compressed air and a variety of other gases in wet air or high mass flow
/ velocity applications. The sensor can even work in wet and dirty gases
such as the outlet of a compressor.
The S430 can measure the following parameters for compressed air or
gases:
Parameter Factory default unit
Velocity m/s
Volumetric flow m3/h
Pressure bar
Total consumption m3
Temperature °C
Remark: You can change units by means of the service App S4C-FS,
the optional local display, or the optional service kit.
The S430 flow sensor is mainly used in compressed air systems in the

8.1 Installation requirements
To install the sensor, a ball valve or a nozzle with the following
specifications is needed:
•The inner thread must be G 3/4”.
•The diameter of the hole must be ≥ 18 mm, otherwise the shaft
can not be inserted in.
16 S430

8 Installation
8.2 Determining the installation point
To achieve and maintain the accuracy stated in the technical data, the
sensor must be inserted in a straight pipe section with unhindered flow
characteristics.
8.2.1 Inlet and outlet sections
Unhindered 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, and so on.
Make sure that enough space e ists at your site for an adequate
installation as described in this manual.
TTENTION!
Wrong measurement may occur if the sensor is not
installed correctly.
•Pay careful attention to the design of the inlet and outlet sections.
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.
NOTE: If there is any combination of the following situations, the
longest straight inlet section must be maintained.

•E pansion •Reduction
•90° Bend •2×90° Bend
•3 dimensional Bend •T-piece

8 Installation
•Shut-off valve •Filter or similar (unknown
objects)
8.2.2 Insertion angles
Insertion into a horizontal pipe
As shown in the left figure, the
angle to the horizontal level must
be >10°. A horizontal installation
is NOT permitted.
Please install the sensor only in
the recommended area.
S430 19

8 Installation
Insertion into a vertical pipe
As shown in the left figure, S430
can be used in a vertical pipe
when the following two conditions
are met:
•The flow direction is from bottom
upwards.
•The sensor is installed with an an
angle of at least 10-degree.
(Recommended angle is 20
degrees).
TTENTION: Do not install the
sensor in vertical pipes where the
flow is from top down.
8.3 Calculating the insertion depth
Generally, the sensor tip must be placed in the center 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.
Remark: If the pipe diameter is greater than the shaft length, it is
feasible to install the sensor out of center of the pipe. For more
information, please contact the manufacturer.
