3 RF exposure information and statement
Such modifications could void the user’s authority to operate the
equipment.
NOTE: This equipment has been tested and found to comply with the
limits for a Class B digital device, pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment
generates uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If

reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or
more of the following measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and receiver.
•Connect the equipment into an outlet on a circuit different
from that to which the receiver is connected.
•Consult the dealer or an e perienced radio/TV technician for
help
•This device and its antenna(s) must not be co-located or
operating in conjunction with any other antenna or transmitter.

4 Application
4 Application
The S418 is the thermal mass flow sensor that is designed to measure
the consumption of compressed air and other gases within the
permissible operating parameters. (These parameters are stated in
chapter 6 Technical Data).
The S418 can measure the following parameters:
•Volumetric flow (default unit: l/min)
•Total consumption (default unit: m3)
•Pressure of the fluid (optional) (default unit: bar)
Other units are configurable using the service App S4C-FS, which can be
downloaded from the Google Play Store or our Website. For more
information see chapter 10.
5 Features
•Inline thermal mass flow sensor virtually independent of pressure
and temperature changes.
•Process connection of G-type thread with DN8, DN15, DN20 and
DN25 available
•Very short response time.
•Particularly suitable for measuring at the point-of-use flow and
consumption of compressed air and other gases.
•Integrated display showing volumetric flow.
•Options for output signals:
◦Analogue 4 … 20 mA and pulse output
◦Modbus interface
◦M-Bus interface
•Bluetooth interface for remote sensor settings
•Configurable through Android devices
•Embedded Data logger capable of recording 5-million
measurement samples
