WARNING

Seal unused connection sockets

Unused connection sockets on the Type EBM Electronic Box shall be sealed
watertight by using the screw cover fastened on each socket prior to installa­tion. Otherwise the protection grade of the entire unit is no longer guaranteed.
Damages resulting due to not using the covers are not covered by the manu­facturer’s liability.
Covers being damaged or lost due to the use of force can be ordered from
NIVUS at extra costs.

Keep threads of plugs and sockets carefully free of dirt, sand or similar and
clean the threads with a soft and lint-free cloth prior to connection if required.

If placed in flood shafts or channels the transmitter must be secured in order
to prevent it from being washed away unintentionally (use suspension gear,
plastic or steel rope, chain or similar).

®

In case of using other manufacturer’s transmitters the operator is obliged to
implement a system ass es s ment accor d ing to EN 60079-25.

The required specifications for Ex-version sensors can be taken from the
EC-type examination certificate TÜV 03 ATEX 2262 or TÜV 12 ATEX 087812

WARNING

When connecting the sensor to the transmitter the metal sensor ground plate
must not exceed 1 GΩ grounding resistance!

In this case make sure to eliminate the risk of explosive atmospheres by us­ing a gas warning unit prior to installation or maintenance works. Please ob­serve to avoid building up electrostatic energy during the works!

CSM Sensor

The sensor type CSM is designed for flow velocity measurement of slight to
heavily polluted media in part filled or full pipes and channels with low levels.
The CSM sensor can be operated exclusively in connection with the accompa­nying Electronic Box EBM. For Type CSM-V100 an addition al le vel m eas ur e­ment is required.

DSM Sensor

The sensor type DSM is designed to measure level of liquid media using ultra­sound from top down in pipes featuring small dimensions. The sensor can be
operated exclusively in con nectio n w ith the acc ompanying Electronic Box EBM.

EBM Electronic Box

The Electronic Box Type EBM is conceived to connect the sensors Type CSM
and DSM. It contains the detached electronic sensor components and is de­signed to be connected to Type PCM Pro / 4 or OCM Pro transmitters.

POA Sensor

The sensor type POA is designed to measure flow of slight to heavy polluted
media in part filled and full sewers, pipes and other channels. Level measure­ment is additionally possible depending on the sensor type.

OCL-L1 Sensor

The sensor type OCL-L1 is designed to measure level of liquid media using ul­trasound from top down.

CS2 Sensor

The sensor type CS2 is designed for flow velocity measurement of slight to
heavily polluted media in part filled or full pipes and channels and featuring large
dimensions and a minimum filling level of 10 cm. Level measurement is addi­tionally possible depending on the sensor type.

Please necessarily observe the maximum permissible limit values as specif ied in
chapter 4. Any cases varying from these conditions without written consent of
NIVUS GmbH are entirely left at owner’s risk.

5.7 Cable extension

WARNING

WARNING

Electrical connection

Cable extension and sensor connection should be accomplished by author­ised expert staff only.

Possible electrical interf e rence

If you wish to extend cables by using a terminal box use a box made of metal.
The shields of outgoing as well as incoming cables must be wired to the
ground connection of the terminal box.

Inappropriate connections leading to increased contac t resis tance or the us e
of unsuitable cables may result in interferences or even measurement fail­ures.

Sensors with integrated pre s sure cell and sensor connection type „L“ (see Fig.
2-12) are equipped with a specially prepared cable type LIY11Y 2x1.5 mm² +
1x2x0.34 mm² + PA 1,5/2,5. Sensors without pressure measur em ent cell as well
as the external Electronic Box with sensor connection type "K" are equipped with
cables type LIY11Y 2x1.5 mm² + 1x2x0.34 mm². These cables can be extended
without any problem by using single shielded signal cables.
Sensors with integrated pressure cell and sensor connection types "F" or "S"
are equipped with the respectiv ely wired plugs; type „F“ are equipped with an
additional air filter with a dehydration agent on the connection plug (see Fig.
5-26). These sensors cannot be extended.

