flow/velocity applications. The flow meter 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 flow meter display.
The S430 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.

The minimum flow rate depends on the medium pressure and the cut-
off setting. Below chart shows the relationship at 20 sm/s cut-off and
at 30 sm/s cut-off. The cut-off e factory is to 20 sm/s.
Remark: The total consumption value is saved to the permanent
memory every 5 minutes. If within these 5 minutes the device is
powered off, it will restore the last consumption value which was saved
in the last cycle.

8. Installation Requirements
To install the flow meter, 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
flow meter must be inserted in a straight pipe section with unhindered
flow characteristics.
8.2. Inlet and Outlet Sections
Unhindered flow characteristics are achieved if the section in front of the
flow meter (inlet) and behind the flow meter (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.
ATTENTION!
The wrong measurement might occur if the flow
meter 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 flow meter is for indoor use only! At an outdoor installation,
the flow meter 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.

8 Installation
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 flow meter only
in the recommended area.
Insertion into a vertical pipe
As shown in the left figure, the
S430 can be installed in a vertical
pipe when the following two
conditions are met:
•The flow direction is from bottom
to top.
•The flow meter is installed
with a horizontal angle of at
least 10-degree.
(Recommended angle: 20-
degree).
ATTENTION: Do not install the
flow meter in vertical pipes where
the flow is from top to bottom.
S430 19
8 Installation
8.3 Calculating the Insertion Depth
Generally, you must insert the sensor tip in the center of the pipe with
the help of the flow meter shaft that has a scale engraved. To determine
the right position, calculate the insertion depth as described below.
8.3. Center Installation
Center installation is the default and recommended installation type.
Insertion depth=x+y+100
x is the wall thickness of pipe
y = Height of the ball valve
Calculation e ample:
A 2”-diameter 、pipe and an 87 mm-
height ball valve:
OD=60.3 mm
OD
2=60.3 mm
2=30.15 mm
Height of Valve=87 mm ;
Insertion depth
= 30.15 mm +87 mm=117.15 mm
