fluid.
Danger due to the nature of the fluid.
Various dangerous situations.
To avoid injury take care to:
prevent any power supply switch-on.• carry out installation and maintenance work by qualified and skilled staff with the appropriate tools.• guarantee a set or controlled restarting of the process, after a power supply interruption.• use the device only if in perfect working order and in compliance with the instructions provided in the user manual.• observe the general technical rules during the planning and use of the device.•
NOTE
Chemical compatibility of materials in contact with the fluid.
Systematicallycheck thechemical compatibilityof thecomponentmaterials ofthe transmitterand theproducts likelyto 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 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 the EN 100• 015-1 norm.
Also ensure that you do not touch any of the live electrical components.•
This device was developed with due consideration given to accepted safety rules and is state-of-the-art. However, risks
may arise.
Failure to observe these instructions as well as any unauthorised work on the device excludes us from any liability and also
nullifies the warranty which covers the device and its accessories.

Description
DESCRIPTION5.
Area of application5.1.
8026, 8036 and 8076 transmitters are intended solely for the measurement of the flow of liquids:
8026 and 8036 transmitters are used to measure the flow of neutral or slightly aggressive liquids• the 8076 transmitter is used to measure the flow of viscous liquids such as honey or oil, which are free of solid particles.•
Thanks to 1 or 2 transistor outputs, the transmitter can be used to switch a solenoid valve, activate an alarm and, thanks to 1
or 2 4-20 mA current outputs, establish one or two control loops.
General description5.2.
Construction of the 80265.2.1.
The 8026 transmitter comprises:
!
"
#A: a paddle-wheel flow sensor, the rotation of which generates pulses.
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 con-
version coefficient specific to each pipe (material and diameter) is necessary to establish the
flow 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.
B: an acquisition / conversion module for the physical parameters measured:
acquisition of the pulse frequency• conversion of the frequency measured into flow units•
C: a display module with browse button used to read and/or configure the parameters of the
device. The display module is available as an accessory.
See Chapter 12.
Construction of the 80365.2.2.
The 8036 transmitter 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 paddle
generate pulses, the frequency of which is proportional to the flow speed of the fluid. A con-
version coefficient specific to each pipe (material and diameter) is necessary to establish the
flow 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.
B: an acquisition / conversion module for the physical parameters measured:

#
A: an S070 fitting including the oval-wheel flow sensor.
Set in rotation by the flow, the magnets integrated in the oval gears generate pulses, the
frequency of which is proportional to the volume of fluid. A conversion coefficient specific to
each fitting is necessary to establish the flow 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.
B: an acquisition / conversion module for the physical parameters measured:

Fig. 6.5 Fluid pressure / temperature dependency for a transmitter type 8036 (SE36 associated to an S030 fitting with PVDF paddle-wheel)
General data6.3.2.
Diameter of the conduits DN06 to DN400;
For an S020 or S030 fitting, the appropriate diameter is determined
using the flow/DN/fluid speed graphs: refer to the user manuals for the
fittings
