3 RF Exposure Information and Statement
3 RF Exposure Information and Statement
This equipment complies with FCC RF radiation e posure limits set forth
for an uncontrolled environment. This equipment should be installed
and operated with minimum distance of 20 cm between the radiator and
your body.
This device complies with part 15 of the FCC rules. Operation is subject
to the following two conditions: (1) this device may not cause harmful
interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
NOTE: The manufacturer is not responsible for any radio or TV
interference caused by unauthorized modifications to this equipment.
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
this equipment does cause harmful interference to radio or television
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.

The S415 is the thermal mass flow meter that is designed to measure
the volumetric flow and consumption of compressed air and nitrogen
within the permitted operating parameters. (See Technical Data on the
ne t page.)
The default unit settings are: volumetric flow in l/min and total
Consumption in m3. Other units can be configured using the mobile App
S4C-FS, which can be downloaded from the Google Play store or SUTO
website. For more information, see chapter 10 on page 25.
5 Features
•Inline thermal mass flow meter virtually independent of pressure
and temperature changes
•Process connection G-type thread, DN8, DN15, DN20, DN25 and
DN32
•Integrated flow conditioner, no need of straight inlet sections
•Very short response time
•Particularly suitable for measuring at point-of-use flow and
consumption of compressed air or N2
•Integrated display showing volumetric flow
•Choices of output signals:
◦Analogue 4 … 20 mA and pulse output
◦Modbus interface
◦M-Bus interface
•Bluetooth interface for device settings
