Please check if this instruction manual accords to the
product type.
Please observe all notes and instructions indicated in this
manual. It contains essential information which must be
observed before and during installation, operation and
maintenance. Therefore this instruction manual must be read carefully
by the technician as well as by the responsible user / qualified
personnel.
This instruction manual must be available at the operation site of the
flow sensor at any time. In case of any obscurities or questions,
regarding this manual or the product, please contact the manufacturer.
ARNING!
Compressed air!
Any contact with quickly escaping air or bursting
parts of the compressed air system can lead to
serious injuries or even death!
•Do not exceed the maximum permitted pressure range (see the
sensors label).
•Only use the pressure-tight installation material.
•Avoid that persons get hit by escaped air or bursting parts of the
instrument.
•The system must be pressure-less during maintenance work.
ARNING!
Voltage used for supply!
Any contact with energized parts of the product, may
lead to an electrical shock which can lead to serious
injuries or even death!
•Consider all regulations for electrical installations.
•The system must be disconnected from any power supply during
maintenance.
•Any electrical work on the system is only allowed by authorized
qualified personal.

2 RF exposure information and statement
This equipment complies with FCC RF radiation exposure 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.
uch 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 experienced 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.

3 Application
3 Application
The 401 is a flow sensor that is designed to measure the consumption
of compressed air and gases within the permissible operating
parameters. These parameters can be found in the technical data
section.
The 401 can measure the following values:
•Volumetric flow of the compressed air or gas.
•Total consumption of the compressed air or gas.
The default factory settings are: Volumetric flow in m3/h and Total
Consumption in m3. Other units can be available by configuration using
the 4C-F android app, the optional display or the service kit.
The 401 flow sensor is mainly used in compressed air systems in
industrial environments. The 401 flow sensor is not developed to be
used in explosive areas. For the use in explosive areas please contact
the manufacturer.
4 Features
•Insertion type flow sensor for easy installations under pressure
through a ball valve.
•Thermal mass flow measurement, virtually independent of
pressure and temperature changes.
•IP65 casing provides robust protection in the industrial
environment.
•Very fast response time.
•High accuracy and wide measuring ranges. pecial ranges on
request.
•Tube diameters from 1/2” up to 12”, larger diameters on request.
•Optional display directly on the sensor, showing volumetric flow
and consumption.
•Modbus interface (optional).
