I. Forword
Read these operating instructions carefully and completely before
installation, start-up and maintenance work. Follow the instructions to
ensure safe operation and proper functioning.
The operating instructions must always be available at the place of use. It
is not permitted to make only individual pages available.
Important notes for installation and maintenance personnel
Installation of the flow sensor is only permitted by trained skilled staff
with knowledge and experience in compressed air and electrical
engineering.
Electrical connection, commissioning and maintenance may only be
carried out by qualified electricians in accordance with the
electrotechnical regulations (DIN EN 50110-1, DIN EN 60204-1 etc.).
Prerequisite: Professional training and knowledge of the technical
standards, EU directives and EU regulations.
Observe applicable national accident prevention regulations and
ordinances. Observe general occupational health and safety
measures,
E.g. wear suitable and prescribed personal protective equipment
(PPE). Repairs and adjustments may only be carried out by the
manufacturer.
Duties of the installer and plant operator
The flow sensor must be checked and maintained regularly by an
instructed and qualified person.
Cleaning and maintenance intervals are to be determined by the plant
operator according to DIN-ISO certification - frequency depending on
ambient conditions and expected impairments.
Calibration: As part of DIN ISO certification, have the flow sensor
calibrated at regular intervals, after 2 years at the latest.
Remove the flow sensor for calibration and send it to CS Instruments
GmbH & Co.KG.

3 Intended Use
The VX 570 flow sensor is used for continuous flow measurement, based on the measurement of the
vortex shedding frequency, derived from the phenomenon of Karman's vortex street.
The VX 570 flow sensor is designed and constructed exclusively for the intended use described here
and may only be used accordingly.
A check as to whether the device is suitable for the selected application must be carried out by the
user. It must be ensured that the medium is compatible with the wetted parts. The technical data listed
in the data sheet are binding.
Improper handling or operation outside the technical specifications is not permitted. Claims of any
kind due to improper use are excluded

Ensure that the flow sensor is only operated within the permissible limit values (→
type plate, specified max. PS pressure) and that the measuring range end values
are taken into account.
Risk of injury due to unauthorized device modifications, incorrect
installation or damaged components. The operating permit becomes
invalid in these cases. Operation is only permitted with original
components.
Only operate the flow sensor when it is completely assembled. Do not operate a
damaged sensor and prevent further use until it has been repaired. The sensor
must be checked and maintained regularly by instructed and qualified persons.
Device modifications are not permitted and release the manufacturer from any
warranty and liability.
Explosion risk in Ex-protected areas due to ignition of explosive
substances when sparks are generated. The flow sensor does not have
Ex approval! Do not use the flow sensor in Ex-protected areas.
4.4 Environmental protection
The flow sensor and also the packaging contain recyclable materials
which must not be disposed of in the residual waste. Dispose of the
packaging materials and the flow sensor in an environmentally friendly
manner at the end of its service life in accordance with the regulations
applicable in your country.
The used operating and auxiliary materials as well as replacement parts
produced during operation of the flow sensor must be disposed of in
accordance with the environmental protection regulations.
DE: Disposal code according to Waste Catalogue Ordinance (AVV) 16
02 14, electrical and electronic devices and their components.

7 Installation
7.1 General notes for the Installation
Information!
Check the packaging carefully for damage. In case of damage, please contact the carrier or CS
Instruments GmbH & Co.KG.
Information!
Check the completeness of the delivery.
7.2 Storage
•Store the sensor in a dry and dust-free place
•Store the sensor in the original packaging
•The permissible storage temperatures are -40°C ... 80°C
7.3 Transport
Attention!
•There is a risk of injury from unsecured devices.
During transport, prevent the device from slipping or turning
unintentionally.
•Do not use transport chains, as these will damage the housing.
•The unit must not be lifted by the housing head for transport.
•For transport, use carrying straps which you place around both process
connections.
7.4 Pipe/tube requirements
•Correctly sized gaskets
•Correct aligned flanges and gaskets
•Diameter mismatch at the pipe junctions should be avoided but must be less
than 1mm. For further information see ISO 14511
•Ensure clean pipes after installation

Measuring ranges
VX 570 English V1.10 Seite 15 von 44
7.5 Inlet / Outlet runs
In order to maintain the accuracy stipulated in the data sheets, the sensor must be inserted in the
center of a straight pip e section with an undisturbed flow progression.
An undisturbed flow progression is achieved if the sections in front of the sensor (inlet) and behind the
sensor (outlet) are sufficiently long, straight and without any obstructions such as edges, seams, curves
etc.
Therefore, it is necessary to ensure the recommended inlet and outlet runs.

be expected to get increased or significant deviations of the measurement values.
8 Commissioning
•Depressurize the system
•Ensure correct direction of flow during installation
•Maintain an undisturbed flow course while observing the required calming distances in
the measuring range, see section 7.5
