Dimensional drawing
Installation
The inline flow sensors SS43 are built „in-line“ into a pipe line. The pipe may be
connected directly via the cutting ring threaded connection or via a matching adapter. The
adapters come as accessories for a transition from ø10 mm to G1/4 or ø18 mm to G1/2. In order
to achieve the best accuracy, the sensor has to be installed in such a way that the electrical
connection is opposite to the low direction. The medium has to be free of air pockets and bubbles.
Mounting of the cutting ring threaded connection
If no pipe adapters are installed, a precision-grade pipe that meets the requirements of DIN 2391,
must be used. The pipes must feature the following diameters and wall thicknesses:
SS430020: Ø 10 x 1mm
SS430021: Ø 15 x 1.5mm
SS430022: Ø 18 x 1.5mm
1. Cut pipe to length at a right angle and remove burr.
2. Push couplin nut and clamp and cutting ring, as shown in the dimensional drawing, onto the pipe and
insert pipe into the threaded joint until the shoulder of the fitting is reached.
3. Tighten coupling nut manually and check tube position.
4. Attach screw wrench SW27 to sensor connection and tighten coupling nut with an adeqate tool with 1
¼ turns.
5. Check firm fit of the pipe.
Attention: Please ensure that no shear forces between the two pipe connections are created during
mounting and operation.

Mounting the flow sensor housing
At the housing bottom there are four M4 threaded sockets with a depth of 5 mm. These can be used for
mounting on a base plate etc. Alternatively it is possible to use the accessory mounting panel with the
supplied screws for attachment to the sensor housing. This enables front mounting.
Maintenance
If operated in contaminated or calcareous water, deposits can build up, which may lead to
measuring errors. Thus it may be necessary to clean the section of the sensor through which the liquid
passes. The metal surface may not be damaged.
Operation
The inline flow sensors SS43 have front panel buttons for setting functions and displaying
adjustments. All values are indicated via the 3-digit 7-segment display.
Button [S/-]: After a short press of the button, the set limit value for switch point S is indicated. In the
programming mode,this button can also be used to decrease the indicated value.
Button [mA/+]: After a short press of the button, the actual current value in mA is indicated. In the
programming mode, this button can also be used to increase the indicated value.
Button [FUNC]: After a short press of the button, the measured temperature value in °C is displayed for
approx. 3 s. In the programming mode, this button can also be used to select functions and parameters.
Programming
To enter the programming mode, press buttons [S/-] and [mA/+] for at least 3s until the display starts
flashing. For a short moment the character string [Cod] is displayed. Followed by the number [0], which can
be modified according to the valid access code using buttons [S/-] and [mA/+]. Use button
[FUNC] to select the required parameter. After selection, the parameter is displayed for
approx. 2s, followed by the associated value which can now be modified. During entry
it is automatically verified whether the set parameter is admissible. Two decimal points of the
display will flash to warn against an invalid entry. To terminate programming and save all values
press button [FUNC] for at least 3s until the display stops flashing.

Acces code [Cod]
Without entry of an access code it is not possible to set or modify device parameters. The ex factory
setting is “0”. This value can be modified at the end of the programming menu.
Unit of switching point S [USP]
The switching output S can be used for flow reate or temperature monitoring. Select [°C] ] to activate
temperature control. The value units depending on this switch point will change accordingly.
Switching point [SP]
The switch point S is entered in l/min, or, if required, in °C.
Hysteresis [hs]
The hysteresis is the difference between the switch-on value (which is identical to the programmed switch
point S) and the switch-off value. It is entered in l/min, or, if required, in °C.
Output S
The switching output S can be adjusted either for the NO or NC mode.
Switch-on delay [dS]
If it is not required to update the output signal immediately after the switch point S has been exceeded, this
value can be set in a range from 0…50 s. The signal will then only be updated after the set time has expired,
provided the limit is still exceeded.
Switch-off delay [dr]
If it is not required to update the output signal immediately after the switch point S has been underranged,
this value can be set in a range from 0…50s. The signal will then only be updated after the set time has
expired, provided the limit is still underranged.

Averaging [nFi]
This parameter permits the entry of a value, which defines the time interval during which a
measuring value average is formed. Values between 1…8 s can be entered. A low value will lead to a fast
response, whereas a high value steadies the display of the measuring value.
Medium selection [GLY]
The flow sensor series SS43 is generally suited for monitoring water circuits. If a cooling circuit
contains Glycol (monoethyleneglycol), then this specific contents can be entered as a percentage in
increments of 5%. A possible measuring value deviation is thus compensated.
Reference function [CAL]
With this function, the displayed flow rate value can be modified by ± 25%. This can be useful in order to
adapt the display exactly to a reference instrument.
Reset function
Use the RESET function to set all values back to the ex factory settings. For this, the device must be
disconnected from power. Button [FUNC] is then pressed during re-connection. The character string
[rES]ower. Button [FUNC] is then pressed during re-connection. The character string [ ] is displayed.
Then you will be prompted to enter the access code. Press [FUNC] to confirm the entry and carry out
the reset.
Analog output
The analog output provides a current value that is proportional to the flow rate over the total detection
range. Between 0 l/min and the minimum value of the detection range, the output value is 4mA.
