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.
Operating instructions, data sheet, approvals and further information via the QR
code on the device or via www.kobold.com
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 Machinery Directive.
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:
 Ultrasonic Flowmeter/ -Monitor/ -Counter/ -Dosing Unit model: DUK

4. Regulation Use
Any use of the device, which exceeds the manufacturer’s specifications, 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
5.1 General
The new KOBOLD type DUK flow meters are used for the measurement,
monitoring, metering and dosing of low viscosity aqueous fluids.
The devices work on the principle of the difference in running times.
This is based on the fact that ultrasonic waves in a medium are influenced by the
speed of flow.
Two sensors mounted opposite one another in the pipeline function
simultaneously as transmitter and receiver of ultrasound signals.
If there is no flow, then the running times of both signals are identical. If the
medium is flowing, then the running time of the signal against the flow is longer
than that with the flow.
The running time difference, which is determined by a microprocessor, is
proportional to the speed of flow.
The devices can be equipped with a switching output, a frequency output or an
analogue output. A universal compact electronics model C3T0 is also available,
which contains two outputs that can be configured as required by the customer.

6. Mechanical Connection
6.1 Check operating conditions
 flow rate
 max. operating pressure
 max. operating temperature
In general, the DUK is subjected to the same loads as the piping into which it is
installed. The DUK should therefore be kept free from extreme loads, such as
pressure surges with strong, dynamic pipe movements, vibrations in the proximity
of centrifugal pumps, high temperature media, flooding etc.
6.2 Installation
 Remove all packing materials and transport retainers and ensure that no such
materials remain in the device.
 It can be installed in vertical, horizontal or rising pipes. Flow in direction of the
arrow.
 Avoid pressure and tensile load.
 Mounting the inlet and outlet pipe in a distance of 50 mm from the connections.
 Avoid valves or large reduction on the inlet section (this increases the
inaccuracy of measurements).
 Check the leak tightness of the connections.
 Air bubbles in the flowing medium can disrupt the measuring function or
reduce measuring accuracy

7. Electrical Connection
7.1 General
Attention! Make sure that the voltage values of your system
correspond with the voltage values of the measuring unit.
 Make sure that the supply wires are de-energised.
 Connect the supply voltage and the output signal to the plug PIN´s as stated
below.
 We recommend the use of wires with cross sectional area of min. 0,25 mm².

8.2 Use of media other than water (only option -C3T0)
The DUK-...C3T0 is able to measure viscous media up to a maximum viscosity of
68 mm2/s. However, this must be a homogeneous Newtonian liquid, but not
necessarily based on water. The DUK-...C3T0 is factory set with a data set for
water. If another medium is to be used, the KOFICOM-IFMU order option and the
free MEDIATOR Tool software are required to exchange the data set.
MEDIATOR Tool contains the data records of common media and is regularly
expanded with media data. Upon request, customer-specific data sets can be
created upon submission of the relevant data.
The MEDIATOR Tool software can be downloaded free of charge from the
Kobold homepage: www.kobold.com/qr/DUK
9. Adjustment – Compact Electronics DUK-...C3T0
The operation and setting of the electronics option -C3T0 is described in the
operating manual supplement for C3T0.
