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.

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:
Pulse generator model: OM…/43/44/45
4. Regulation Use
Any use of the device, 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.
Only use the Kobold pulse generator within the operating limits specified in the
"Technical Data" chapter. Deviating operating data can lead to damage. If in doubt,
consult the manufacturer.
5. Operating Principle
The rotor of the screw-type volumetric flow meter rotates at a precisely defined
distance in front of the pulse generator. The pulse generator generates a pulse for
every pole that moves past it.
The screw-type volumetric flow meter is checked and delivered with a built-in dry
sleeve. The transmitter insert for the pulse generator can be replaced online in a
full line, without having to re-adjust the clearance to the rotor.

6. Safety Information
The following safety instructions must be observed:
Implement all the supply lines without faults.
The pick up system (puck up, transducer and lines) may not be located in
the area of strong, high-frequency electromagnetic fields, such as those
emitted e.g. from power lines, electric motors, frequency converters, etc.
This can result in erroneous measurements of the pick up system.
In case of systems with an increased potential of danger to humans and/or
machines the failure of a pick up may not lead to injuries or damage to
property.
• Always equip systems with an increased potential of danger with
alarm equipment.
• Maintain and check the protective/alarm equipment regularly.
The pumped liquids can be dangerous (e.g. hot, dangerous to health,
poisonous, combustible). Observe the safety conditions for handling
dangerous materials.
Pumped liquids can be subject to pressure and can cause damage and/or
personal injury should leaks occur.
Depending on operating conditions, the service life of the pick ups is limited
due to vibrations, temperature influences or deterioration. The operator-
owner is responsible for regular inspection.
• All parts which jeopardize safe operation must be replaced regularly.
• Abnormal operating mode or visible damage prohibits further use.

8. Assembly and Disassembly
The pick up system (puck up, transducer and lines) may not be located in the area
of strong, high-frequency electromagnetic fields. This can result in erroneous
measurements of the pick up system.
The connecting lines of the pick up connections are to be shielded and laid
separately from the supply lines.
Ensure that the supply voltage is correct.
Installing the pick up
By default, flowmeters are supplied with a premounted pick up or premounted dry
sleeve respectively.
Be sure to observe the following instruction:
When replacing the pick up insert it is not necessary to change the position of the
dry sleeve. Damage to the red sealing point shows that the dry sleeve has been
repositioned. In this case the guarantee for the flowmeter becomes null and void.
Replacing OM…/43
Removing OM…/43
1. Loosen the knurled nut of the pick up plug 493 and pull out the plug.
2. Loosen the hexagon nut 626.3, spacer 626.2 and sleeve 626.4.
3. Pull out the pick up insert 624.1 with spring 624.2.
4. Turn out the pressure housing 626.1.

Installation position
1. Clean the pick up hole. At flowmeters of the OMG and OMH series check
the inserted O-ring.
2. Screw the pressure housing 626.1 into the pick up hole up to a distance of
0.5 mm (43D) respectively 1.0 mm (46D) from the outer diameter of the pole
wheel. (One rotation corresponds to 1 mm.)
3. Lock with the spacer 626.2 and hexagon nut 626.3.
4. Slide the pick up insert 624.1 and spring 624.2 into the pressure housing
626.1. Fasten with sleeve 626.4.
5. Connect the pick up plug 493. Observe the terminal diagram.

Removing OM…/44
1. Separate the pick up cable from the supply voltage.
2. Loosen threaded cover 624.3. Pull the pick up insert 624.1 and spring 624.2
out of the pressure housing 626.1.
3. Loosen the hexagon nut 626.3 and spacer 626.2.
4. Turn out the pressure housing 626.1 with indexing sleeve 626.5.

Installation position
Replacing OM…/44
1. Clean the pick up hole. At flowmeters of the OMG and OMH series check
the inserted O-ring.
2. Screw the pressure housing 626.1 into the pick up hole up to a distance of
0.25 mm from the outer diameter of the pole wheel. (One rotation
corresponds to 1 mm.)
3. Lock with the spacer 626.2 and hexagon nut 626.3.
4. Position the flowmeter see Fig. Position flowmeter at pick up installation
5. Press the indexing sleeve 626.5 while making sure that the position is
correct, see Fig. Position flowmeter at pick up installation
The correct position of the groove is rotated by 90° to the left in the flow
direction, max. angle error+/- 10°.
6. Slide in the pick up insert 624.1 and spring 624.2 while ensuring that the
sleeve is clean and the position of the positioning pin A is correct. This must
be latched in the groove of the indexing sleeve 626.5, see Fig. Positioning
pin latching in. Screw tight the threaded cover 624.3. Connect the pick up.
Observe the terminal diagram, see Fig. Terminal diagram
