tions in the instruction manual. The requisite Health & Safety regulations for a given
application must also be observed. This statement also applies to the use of accessories.
Every person who is commissioned with the initiation or operation of this device must have
read and understood the operating instructions and in particular the safety instructions!
The work safety instructions in this manual as well as the safety, accident prevention and
environmental protection regulations generally valid for the work area must be observed.
The liability of the manufacturer expires in the event of damage due to improper use, non-
observance of this operating manual, use of insufficiently qualified personnel and unau-
thorized modification of the device.
Proper Usage
The flow meters DV04 are designed to monitor continuous flow rates of liquids which do
not attack the device materials. All other usage is regarded as being improper and outside
the scope of the device.
In particular, applications in which shock loads occur (for example, pulsed operation)
should be discussed and checked in advance with our technical staff.
The series DV04 flow meter devices should not be deployed as the sole agents to prevent
dangerous conditions occurring in plant or machinery. Machinery and plant need to be
designed in such a manner that faulty conditions and malfunctions do not arise that could
pose a safety risk for operators.
DV04 Instruction manual 02/2021 page 2

Dangerous substances
For dangerous media such as e.g. Oxygen, Acetylene, flammable or toxic substances as
well as refrigeration systems, compressors, etc. must comply with the relevant regulations
beyond the general rules.
Qualified Personnel
The DV04 devices may only be installed by trained, qualified personnel who are able to
mount the devices correctly. Qualified personnel are persons, who are familiar with
assembling, installation, placing in service and operating these devices and who are suit-
ably trained and qualified.
Inward Monitoring
Please check directly after delivery the device for any transport damages and deficiencies.
Additional with reference to the accompanying delivery note the number of parts must be
checked.
Claims for replacement or goods which relate to transport damage can only be considered
valid if the delivery company is notified without delay.
Functional principle and construction
Within the DV04 there two gearwheels that are supported in low-friction bearings. During
operation, the gearwheels are driven by the flowing liquid. The movement of the gear-
wheels is sensed by two non-contact sensors located in the cover and converted into elec-
trical signals.
Between the sensor area and the measuring chamber there is a pressure-resistant anti-
magnetic separator. The signals are transmitted to the connected display device.

Special Conditions
Special conditions and/or limitations apply to the safe application of gearwheel flow meters
in the approved operating environment. These conditions and/or limitations must be met
by the customer and/or system operator by means of appropriate technical and/or
organizational measures.
•Gearwheel flow meters must only be operated in the specified environment and
under the specified ambient conditions.
•Gearwheel flow meters must only be used if the materials used in their construction
are resistant to mechanical and/or chemical influences or corrosion under the given
service conditions.
•The fluid must at least have minimum lubricating properties (lubricity).
•Gearwheel flow meters are intended for use with liquids. Dry operation is not
approved.
•Operation outside of the specified parameters is not allowed.
•If necessary, a filter must be installed to prevent the gearwheel from being blocked
by foreign objects.
•The specified installation, service and maintenance schedules must be strictly fol -
lowed.
•Gearwheel flow meters must only be used in closed operation and not be subject to
excessive vibration.
•Only genuine spare parts must be used for service and maintenance.
Corrosion Protection
All gearwheel flow meters are checked for proper function at the factory with mineral-
based hydraulic oil. Following testing, the connections are sealed with plugs so that the
internal parts are protected against corrosion for a moderate amount of time.
During transport and storage, gearwheel flow meters must not be exposed to the harmful
effects of ambient weather conditions and great variations in temperature. They must be
stored under dry conditions.
If a gearwheel flow meter is to be stored for a longer period of time, both its interior and
exterior must be protected by application of a suitable anti-corrosion oil. In addition, it must
be protected from humidity by means of a desiccant material.
If high humidity or other unfavorable (aggressive, polluted) ambient conditions are expec -
ted to be encountered during transport, appropriate steps must be taken to prevent corro -
sion of the gearwheel flow meter.
Attention:
When preserving, check whether the preservative is compatible with the materials and
elastomers used in the gearwheel flow meter. Furthermore, compatibility with the pumped
medium must be ensured.

Description:
The measuring mechanism of the flow meter DV04 consists of
a pair of gears which are driven by the liquid flow according to
the operating principle of a gear pump.
The movement bearing is designed as plain bearing or ball
bearing. The movement of the gears is scanned by two
magnetoresistive sensors, which are hermetically separated
from the measuring chamber and phase-shifted by 0°.
This two-channel scanning enables a higher measured value
resolution as well as the detection of the flow direction by
means of suitable electronics. As an option, all devices are
available in explosion-proof design with separate switching
amplifier. The gearwheel flow meter DV04 is characterized by
very low flow resistance and particularly low sound pressure
level.
Typical applications:
Due to the outstanding measuring accuracy, combined with
the high resolution, these devices are particularly suitable for
use in test benches for measuring small and very small flow
rates.
Further fields of application:
• consumption measuring
• control of filling processes
• dosage of oils and chemicals
• flow measurement of paints and varnishes
• ratio control of polyol and isocyanate
