2. Note
Please read and take note of these operating instructions before unpacking and
putting the unit in operation, and 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 with the prevailing regulation applying to
procedural safety and the prevention of accidents.
When used in machines, the measuring unit should be used only then when the
machines fulfil the EC-machine guide lines.
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
These devices are checked before dispatch and shipped in perfect condition.
Should damage to a device be visible, we recommend a thorough inspection of
the delivery packaging. In case of signs of damage to the packaging, please
inform your parcel service/forwarding agent immediately, since they are
responsible for damages during transit.
Scope of delivery:
 Low Volume Rotating Vane Flow Meter model: DPM

4. Regulation Use
Any use of the Rotating Vane Flow Meter, model DPM, which exceeds the
manufacturers 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 Principles
KOBOLD model DPM flow meters are used for measuring and monitoring liquids.
Due to its compact construction the measuring instrument is suitable for use with
machines with minimum available space. The system can be used in a wide
variety of applications because the output pulses can be analysed in many
different ways.
The medium flows though a specially shaped housing nozzle and causes a vane
to rotate. This rotary motion is sensed by optoelectronics in a non-contacting
manner, and converted to a pulse frequency signal or an analogue signal. A
frequency divider with pulse output is available as an option. The frequency is
proportional to the flow velocity. The vane is sapphire-supported, this ensures a
high degree of linearity and long service life.

6. Mechanical Connection
6.1. Check service conditions:
 flow
 max. operating pressures
 max. service temperature
Attention! Overrange can cause damage to bearings and major
measuring errors
6.2. Installation
 flow in direction of arrow (universal)
 avoid pressure and tensile loads, mechanically fix inlet and outlet lines at
distances of 50 mm from the connections
 check connections for leaks

7. Electrical Connection
7.1. General
Attention! Make sure that the voltages in your plant correspond with
the flow meter voltages.
 Make sure that the electrical supply lines are dead.
 We recommend a power supply cable with cross sectional area of 0.25 mm².
Attention! The instrument electronics may be damaged if the cable
connections are wired incorrectly.

9. Maintenance
The measuring instrument requires no maintenance if the measured medium is
clean. To prevent coating the sensor optics, we recommend that a filter is
installed, for example the magnetic filter, model MFR.
If the sensor has to be cleaned, then it can be opened to gain access to the
inside parts. Make sure that the sensor and especially the blades are not
damaged. When re-assembling, make sure that the vane is positioned and
oriented correctly.
Work on the sensor and electronics should only be carried out by the supplier,
otherwise the guarantee is nullified.
