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.

UTS

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

UTS K02/0522 page 5

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.
