4 pplication
The S430 flow sensor is designed to measure the consumption of
compressed air and a variety of industrial gases in wet 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 Default unit
Velocity m/s
Volumetric flow m3/h
Pressure bar
Total consumption m3
Temperature °C
Remark: You can change units using the service App
S4C-FS or the optional sensor display.
The S430 flow sensor is mainly used in compressed air systems in the
industrial environment. The S430 is not designed for e plosive areas.
For the use in e plosive areas, please consult the manufacturer.

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

8 Installation
8.2 Installation considerations
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!
The wrong measurement might 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.
Remark: If there is any combination of the following situations, the
longest straight inlet section must be maintained.

•90° Bend •2×90° Bend
•Three 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 installed in a vertical pipe
when the following two conditions
are met:
•The flow direction is from bottom
to top.
•The sensor is installed with a
horizontal angle of at least 10-
degree. (Recommended angle:
20-degree).
TTENTION: Do not install the
sensor in vertical pipes where the
flow is from top to bottom.
8.3 Calculating the insertion depth
Generally, you must insert the sensor tip in the center of the pipe with
the help of the sensor shaft that has a scale engraved. To determine the
right position, calculate the insertion depth as described below.
