Please read these operatinginstructions before unpacking and putting the unit
intooperation.Follow theinstructionspreciselyas described herein.
The instruction manualson ourwebsitewww.koboldusa.comare alwaysfor
currentlymanufactured version of ourproducts. 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 itfrom us
free of charge by email ([e-mail])in PDF format, specifyingthe
relevantinvoicenumberandserial number. If you wish,the operating
instructionscan also be sentto you by post in paper form against an applicable
postage fee.
Thedevices are only to be used, maintained and serviced by persons
familiar withthese operating instructions andinaccordance withlocal
regulations applyingto Health& Safety andpreventionofaccidents.
When used in machines, the measuring unit should be used only when
the machinesfulfiltheEC-machineguidelines.

3. Regulation Use
Any use of the Plastic Flow Meter, model: KSM, which exceeds the
manufacturer’s specification,may invalidate its warranty. Therefore, anyresulting
damage is not the responsibility of the manufacturer. The user assumes all risk
for such usage.

KSM

4. Operating Principle
The Plastic Flow Meter model: KSM operates according to the variable area
principle, in which the float is free to move without friction inside the measuring
tube. The reading edge corresponds to the larger diameter of the float. The
standard flow meter is equipped with a scale for water (+20°C), a percentage
scale, O-rings, 2 adjustable set-point indicators and a rail for accessories; on
each end, two threaded cap-screws accommodate various connectors (see
Section 9: Technical Data; Connections). For the operation with bistable reed
switchesthe floatwill be suppliedwith internal magnets.
5.Instrument Inspection
Instrumentsare inspectedbeforeshipping and sentoutin 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.
Scopeof delivery:
The standard deliveryincludes:
•Plastic Flow Meter model: KSM
6.Mechanical Connection
Before Installation:
•Remove all transportation safety locks andensurethat nopackingmaterial
remainswithintheunit.
•Be sure that themaximum allowableoperatingpressureand temperature is
not exceeded (see TechnicalData).
•Install the flowmeter in the pipingsystem, makingcertain the instrumentis
undernomechanical stress/tension (install supportbracing if necessary).
•Protect the measuring tubefrom external damage.
•Avoidpressure peaks in the measuringtube,e.g. from sudden surgesor
stoppage of flow.
•The unitswith bistablereed switch may not be installedwithinan inductive
field.
•If possible, immediately after makingmechanical connections,checkwhether
the connectionsareproperly sealed with noevidenceof leakage.
Detailed information regarding installation of float flow meters is available
in VDI/VDE guidelines 3513.

7.Electrical Connection
Reed contact, bistable (option)
•Ensurethatthe electrical supplylinesare
disconnectedfrompower.
•Loosen the plug-capholdingscrew andremove the
cap from theswitch housing.
•Connectthesupplylinesinsidetheplug-capin
accordancewith the connection diagramopposite.
•If the set pointhasnot yet been adjusted, it may be
doneat thispoint. (see section 8, 'Operation').
•Set the plug to the socket andfix it with the safety
screws.
Attention! The stated electrical parameters of the reed switch may not be
exceeded, even for a short period of time. For switching higher power
ratings, we recommend a contact protection relay (e.g. our model MSR) or
any other interposing 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-travel 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 referencepoints.
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-pointscalereading.
Hysteresis
Hysteresis is the differencebetween thelevelat which “switch-on”occursduring
rising flow and the level atwhich “switch-off” occurs during decreasing flow. The
hysteresis is approximately 5 mm on the float scale.
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!)

11. Maintenance
If the medium to be measured is clean, the series KSM is virtually maintenance-
free. If deposits form on theinnerhousing orparts, periodic cleaningof theunit is
recommended. Remove the units from the piping with a suitable tool; clean the
flowmeter with a suitablecleaningagentormake useof an ultrasonicbath.
If using the setpoint switch, it is particularly important to guard against
contamination byferritic(metal) contaminants.Thesecan be eliminatedby using
the KOBOLD model MF magnetic filter (or equivalent).