Technical Instructions for

Correlation Sensors

Correlation Sensors – Rev. 07 as of 20.04.2016 Page 49

The signal cable fixed on the sensor is not designed to be laid in the ground
permanently. If you wish to lay signal cables into soils, concrete or similar please
use additional protective pipes or hoses with sufficient inner diameters. Please
select inner diameter, bending radius and layout of protective pipes and hoses in
a way which enables to remove old signal cables and to draw in new ones with­out any problems.

When extending the sensors please note that the allowed total resistance of
the power supply lines must not exceed at

- sensors with 10 m (30 ft) fixed cable: 2.100 Ohm

- sensors with 20 m (60 ft) fixed cable: 1.850 Ohm

- sensors with 30 m (90 ft) fixed cable: 1.600 Ohm

(feed + return wires!).

(In special cases even higher cable lengths may be possible taking special
cross-sectional cable areas into account. Please request more information on
these particular cases from NIVUS).
If an application requires the use of 2 or 3 flow velocity sensors, it is possible to
extend the sensor cables using one common signal cable.

It is not allowed to use common extensions in case of different applications or
to use a common signal cable to extend separate level and flow velocity
measurements.

The maximum cable length for air-ultrasonic sensors type OCL is 100 m
(328 ft). This sensor cable shall not be extended.

NIVUS recommend cable type A2Y(L)Y 6x2x0.8 (or more wires) for extension
purposes. Two wires are required for bus communication. Connect remaining
wires in parallel in a way to obtain 2 lines for power supply (same number of
wires for each line).

The maximum permissible length of the fixed cable between flow velocity sensor
and transmitter is 150 m.
The maximum cable length may be extended to up to 250 m as follows: use
sensors with 30 m (98.4 ft) fixed cable and extend the cable by using a connec­tion box together with an extension cable with a larger c ros s -section than the
fixed cable.
It is possible to use cables of other types with a minimum cable cross-section of

0.8 mm² and a common shield. Please contact NIVUS if in doubt regarding ap­propriate cable types.

In case of using type A2Y(L) 2Y as mentioned above, the extension of both sig­nal lines (RxTx) is made with one wire each.
The power supply UE and earth UE-GND extension is carried out with one or
more parallel connected wires per line depending on the distance.
The number listed below is the minimum per connection!

5.8 Pressure compensation element for CSM Sensors

WARNING

Ingress of moisture

of wires for extension
(no reserves)

Never operate sensors with integrated pressure cell without or with used dry­ing capsules.

Moisture leaking into the cell will irreversibly damage the built-in electronic
components of the sensor!

The drying capsules avoid ingress of moisture!
Please regularly check and replace the drying capsules if required.

The pressure compensation element for CSM sensors is equipped with 2 drying
capsules. These capsules prevent moisture from leaking in and preserve elec­tronic components. The drying capsules shall be checked and replaced if re­quired regularly (depending on the ambient conditions).

Please observe the maintenance hints in chapter 7.3!

5.9 Pressure compensation element for POA- and CS2- sensors

WARNING

Penetration of moisture

Operating sensors with integrated pressure measurement cell without pres­sure compensation element for a longer period of time may lead to irreversi­ble damage of sensor electronics.

Use NIVUS pressure compensation elements exclusively to operate sensors
with integrated pressure cell.
Sensors with integrated pressure measurement cell and sensor connection
types „F“ or „S“ have a configured plug, type „F“ additionally have a preconfig­ured filter element, which works as a pressure compensation element (see Fig.
5-26). This sensor cables shall not be extended.

For sensors with pressure measurement cell (types V1D, V2D, V1U, V2U see
Fig. 2-12) the maximum uninterrupted cable length is 30 m (90 ft). For cable ex­tension a connection box with pressure compensation (pressure compensation
element) has to be installed.
This pressure compensation element has to be installed even if the cable of a
sensor with integrated pressure measurement cell is connected directly to the
OCM Pro transmitter.
It is available directly from NIVUS under order article no. >ZUB0 ZDAE<.

