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.

7 Determining the installation point
7 Determining the installation point
In order to maintain the accuracy stated in the technical data, the
sensor must be insert in the center of a straight pipe section with
unhindered flow characteristics.
Unhindered flow characteristics are achieved if the section in front of the
sensor (inlet) and behind the sensor (outlet) are sufficiently long,
absolutely straight and free of obstructions such as edges, seams,
curves etc..
Please consider that enough space exists at your site for an adequate
installation as described in this manual.
ATTENTION!
rong measurement is possible, if the sensor is not
installed correctly.
•Careful attention must be paid to the design of the inlet and outlet
section. Obstructions can cause counter-flow turbulence as well as
turbulence in the direction of the flow.
•The sensor is for indoor use only! At an outdoor installation, the
sensor must be protected from solar radiation and rain.
•It is strongly recommend not to install 401 permanently in wet
environment as it exists usually right after a compressor outlet.
S401 13

8 Reserving inlet and outlet sections
8 Reserving inlet and outlet sections
Because the thermal measuring principle may be sensible to inlet and
outlet conditions, we recommend the following minimum straight inlet
and outlet sections be reserved to ensure an accurate measurement.
The 401 sensors should be always installed upstream from obstacles
like valves, filter, reductions etc. In common, sensors should be
installed as far as possible away from any disturbances.
Note: If there is any combination of the below, the longest straight inlet
section must be maintained.
•Expansion •Reduction
•90° Bend •2 x 90 ° Bend

9.1 Installation requirements
To install the sensor, a ball valve or a nozzle is needed.
•The inner thread must be G 1/2”.
•The diameter of the hole must be ≥ 13 mm, otherwise the shaft
can not be inserted.
16 S401

9 ensor installation
9.2 Installation procedure
The following steps explain the procedure of an appropriate installation.
9.2.1 Calculating the installation depth
Center installation is the default and recommended installation method.
The sensor tip must be placed in the center of the pipe. The meter shaft
has a scale engraved. To determine the right position, please calculate
the insertion depth as described below.
Insertion depth=x+y
x=OD
2;OD is Outer Diameter of the pipe
y=length of the ball valve
Calculation example:
A 2”-diameter pipe and an 87 mm-
length ball valve:
OD=60.3 mm
x=OD
2=60.3 mm 2=30.15 mm
y=87 mm ;
Insertion depth
= 30.15 mm +87 mm=117.15 mm
S401 17

Sensor installation
For bigger pipe diameters (>200 mm), the sensor can be installed with
only a 100 mm insertion depth as the alternative. This allows one
sensor to be used for all pipe sizes.
Note: The 100 mm installation method requires a setting through the
4C-F app or the service software.
Insertion depth=x+y+100
x is the all thickness of pipe
y = length of the ball valve
Calculation example:
A 12”-diameter pipe with the wall
thickness of 9 mm and a 87 mm-
length ball valve.
x=9 mm ; y=87 mm
Insertion depth
= 9 mm+87 mm+100 mm=196 mm
18 S401

9 ensor installation
9.2.2 Installing the sensor
First please observe the flow direction
indicated on the housing or on the shaft. It
must match the flow direction of the
compressed air or gas.
1. Ball valve hast to be closed.
2. The sensor head must be completely
covered by the connection thread (see
photo on the left).
3. Underlay the “O-ring” at the thread of
the ball valve before screwing the flow
sensor.
4. crew the connection thread tightly to
the ball valve and align flow sensor to flow
direction.
5. Open ball valve.
6. Move flow sensor slightly to the
determined insertion depth by means of
the scale.
7. Tighten the clamp sleeve at the
connection thread so that the flow sensor
can not longer be moved by the pressure
in the pipe, however it should be possible
to move the sensor shaft manually.
8. With the aid of the alignment key make
sure that the actual flow direction is same
as the arrow shows (the angle deviation
should not be larger than ± 2° to the
perfect position, please see picture on the
next page).
9. Tighten clamp sleeve with clamping
torque 20 … 30 Nm.
10. During the final check control the
installation depth again because sometimes
the shaft is moved from its original position
due the compressed air.
S401 19

Sensor installation
Maximum angle deviation of a proper installation:
9.2.3 Removing the sensor
1. Hold the flow sensor.
2. Release the clamp sleeve at the connection thread.
3. Pull out the shaft slowly until the value “10” can be read at the
scale.
4. Close the ball valve.
5. Release the connection thread and unscrew the flow sensor.
