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.
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:
 Low Volume Rotating Vane Flow Meter model: DPL
4. Regulation Use
Any use of the DPL 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 flow meters models DPL are used to measure and monitor liquids.
Its compact design allows it to be used in equipment where only small space is
available. The large number of evaluating electronics offered means that the
system is suited for a wide range of applications.
The medium flows through a specially shaped flow housing and causes a vane to
rotate. This rotary motion is sensed by optoelectronics in a non-contacting
manner, and converted to an asymmetric frequency signal or an analogue signal.
A frequency divider with symmetrical output is available as an option. The
frequency is proportional to the flow velocity. The vane has a sapphire-bearing
and ensures a high degree of linearity and long service life.
6. Mechanical Connection
6.1. Check of operating conditions
 flow rate
 maximum operating pressure
 maximum operating temperature
Note! Exceeding the measuring range can cause damage to the axle
bearings, resulting in significant errors in measurement.
6.2. Mounting
 Flow in direction of the arrow (universal positioning).
 Avoid high pressure or tensile/torsion loads on the connection joints.
Fasten inlet and outlet pipe mechanically at a distance of approx. 50 mm from
the connection joint.
 Check the connections for leaks.
 We recommend a minimum inlet straight run of 5xDN and a minimum outlet
straight run of 2xDN.

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 before making any
connections.
Attention! Incorrect wiring will lead to damage of the unit’s
electronics.

9. Maintenance
As long as the measured medium is clean, the instrument is maintenance-free. In
order to avoid problems, we recommend the installation of a filter, e.g. the
magnetic filter, model MFR.
If cleaning of the sensor is necessary, the sensor can be opened, so that the
inner parts are accessible. Take care that the sensor and especially the vane are
not damaged; make sure that the mounting position and the mounting direction of
the vane is correct. All work on the sensor electronics should be done only by the
manufacturer; otherwise, the guarantee will become invalid.