6 Table of Resistiveness

Correlation Sensors

WARNING

Damage due to aggressive media

As a basic principle, damage might occur in case of using chloride media (pit­ting corrosion in stainless steel ground plate or sensor jacket), hydrogen sul-

destruction of copper wires and conductor paths) as well as various organic

phide (H

S – risk of diffusion through cable sheath or sensor body resulting in

2

solvents (may dissolve cable sheath or sensor body)!
Sensors and cables shall be installed exclusively in media according to the

table of resistiveness below.
Sensor installation and cable layout sha ll be exec ute d ex clus ively in media

according to the table of resistiveness below! Otherwise the measurement sys­tem may be damaged irreversibly.

The medium contacting parts of the sensors consist of:

- V4A (ground plate or pipe sensor jacket)

- PPO GF30 (sensor body)

- PEEK (sensor crystal cover)

- Polyurethane (cable sheath and glands)

- PTFE (gasket of sensor screw joint)

- PA GF30 (protective cover for wedge sensor type CS2)

The following materials are used additionally for sensors with pressure
measurement cell:

- Has tel loy® C-276

- Viton® (PA/PR)

The sensor technology is resistant to normal domestic sewages, dirt and rain
water as well as mixed water from municipalities and communities. Also in many
industrial plants (e.g. Huels, BASF etc.) the resistance does not present any
problems. The sensor technology nevertheless is not resistant to all substances
and substance mixtures.

Please observe that substance mixtures (several substances being present sim­ultaneously) under certain circumstanc es ma y cause catalytic effects which
might not occur if the individual substances are in use. Due to infinitely possible
combinations these catalytic effects cannot be verified entirely.
If in doubt please contact your NIVUS representative and request a free material
sample for long time testing purposes.

For use in special applications with high aggressive or solvent-containing media
there are sensors made of full PEEK available with ground plates made of Has­telloy or Titanium as well as pipe sensors made of high resistant special steel.
Sensor cables which have to be immersed into the medium are available with a
special FEP coating (resistant to organic solvents or hydrogen sulphide).

7 Maintenance and Cleaning

WARNING

WARNING

Germ contamination

Due to using the sensors mostly in the waste water field which may be con­taminated with hazardous germs, please ensure to take respective precau­tions getting in contact with system, transmitter, cables and sensors.

In heavily polluted media tending to sedimentation it may be necessary to clean
the flow velocity sensor regularly. To do so, please use a brush with plastic bris­tles, a broom or similar.

Polluted plugs (sensor connection F or S) and sockets must be cleaned and
dried before reconnect a sensor. Remove touch dry dirt with compressed air or
by using a brush with plastic bristles (no metal!). If required, maintain the con­tacts by using a contact spray.

Damage by hard objects

No hard objects such as wire brushes, rods, scrapers or similar shall be used
to clean the sensor. Cleaning by using a water jet is allowed up to a max. pres­sure of 4 bar (see Specifications) (e.g. using a water hose). Never clean flow
velocity sensors with pressure measurement cell (types V2D and V2U) by us­ing a water jet!

Using a high pressure cleaner may damage the sensor resulting in measure­ment failure and is therefore absolutely not allowed.

7.1 Water-US Combi Sensor with Pressure Measurement

WARNING

WARNING

Do not remove parts

Removing or loosening of the ground plate or cable gland results in leakage
and therefore will cause measurement and sensor failure.

Only the cover of the pressure measurement is allowed to be removed. Do
absolutely not remove other parts of the sensor!!

Damage of pressure measurement cell during cleaning

Never clean the pressure cell using a water jet, screw driver or similar!
It is not permitted to touch the probe with the fingers or other objects
(see Fig. 7-1)

This will irreversibly damage the pressure cell!
It is allowed to clean the pressure measurement by using slight flushing

movements in a vessel filled with water.
Bei Verletzung dieses Verbotes erlischt die Gewährleistung seitens des Her-

stellers! If in doubt please let NIVUS do the cleaning

Technical Instructions for

Correlation Sensors

Page 60 Correlation Sensors – Rev. 07 as of 20.04.2016

®

If the measurement medium contains substances (e.g. grease, lime) which may
sediment on the pressure opening, they must be removed in order to prevent
measurement faults.
The duct to the pressure measurement which is milled into the ground plate
must be flushed with water imm ediately after each de-installation to avoid sedi­mentation. To do this, immerse the probe into water several times.
The cover on the pressure measurement can be removed for more extensive
cleaning purposes.
The opened pressure cell must be cleaned very carefully. Slightly move the
pressure probe in a container filled with water (e.g. bucket) to flush. Stric tly avoid
touching the probe with fingers, brushes, tools, water jets and similar! Disregard­ing invalidates the manufacturer warranty!

