2. Note
Please read these operating instructions before unpacking and putting the unit
into operation. Follow the instructions precisely as described herein.
The instruction manuals on our website www.koboldusa.com are always for
currently manufactured version of our products. Due to technical changes, the
instruction manuals available online may not always correspond to the product
version you have purchased. If you need an instruction manual that
corresponds to the purchased product version, you can request it from us
free of charge by email (info.@koboldusa.com) in PDF format, specifying the
relevant invoice number and serial number. If you wish, the operating
instructions can also be sent to you by post in paper form against an applicable
postage fee.
The devices are only to be used, maintained and serviced by persons familiar
with these operating instructions and in accordance with local regulations
applying to Health & Safety and prevention of accidents.
When used in machines, the measuring unit should be used only when the
machines fulfil the EC-machine guidelines.
as per PED 2014/68/EU
In acc. with Article 4 Paragraph (3), "Sound Engineering Practice", of the
PED 2014/68/EU no CE mark.

3. Instrument Inspection
Instruments are inspected before shipping and sent out in perfect condition.
Should damage to a device be visible, we recommend a thorough inspection of
the delivery packaging. In case of damage, please inform your parcel service /
forwarding agent immediately, since they are responsible for damages during
transit.
Scope of delivery:
The standard delivery includes:
Plastic Flow Meter model: KSK
4. Regulation Use
Any use of the Plastic Flow Meter, model: KSK, which exceeds the
manufacturer’s specification, may invalidate its warranty. Therefore, any resulting
damage is not the responsibility of the manufacturer. The user assumes all risk
for such usage.

5. Operating Principle
Kobold Plastic Flow Meters and Switches, model KSK, are based on the well-
known suspended float principle.
They are used for measuring and monitoring flows in closed pipes.
The media flows, from below, through a conical plastic measuring tube. This
raises the float and the flow rate can be read off against scale. The instruments
can be fitted with bistable switches.
Special advantages
Shock resistant and corrosion-resistant
May be inserted/removed radially
Special scales available
Short installation length
Plastic float and fitting generally made of PVDF
6. Mechanical Connection
Before Installation:
Remove all transportation safety locks and ensure that no packing material
remains within the unit.
Be sure that the maximum allowable operating pressure and temperature is
not exceeded (see Technical Data).
Install the flow meter in the piping system, ensure the instrument is under no
mechanical stress/tension (install support bracing if necessary).
Protect the measuring tube from external damage.
Avoid pressure peaks in the measuring tube, e.g. from sudden surges or
stoppage of flow.
The units with bistable reed switch may not be installed within an inductive
field.
If possible, immediately after making mechanical connections, check whether
the connections are properly sealed with no evidence of leakage
(see section 8 Operation).
Detailed information regarding installation of float flow meters is
available in VDI/VDE guidelines 3513.

7. Electrical Connection
7.1. Reed Contact, bistable (option)
Make sure that the supply wires are de-energized.
Loosen the plug-cap holding screw and remove the cap from the switch
housing.
Connect the supply lines inside the plug in accordance with the connection
diagram opposite.
If the set point has not yet been adjusted, it may be done at this point. (see
section 8. Operation).
Set the plug to the socket and fix it with the safety screws.
Attention! The stated electrical parameters of the contact may not
be exceeded, even for a short period of time. For inductive or
capacitive loads, we recommend the use of contact protection
measures respectively the application of a contact protection relay.

7.2. Electronic Contact (option)
Make sure that the supply wires are de-energized.
Loosen the plug-cap holding screw and remove the cap from the switch
housing.
Connect the supply lines inside the plug-in accordance with the connection
diagram opposite.
If the set point has not yet been adjusted, it may be done at this point. (see
section 8. Operation).
Set the plug to the socket and fix it with the safety screws.
Attention! The stated electrical parameters of the contact may not
be exceeded. For inductive or capacitive loads, we recommend the
use of contact protection measures respectively the application of a
contact protection relay.
After connecting the external devices, and adjusting the switch housing to the
desired switch points, all the connection work is completed. The unit is ready for
operation.

8. Operation
In order to initialise the bistable switching function, it is essential
that the float activates the contact once in each direction.
Adjustment of limit-values
The switch-point can be adjusted to the desired levels by using both red sliders
as reference points.
Reference edge for falling flow: bottom-edge, switch housing
Reference edge for rising flow: approx. 5 mm above the bottom-edge of switch
housing.
Slide the switch housing up or down until the reference edge coincides with the
desired switch-point scale reading.
Hysteresis
Hysteresis is the difference between the level at which “switch-on” occurs during
rising flow and the level at which “switch-off” occurs during decreasing flow. The
hysteresis is approximately 5 mm on the float range.
Overranging
With non-pulsating flow, the maximum flow rate can be exceeded. Only an
increase in pressure loss will result (max. permissible operating pressure must
not be exceeded!)
9. Maintenance
If the medium to be measured is clean, the series KSK is virtually maintenance-
free. If deposits form on the inner housing or parts, periodic cleaning of the unit is
recommended. Remove the units from the piping with a suitable tool; clean the
flow meter with a suitable cleaning agent or make use of an ultrasonic bath.
