Description
5 DESCRIPTION
5.1 Area of application
The device is intended to measure the flow rate of liquids:
• Type 8026 and Type 8036 flowmeters are used to measure the flow of neutral or slightly aggressive liquids,
• Type SE36 flow transmitter with a Type S070 or a Type S077 sensor-fitting is used to measure the flow rate of
viscous liquids such as honey or oil and 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 Construction of the Type 8026
The Type 8026 flowmeter comprises:
A
C
B
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 velocity
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 (K-factor) expressed in pulses per litre is given in the
Operating Instructions of 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
C: an electrical housing which can include a display module. The display module
has a navigation button to read and/or configure the parameters of the device. The
display module is not delivered with all the device variants of the flowmeter but is
available as accessory. Refer to chpt. 11.
5.3 Construction of the Type SE36
The Type SE36 flow transmitter comprises:
A
B
A: an acquisition / conversion module for the process values measured:
• acquisition of the pulse frequency
• conversion of the frequency measured into flow rate units
B: an electrical housing which can include a display module. The display module
has a navigation button to read and/or configure the parameters of the device. The
display module is not delivered with all the device variants of the flowmeter but is
available as accessory. Refer to chpt. 11.

Description
5.4 Construction of the Type 8036
The Type 8036 flowmeter comprises:
A
B
A: a Type S030 sensor-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 velocity
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 (K-factor) expressed in pulses per litre is given in the
Operating Instructions of the sensor-fitting used.
B: a Type SE36 flow transmitter. Refer to chpt. 5.3.
5.5 Construction of the Type SE36 with a Type S070 or
a Type S077 sensor-fitting
The Type SE36 flow transmitter with a Type S070 or a Type S077 sensor-fitting comprises:
A
B
S077
S070
A: a Type S070 or a Type S077 sensor-fitting including the flow
sensor with oval gears.
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 pipe
(material and diameter) is necessary to establish the flow rate
value associated with the measurement.
The conversion coefficient (K-factor) expressed in pulses per litre
is given in the Operating Instructions of the sensor-fitting used.

7.1 Safety instructions
Danger
Risk of injury due to electrical voltage.
▶Before carrying out work on the system or the device, disconnect the electrical power for all the conductors
and isolate it.
▶If the device is installed either in a wet environment or outdoors, all the electrical voltages must be of max.
35 V DC.
▶All equipment connected to the device shall be double insulated with respect to the mains according to the
standard UL/EN 61010-1.
▶Observe all applicable accident protection and safety regulations for electrical equipment.
Risk of injury due to pressure in the installation.
▶Before any intervention in the installation, stop the circulation of fluid, cut off the pressure and drain the pipe.
▶Before any intervention in the installation, make sure that there is no pressure in the pipe.
▶Observe the dependency between the fluid temperature and the fluid pressure.
Risk of burns due to high fluid temperatures.
▶Use safety gloves to handle the device.
▶Before opening the pipe, stop the circulation of fluid and drain the pipe.
▶Before opening the pipe, make sure that the pipe is completely empty.
Risk of injury due to the nature of the fluid.
▶Respect the prevailing regulations on accident prevention and safety relating to the use of dangerous fluids.
Warning
Risk of injury due to non-conforming installation.
▶The electrical and fluid installation can only be carried out by qualified and skilled staff with the appropriate
tools.
▶Install appropriate safety devices (correctly rated fuse and/or circuit-breaker).
▶Respect the installation instructions for the fitting used.
Risk of injury if the dependency between the fluid pressure and the fluid temperature is not respected.
▶Observe the dependency between the fluid temperature and the fluid pressure for the device. Refer to
chpt. 6.6.
▶Observe the dependency between the fluid temperature and the fluid pressure for the fitting used. Refer to
the Operating Instructions of the fitting used.
