3 RF exposure i formatio a d stateme t
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

4 Application
4 Applicatio
The S418-V is a thermal mass flow sensor that is designed to measure
the actual flow at the low pressure side of vacuum pumps within the
permissible operating parameters (in chapter 6 Technical data).
The S418-V can measure the following values:
•Absolute volumetric flow (default unit: al/min)
•Total consumption (default unit: m3)
•Absolute pressure (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 at the low
pressure side of vacuum pumps.
•Integrated display showing actual volumetric flow and absolute
pressure.
•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
