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.

7.5. Cable outlet with M12x1 angle plug electronic options F3x
and L3x
When using a pre-assembled M12x1 connection cable with angled plug, the
cable outlet is always aligned opposite to the flow direction.

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.

Batteries
Batteries containing pollutants are marked with a sign consisting of a crossed-out
garbage can and the chemical symbol (Cd, Hg, Li or Pb) of the heavy metal that
is decisive for the classification as containing pollutants:
Cd1 Hg2 Pb3 Li4
1. „Cd" stands for cadmium
2. „Hg" stands for mercury
3. „Pb" stands for lead
4. „Li" stands for lithium
