2. Application
The S430 is a flow sensor which is designed to measure the
consumption of compressed air and gases in wet air or high mass flow /
velocity applications. The sensor can measure in wet and dirty gases as
occurring, for example, at the outlet of a compressor.
The S430 can measure the following values:
•Velocity of the compressed air or gas.
•Volume flow of the compressed air or gas.
•Total consumption of the compressed air or gas.
•Pressure and Temperature of the compressed air or gas.
The default factory settings are: Velocity in m/s, Volume flow in m3/h
and Total Consumption in m3, pressure in bar, temperature in °C. Other
units can be programmed by the optional display or the service kit.
The S430 flow sensor is not developed to be used in explosive areas.
For the use in explosive areas please contact the manufacturer.
The S430 flow sensor is mainly used in compressed air systems in
industrial environment.

6. Installation
Before you install the sensor, make sure that all components listed
below are included in your package.
Qty Description Item No.

1 Sealing ring No P/N
1 Alignment key No P/N
2 M12 plug C219 0059

1 Calibration certificate No P/N
6.1 Installation equirements
To install the sensor a ball valve or a nozzle is needed.
•The inner thread has to be G 1/2”.
•The diameter of the hole must be ≥ 13mm otherwise the shaft
can not be inserted.8.2 Installation Procedure
6.2 Determination of the installation point
In order to maintain the accuracy stated in the technical data, the
sensor must be insert in the centre of a straight pipe section with
unhindered flow characteristics.
emark
If the pipe diameter is higher than the maximum shaft length, it is
possible to install the sensor out of centre of the pipe. For this please
contact the manufacturer.
nhindered flow characteristics are achieved if the section in front of
the sensor (inlet) and behind the sensor (outlet) are sufficiently long,
absolutely straight and free of obstructions such as edges, seams,
curves etc..
Please consider that enough space exists at your site for a adequate
installation as described in this manual.
S430 13

6. Installation
ATTENTION!
Wrong measurement is possible, if the sensor is not
installed correctly.
•Careful attention must be paid to the design of the inlet and outlet
section. Obstructions can cause counter-flow turbulence as well as
turbulence in the direction of the flow.
•The sensor is for indoor use only! At an outdoor installation, the
sensor must be protected from solar radiation and rain.
6.2.1 Inlet and outlet sections
L1 : Length of inlet section
L2 : Length of outlet section
D : Diameter of tube
Please keep at least 8 x D upstream and 3 x D downstream to ensure
an significant influence to the measuerement due to up and
downstreampipe bends.

6. Installation
6.2.2 Insertion angles
Please install the sensor only in
the recommended area like you
can see in the picture. A horizontal
installation is not permitted.
Please consider that the distance
to the horizontal level must be
>10°.
Installation in a vertical pipe is
possible, required the flow is from
bottom up and the sensor has at
least a 10 degree angle
(recommended is 20 degree).
ATTENTION: Do not install in
vertical pipes if the flow is from top
to down.
S430 15

6.3 Calculating the insertion depth
Generally, the sensor tip must be placed in the centre of the pipe. To
facilitate this, the sensor is designed with a scale engraved on its shaft.
To determine the right position, calculate the insertion depth as
described below.
Note: If the pipe diameter is greater than the shaft length, it is feasible
to install the sensor out of centre of the pipe. For more information,
please contact the manufacturer.
6.3.1 Centre installation
Centre installation is the default and recommended installation type.
Insertion depth=x+y
x=OD
2; OD=Outer diameter of pipe
Example for a 2” pipe and a 87 mm ball valve:
y=87 mm ; OD=60.3 mm
x=OD
2
=60.3 mm
2
=30.15 mm
Insertion depth=30.15 mm+87mm=117.15 mm
16 S430

6.3.2 Non-centre installation
In bigger pipe diameter (> DN150) situations, the non-centre
installation is applicable. In the non-centre installation, the sensor is
inserted to exact 100 mm-depth of pipes.
Insertion depth=x+y+100
x is the wall thickness of pipes
Example for a 12” pipe, the wall thickness of pipes 9 mm and a 87 mm
ball valve:
x=9 mm ; y=87 mm
Insertion depth=9 mm+87 mm+100 mm=196 mm
S430 17

6.4 Installation of the sensor
First please observe the flow direction
indicated on the housing or on the shaft. It
must match the flow direction of the
compressed air or gas.
1. Ball valve has to be closed.
2. The sensor head has to be completely
covered by the connection thread (see
photo on the left).
3. nderlay the “O-ring” at the thread of
the ball valve before screwing the flow
sensor.
4. Screw the connection thread tightly to
the ball valve and align flow sensor to flow
direction.
5. Open ball valve and tighten clamp
sleeve manually by hand.
6.Perform zero flow calibration (see
picture on P21).
7. Move flow sensor slightly to the
determined insertion depth by means of
the scale.
8. Tighten the clamp sleeve at the
connection thread so that the flow sensor
can not longer be moved by the pressure
in the pipe, however it should be possible
to move the sensor shaft manually.
9. With the aid of the alignment key make
sure that the actual flow direction is same
as the arrow shows (the angle deviation
should not be larger than ± 2° to the
perfect position, please see picture on the
next page).
10. Tighten clamp sleeve with clamping
torque 20...30 Nm.
11. During the final check control the
installation depth again because sometimes
the shaft is moved from its original position
due the compressed air.

6.5 Performing the zero flow calibration
The zero flow calibration is a compulsory operation during the
installation of the sensor. se one of the following methods to perform
the calibration:
•The service App S4C-FS, available on the Google Play store or our
Website for free download
•The optional local display
6.5.1 Prerequisites
Before you start the calibration, make sure the following conditions are
met:
•The sensor must have been mounted on top of the G 1/2" ball
valve.
•The ball valve must be opened with the sensor tip outside of the
pipe. That is, the sensor tip still remain inside the ball valve.
These ensure that the sensor is exposed to the system pressure during
calibration.
6.5.2 Using the service App S4C-FS
This is the most convenient way especially when the sensor is not
equipped with the optional local display.
1. On your mobile device, download the S4C-FS App from the
SUPPO T > Downloads menu on https://suto-itec.com or from
Google Play store as needed.
2. Turn on Bluetooth on your mobile device.
3. Launch the S4C-FS App.
S430 19

Sensors that are within the reach of your Bluetooth signal while not
connected with other S4C-FS Apps are displayed on the home
screen.
Note: A red Wireless Connection icon is displayed behind a
connected sensor, which indicates that the sensor is
successfullyconnected but accessible in the read-only mode. In this
mode, you can only view the online parameter values and existing
settings.
4. Click the Scan Q Code button, and then scan the QR code
provided on the calibration certification.
A green Wireless Connection icon is displayed indicating that the
sensor is accessible in the editable mode.
Note: Only through scanning the QR code can you edit system
settings and perform calibrations.
5. Click the System icon.
On the System screen that appears, click Calibration and follow
the onscreen instructions to perform the zero flow calibration.
