2.2 Use in accordance with the requirements
The measurement device type NivuSonic CO including respective sensors is in-
tended to be used for continuous flow measurement in slightly polluted to clear,
clean water or equivalent media in full pipes. Here the allowed maximum values,
as specified in chapter 2.3 must be strictly kept. All cases which vary from these
conditions and are not passed by NIVUS GmbH in writing are left at owner’s risk.
The device is exclusively intended to be used for purposes as described
above.
Modifying or using the devices for other purposes without the written consent
of the manufacturer will not be considered as use in accordance with the re-
quirements.
Damages resulting from this are left at user’s risk.
The device is designed for a lifetime of approx. 10 years. After that period an
inspection in addition with a general overhaul has to be made.
For installation and initial start-up the conformity certificates and test certifi-
cates of the respective authorities must be followed.
The transmitter and the sensors always have to be installed outside of Ex-

3.3 Installation of Spare Parts and Parts subject to wear and tear
We herewith particularly emphasize that replacement parts or accessories,
which are not supplied by us, are not certified by us, too. Hence, the installation
and/or the use of such products may possibly be detrimental to the device’s abil-
ity to work.
Damages caused by using non-original parts and non-original accessories are
left at user’s risk.
3.4 Turn-off procedure
For maintenance, cleaning and repairs (authorised staff personnel only) the
device shall be disconnected from mains and shall be prevented from being
turned on again unintentionally.
3.5 User’s Responsibilities
In the EEA (European Economic Area) national implementation of the frame-
work directive 89/391/EEC and corresponding individual directives, in particu-
lar the directive 89/655/EEC concerning the minimum safety and health re-
quirements for the use of work equipment by workers at work, as amended,
are to be observed and adhered to.
In Germany the Industrial Safety Ordinance of October 2002 must be ob-
served.
The customer must (where necessary) obtain any local operating permits re-
quired and observe the provisions contained therein.
In addition to this, he must observe local laws and regulations on
- personnel safety (accident prevention regulations)
- safety of work materials and tools (safety equipment and maintenance)
- disposal of products (laws on wastes)
- disposal of materials (laws on wastes)
- cleaning (cleansing agents and disposal)
- environmental protection
- approvals available from local authorities
Connections:
Before operating the device the user has to ensure, that the local regulations
(e.g. for operation in channels) on installation and initial start-up are taken into
account, if this is both carried out by the user.

4 Functional Principle
4.1 General
NivuSonic CO is a non-contact, stationary measurement system for flow meas-
urement and hence is pressure-independent. The storage of detected readings
and remote access using TCP/IP is carried out via network connection, Intranet
or Internet. It is mainly designed for use in slightly polluted to clear watery fluids
of various consistencies. It can exclusively be operated in full filled channels and
pipes.
The flow velocity measurement method is based on the ultrasonic transit time
principle. Due to this reason it is indispensable for the system functionality that
the solid content (dirt particles, gas bubbles or similar) is not too high to en-
able ultrasonic signal transmission between both sensors due to reflections
and hence damping.
The NivuSonic CO uses up to two sensor pairs for flow velocity determination.

4.2 Flow velocity detection
The flow velocity is determined by using the ultrasonic transit time principle.
1 Sensor 1
2 Sensor 2
Fig. 4-2 One-path transit time measurement principle
This measurement principle is based on directly measuring the transit time of
acoustic signals between two ultrasonic sensors, the so-called hydro-acoustic
converters.
A short ultrasonic impulse with a defined frequency sent towards the medium
flow direction in a defined angle requires a longer transit time than another im-
pulse being sent with the medium flow direction in an inverse angle.
The difference between the transit times is proportional to the average flow ve-
locity within the measurement path.
Flow determination is possible as soon as both cross-sectional area as well as
flow geometry of pipe or channel are known.
Presuming that C>> υ

and the flow direction is known, it is possible to ap-
proach the transit time (∆t) applying

Whereat:

C velocity of sound in water
υ

average flow velocity between sensors 1 and 2 along the measure-
ment path
Using two paths (instead of one as used for transit time measurement) fixed on
the outside of the pipe allows to collect more information on flow velocity and
flow can therefore be determined more accurate.

6 Installation
6.1 General
Regarding electric installation the local regulations in the respective countries
(e.g. VDE 0100 in Germany) must be referred to.
The NivuSonic CO power supply must be separately protected by a 6 A slow-
blow fuse and has to be isolated from other facility parts (separate turn-off,
e.g. by using an automatic cut-out with >B< characteristics).
Before feeding the rated voltage the transmitter and sensor installation must be
correctly completed. The installation should be carried out by qualified personnel
only. Further statutory standards, regulations and technical rulings have to be
taken into account.
All outer circuits, wires and lines connected to the device must have a minimum
isolation resistance of 250 V. If the voltage exceeds 42 V DC an isolation resis-
tance with 500 kOhm min. is necessary.
The section dimension of the power supply wires must be 0.75 mm2(0.03 in2)
and must be in accordance to IEC 227 or IEC 245. The unit protection rating is
IP 65.
The maximum switching voltage on the relay contacts must not exceed 250V.
According to Ex-protection it must be checked if the devices power supplies
must be integrated into the facility’s emergency shutdown conception.
6.2 Transmitter installation and connection
6.2.1 General
The transmitter mounting place has to be selected according to certain criteria.
Please strictly avoid:
- direct sunlight (use weatherproof cover if necessary, e.g. NIVUS weather-
proof cover Art. No. ZMS0 180000)
- heat emitting objects (max. ambient temperature: +50 °C)
- objects with strong electromagnetic fields (e.g. frequency converters, con-
tactors / relays, electric motors with high rated input or similar)
- corrosive chemicals or gas
- mechanical shocks
- direct installation close to footpaths or travel ways
- vibration
- radioactive radiation
For fastening the wall mount enclosure, depending on place of mounting, use 4
machine screws size M5 in suitable length as well as the necessary nuts and
shims. Or use 4 wood screws with min. diameter 4.5 mm. These screws must
reach min. 40 mm into the wall or min. 50 mm into appropriate dowels (to be
set).

®Instruction manual
NivuSonic Clamp on
The transparent door of the measurement transmitter is equipped with a protec-
tive foil for protection during transport and from scratches during assembly. This
protective foil has to be removed immediately after assembly.
If the view door with protection foil is exposed to direct sunlight for a long time,
the foil cannot be easily removed.
Cleaning of the front foil can be undertaken with spirit or if necessary with car
polish. If this is not successful, a new front door can be ordered from NIVUS
GmbH or your local representative
Never change the cable lengths of the sensors delivered since this will lead to
faulty measurements or even complete measurement failures.
