2. Note
Please read these operating instructions before unpacking and putting the unit into operation. Follow the instructions precisely as described herein. The devices are only to be used, maintained and serviced by persons familiar with these operating instructions and with the prevailing regulation applying to 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. Table 8, Pipe, Group 2 dangerous fluids
3. Instrument Inspection
These devices are checked before shipping and sent out in perfect condition. Should damage to a device be visible, we recommend a thorough inspection of the delivery packing. In case of damage, please inform your parcel service/ forwarding agent immediately, since they are responsible for damages during transit.
Scope of delivery:
Turbine-wheel Flow Meter, Model: DRB Operating Instructions
4. Regulation Use
The “turbine-wheel flow meter, model DRB“, is to be installed only in specified applications. Any usage which exceeds the specifications is considered to be no­specified, and would also invalidate the warranty. Any damages resulting therefrom are not the responsibility of the manufacturer. The user assumes all risk for such usage. The application specifications include the installation, start-up and service requirements specified by the manufacturer.

5. Operating Principle
The KOBOLD flow meter model DRB is used for measuring and monitoring liquids. The device works according the well-known paddle wheel principle. The four vane paddle wheel is retained radially in a high quality sapphire bearing. The sensor is supplied ready-to-install with pipe fittings or with weld-on sleeves. The paddle wheel is set in motion by the flowing medium. Magnets are embedded hermetically sealed in the ends of the blades. The magnets generate electrical pulses in a Hall-effect sensor mounted outside the flow area. Various electronics units can be used to display and monitor the volumetric flow.
6. Mechanical Connection
6.1. Examine operating conditions:
Flow volume Max. operating pressure Max. operating temperature
Ensure that they are all within the limits of the device
Attention! Over-ranging may cause bearing damage and considerable measurement errors.
6.2. Installation
Flow in the direction of the pointing arrow (position independent) Pressure and tensile loading should be avoided The inlet and outlet should be secured at a distance of 50 mm mechanically
from the connection.
Check the sealing of connections/joints

Version with weld-on mounting adapter
Weld the mounting adapter in the piping according to the sketch given below.
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
Attention! Make sure that the power supply voltage corresponds with the voltage requirement of the flow meter.
Ensure that power supply is de-energized Connect the power supply and the output signal to the plug-pins, as shown
below.
We recommend a cross-section of 0.25 mm² for the power supply cable.
Attention! Incorrect wiring may cause permanent damage to the sensor.

8.1. General
The Measuring units factory are pre-set and are ready for use after electrical connections are made.
8.2. Adjustment – Compact electronics

8.3. Adjustment – ADI display/controller
see Instruction Manual-Supplement for ADI-series display/controller
9. Maintenance
The measuring unit is maintenance-free if the medium to be measured does not cause deposition of impurities. In order to avoid problems, we recommend installation of a filter, such as magnet filter, model MFR. Should cleaning of the sensor becomes inevitable, after opening the sensor the inner parts may be accessed. Note the direction that the turbine points during removal and re-install in the same direction. Please be careful to avoid any damage to the sensor and in particular, to the turbine blades. Repair work regarding electronics may only be carried out by the supplier. Any access or work on the electronics voids the warranty.
