2. INTENDED USE

Use of fittings S030 that does not comply with the
instructions could present risks to people, nearby
installations and the environment.

• The S030 fitting is intended to measure the flow rate
of clean fluids in the piping thanks to its paddle wheel.
The S030 fitting may be combined to an electro­nic module for displaying, monitoring or controlling
the flow rate, or a transmitter fitted with a bajonett
connection.

• Use this fitting in compliance with the specifications
and conditions of commissioning and use given in the
contractual documents, in this user manual and in the
user manual for the device which is inserted into it.

• Safe and trouble-free operation of the fitting depends
on its proper transport, storage and installation, as well
as careful operation and maintenance.

• Only use this fitting as intended.

Restraints

Observe any existing restraints when the fitting is exported.

3. BASIC SAFETY INFORMATION

This safety information does not take into account:

• any contingencies or occurences that may arise during
installation, use and maintenance of the devices.

• the local safety regulations for which the operating company
is responsible including the staff in charge of installation
and maintenance.

Danger due to high pressure in the installation.
Danger due to high temperatures of the fluid.
Danger due to the nature of the fluid.

Various dangerous situations

• Prevent any unintentional power supply switch-on.

• Ensure that installation and maintenance work are
carried out by qualified, authorised personnel in
possession of the appropriate tools.

• Guarantee a set or controlled restarting of the pro­cess, after a power supply interruption.

English

7

Various dangerous situations

• Observe the general technical rules when installing
and using the fitting.

• Use the fitting only if in perfect working order and
in compliance with the instructions provided in the
instruction manual.

• Do not use the fittings in PVC or PP in explosive
atmospheres.

• Do not use this fitting to measure gas flow rates.

• Do not use fluid that is incompatible with the materials
from which the fitting is made.

• Do not use this fitting in an environment incompatible
with the materials from which it is made.

• Do not subject the fitting to mechanical loads (by placing
objects on top of it or by using it as a step, for example).

• Do not make any external modifications to the device. Do
not paint any part of the fitting.

English

note

The fitting may be damaged by the fluid in contact
with.

• Systematically check the chemical compatibility of the
component materials of the fitting 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).

5. DESCRIPTION
Area of application

The S030 fitting is intended to measure the flow rate of clean
fluids in DN6 to DN65 pipes thanks to its paddle-wheel. It
must be combined with an electronic device (indicator, flow
threshold detector or transmitter) which converts the pulse

frequency due to paddle-wheel rotation.
The electronic device can be removed without opening the

piping or stopping the process.

Measuring principle

The fluid flowing in the piping makes the paddle-wheel turn.
The paddle-wheel rotational frequency f is proportional to
the flow rate.

English

6. TECHNICAL DATA
Conditions of use

The fluid temperatures and pressures may be
restricted by the electronic device mounted on the
fitting: refer to the relevant manual.

Ambient temperature depends on the device mounted

on the S030. Refer to the relevant
manual.

Pressure class PN16 (or PN40 on request) for metal

fittings.
PN 10 for plastic fittings, depends on

fluid temperature, see Fig. 1.

Fluid temperature depends on the material from which

the S030 fitting and the paddle-wheel
are made, see the following table.

K factors (pulse/litre)

The K factors have all been determined under the following
reference conditions: fluid = water, water and room tem­peratures of 20°C, minimum upstream and downstream
distances respected, appropriate pipe dimensions.

If the S030 fitting is combined with an electronic
device which does not automatically convert the
K factors, make the conversion using one of the
following formulae:

K factor in pulse/US gallon = K factor in pulse/litre
x 3.785 to obtain a flow rate value in US gallon/
time unit
K factor in pulse/UK gallon = K factor in pulse/litre
x 4,546 to obtain a flow rate value in UK gallon/
time unit

English

27

Two versions of the S030 in DN15 and DN20
exist, having different K factors.

Only version 2, identified by the "v2" marking, is
available from March 2012. The "v2" marking can
be found:

• on the bottom of the DN15 or DN20 fitting in
plastic:

• on the side of the DN15 or DN20 fitting in metal:

7. INSTALLATION
Safety instructions

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.

English

31

32

danger

Risk of injury due to high fluid temperatures.

• Use safety gloves to handle the fitting.

• Stop the circulation of fluid and drain the pipe before
loosening the process connections.

Risk of injury due to the nature of the fluid.

• Respect the prevailing regulations on accident pre­vention and safety relating to the use of hazardous
products.

Warning

Risk of injury due to non-conforming installation.

• Fluidic installation can only be carried out by qualified
and authorised personnel with the appropriate tools.

• Observe the installation instructions for the measuring
device inserted into the fitting.

Risk of injury due to an uncontrolled restart.

• Ensure that the restart of the installation is controlled
after any interventions on it.

English

33

Warning

Risk of injury if the fluid pressure/ temperature
dependency is not respected.

• Take into account the fluid pressure/ temperature
dependency according to the materials from which the
fitting is made and to the measuring device used (see
the relevant user manual).

• Comply with the Pressure Directive 97/23/EC.

→ Select an appropriate fitting regarding to the flow

velocity and the flow rate of the fluid in the piping, see
the following charts:

The graph is used to determine the DN of the pipe and the
fitting appropriate to the application, according to the fluid
velocity and the flow rate.

English

33

34

Selection example:

- Specification: if the nominal flow is 10 m

3

/h the dimen­sioning of the optimal flow rate must be contained in 2 to
3m/s

- Answer: on the chart, the intersection of flow rate and
flow velocity gives the appropriate diameter, DN40 or
DN50 for fittings with *.

* For fittings:

- with external threads according to SMS 1145,

- with weld-ends according to SMS 3008, BS 4825 /
ASME BPE or DIN 11850 Rg2

- Clamp according to SMS 3017 / ISO 2852 or BS 4825 /
ASME BPE or DIN 32676

Installing a fitting with weld ends

Follow the previously described general installation
recommendations.

note

The seal on the fitting with weld-end connections
may be damaged during welding.

→ Before welding the weld-ends, unscrew the 4 tigh-

tening screws.

→ Remove the sensor holder.
→ Remove the seal.
→ Weld the weld-ends.
→ After welding, correctly replace the seal in the

groove.

→ Replace the sensor holder.
→ Tighten the 4 screws in an alternating pattern, app-

lying a nominal tightening torque of 1,5 Nm.

English

40

Installing a Clamp fitting

→ Make sure the seals are in good condition.
→ Place seals adapted to the process (temperature,

fluid type) in the grooves of the Clamp fitting.

→ Fix the Clamp fitting to the pipe by means of a clamp collar.

Installing a flange fitting

→ Make sure the seals are in good condition.
→ Place seals adapted to the process (temperature,

fluid type) in the grooves of each connection.

Make sure the seal remains in the groove while
tightening the flange.

→ Tighten the flange to fix the fitting to the pipe.
