3. Instrument Inspection
All 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:
 Turbine-wheel Flow Meter model: DPE-...

4. Regulation Use
Any use of the Turbine-Wheel Flow Meter, model: DPE-..., 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 Principles
The Kobold flow meter model DPE is used for measuring and monitoring liquids.
The device works according the well-known blade wheel principle. The six vane
blade wheel is retained axially in a high-quality sapphire bearing. The sensor is
supplied ready-to-install with pipe fittings or with weld-on sleeves.
The blade wheel is set in motion by the flowing medium. Hermetically sealed
magnets are embedded in the ends of the blade wheels. The magnets generate
electrical pulses in a Hall-effect sensor mounted outside the flow area.
6. Mechanical Connection
6.1. Check the installation conditions:
 Flow volume
 Max. operating pressures
 Max. operating temperature
Caution! Exceeding the measuring range will damage the bearings
in the device and lead to significant errors in measurement.

Standard installation
 Ensure that the flow is in the direction of the arrow (universal positioning).
 Avoid pressure and tension loads on the device.
Mechanically secure the inlet and outlet lines at a distance of 50 mm from the
connections.
 Check the connections for leaks.
Installation with mounting adapter:
(DPE-1200W...)
Weld the adapter to the piping (to the proper depth, using H reference) as shown
in the drawing (flow is in direction of arrow).

Position and weld-in the mounting adapter according to the nominal diameter
suitable marking. The marking on the adapter must be in line with the outer
diameter of the pipe. Also pay attention to the later position of the rotating vane
(shaft of the vane shifted by 90° to the direction of flow).

7. Electrical Connection
7.1. General information
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-energized.
 Connect and plug in the system according to the connecting plans.
 We recommend to use wires with cross sectional area of min. 0,25 mm²
Attention! Wrong wiring will lead into damage of the unit’s electronic.
