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.kobold.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
([email protected]) 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:
Variable area flow meter model: UTS
4. Regulation Use
Any use of the device, 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
The Kobold UTS model flowmeter/monitor works on the basis of the suspended
float principle. It is used for measuring the flow rates in closed pipe line systems.
The medium flows from below through a glass measuring cone that gets wider on
top. Thus, the float is raised and indicates the respective flow rate on the scale
provided on the measuring cone.
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.
If possible, immediately after making mechanical connections, check whether
the connections are properly sealed with no evidence of leakage

7. Operation
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!)

8. Maintenance
If the medium to be measured is clean, the series UTS 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.