Important Note:

If sedimentation which cannot be removed prevents correct measurement the
sensor must be maintained by NIVUS.

1 Pressure sensor

Fig. 7-1 Wedge sensor with pressure measurement cell, bottom view

Due to physical reasons, level measurements performed by sensors with pres­sure measurement cell are subject to long-term drift (see chap. 5.9). NIVUS
therefore recommend to calibrate sensors with integrated pressure measure­ment cell twice a year regarding the respective zero point. The best results are
going to be achieved if the water level is as low as possible or if the sensor has
been removed from the measurement medium. The calibration procedure is de­scribed in according Instruction Manuals of OCM Pro or PCM transmitters.

The combination sensors with pressure measurement cell ar e equi ppe d with an
additional air filter with a dehydration agent on the connection plug. This dehy­dration agent is subject to normal wear which depends on measurement dura­tion, measurement interval, air pressure fluctuation and environmental condi­tions. The filter wear is indicated by the dehydration agent turning from dark blue
to pale violet.
The air filter has to be controlled each time before use, replacing the battery or
reading out data. If the colour is beginning to change the air filter must be re­placed by a new one of the same type.
Spare filters are available from NIVUS under Art. No. ZUB0 FILTER02 (also see
chapter 0).

7.2 Air-Ultrasonic Sensor

These sensors are normally non-contacting. Hence, it is necessary to check if
the transmitting pad is not covered and the sound beam is free to reach the wa­ter surface after immersion (flooding) into the measurement medium only.
In case of pollution clean the sensor with water and a cloth or a soft brush.

WARNING

Do not remove any parts

Except the ground plate2 (see Fig. 5-5 or Fig. 5-12)
no other parts are allowed to be removed from the air-ultrasonic sensor!

Removing or loosening of ground plate or cable glan d r esult in leaka ge and
therefore will cause measurement and sensor failure.

7.3 Pressure Compensation Element for CSM Sensors

When using CSM sensors with pressure measurement cell and pressure com­pensation element the built-in drying capsules (see Fig. 5-27) need to be regu­larly checked and replaced if required. Inspection intervals depend on the pre­vailing air humidity and may vary betwee n 2 and 12 week s dependin g on appli­cation.

As soon as the drying capsules are used up their colour will change from orange
to white. The capsules then need to be replaced.

- O RANG E = new capsule / not yet used up

- WHITE = capsule used up – please replace both capsules

To replace the drying capsules unscrew the 4 crosshead screws on the acrylic
cover. Before inserting new capsules remove the protective aluminium foil.
Please observe to insert the capsules with the board side down.
The O-ring of the pressure compensation element (see Fig. 5-26, point 4) is for
sealing and must always remain in the groove.
Keep the O-ring free of dirt. When closing the acrylic cover avoid dirt, sand or
similar between the pressure compensation element and the cover. Otherwise
the tightness of the pressure compensation element can be affected.

on the bottom absolutely

When replacing the drying capsules please observe the glued O-ring to re­main in the groove. Necessarily keep the ring free of dirt since otherwise the
pressure compensation ele ment may leak .

Spare capsules are available from NIVUS (see chapter 9).

7.4 Pressure Compensation Element for POA and CS2 Sensor

Inspect the filter element regularly when mounting POA or CS2 sensors with
pressure measurement cell and pressure compensation element (see Fig. 5-28).
Inspection intervals depend on the prevailing air humidity and may vary between
2 and 12 weeks depending on application.
If the desiccant colour should change by more than 50 % replace the filter or the
desiccant. Both can be purchased from NIVUS (see chapter 0).
