2.1 Intended use
CAUTION!
Responsibility for the use of the measuring devices with regard to suitability, intended use and
corrosion resistance of the used materials against the measured fluid lies solely with the
operator.
INFORMATION!
This device is a Group 1, Class A device as specified within CISPR11:2009. It is intended for use in
industrial environment. There may be potential difficulties in ensuring electromagnetic
compatibility in other environments, due to conducted as well as radiated disturbances.
INFORMATION!
The manufacturer is not liable for any damage resulting from improper use or use for other than
the intended purpose.
The vortex flowmeters are used for flow measurement of gases, vapours and liquids.
The devices are particularly suitable for the measurement of:
• Clean liquids with low viscosity (< 10 cP)
• Hydrocarbons with low viscosity (< 10 cP)
• Water
• Chemicals with low corrosiveness
• Saturated steam
• Superheated steam, including CIP and SIP applications in the food industry
OPTISWIRL 4200
®
• The flow sensors are made from stainless steel 316 L (1.4404) or Hastelloy
• In your project planning, please observe the data given in the corrosion tables.
• The pressure-bearing parts have been designed and rated for stationary operation taking into
account the maximum pressure and temperature.
• Observe the data indicated on the nameplate for PS, TS and PT (PED 97/23/EC).
• External forces and moments, caused e.g. by pipe stresses, have not been taken into account.
Primarily, volumetric flow and temperature are measured, with pressure measurement as an
option. From these parameters the measuring device calculates the mass flow or standard
volumetric flow using pre-programmed density data and then exports the measured values via
various communication interfaces.

INSTALLATION
2.5 Installation conditions
INFORMATION!
For accurate volumetric flow measurement the measuring device needs a completely filled pipe
and a fully developed flow profile.
CAUTION!
Any vibration will distort the measuring result. That is why any vibrations in the pipeline must be
prevented through suitable measures.
CAUTION!
Procedures to carry out before installing the device:
•
Nominal diameter of connection pipe flange = nominal flange diameter of pipe!
•
Use flanges with smooth holes, e.g. welding neck flanges.
•
Align carefully the holes of the connecting flange and the flowmeter flange.
•
Check the compatibility of the gasket material with the process product.
•
Make sure that the gaskets are arranged concentrically. The flange gaskets must not project
into the pipe cross-section.
•
The flanges have to be concentric.
•
There must not be any pipe bends, valves, flaps or other internals in the immediate inlet run.
•
Devices in sandwich version may only be installed using centering rings.
•
Never install the device directly behind piston compressors or rotary piston meters.
•
Do not lay signal cables directly next to cables for the power supply.
OPTISWIRL 4200
INFORMATION!
If there is a risk of water hammers in steam networks, appropriate condensate separators must
be installed. Suitable measures must be taken to avoid water cavitation if it is a possible risk.

Figure 2-5: Downstream pipe and outlet
CAUTION!
Installing the device in a downstream pipe 3 or upstream pipe of an outlet 4. There is the risk of
partially filled pipes leading to inaccurate measurements.

2 Condensate
DANGER!
Prohibited: Installing the device in a lower pipe bend 1, because there is a risk of condensate
forming 2.
Condensate can lead to cavitation and inaccurate measurement. Under certain circumstances
the device can be destroyed and the measured product can leak.
OPTISWIRL 4200
2.5.3 Pipelines with control valve
INFORMATION!
To ensure smooth and correct measurement, the manufacturer recommends not installing the
measuring device downstream from a control valve. This would run the risk of vortex formation,
which would distort the measuring result.
Figure 2-6: Pipeline with control valve
1 Recommended: installing the device before the control valve at a distance of ≥ 5 DN
2 Not recommended: Installing the flowmeter directly downstream of control valves, due to vortex formation.

INFORMATION!
The interior of the pipe at the metering points must be free of burrs and other flow impediments.
The measuring device has an internal temperature sensor. The distance from external
temperature measuring points must be ≥ 5 DN. Use flow sensors that are as short as possible to
avoid disturbances of the flow profile.
2.8 Flow straightener
If, due to the type of installation, the required inlet sections are not available, the manufacturer
recommends using flow straighteners. Flow straighteners are installed between two flanges
upstream of the device and shorten the required inlet section.

2.9.1 General installation notes
CAUTION!
Installation, assembly, start-up and maintenance may only be performed by appropriately
trained personnel. The regional occupational health and safety directives must always be
observed.
The following procedures have to be carried out before installing the device:
• Ensure that the gaskets have the same diameter as the pipelines.
• Note the correct flow direction for the device. This is indicated by an arrow on the neck of the
flow sensor.
• On measuring points with varying thermal loads, the devices have to be mounted with stress
bolts (DIN 2510).
• Stress bolts or bolts and nuts are not included in the scope of delivery.
• Ensure that the measuring flange is concentrically fitted.
• Note the exact installation length of the measuring device when preparing the measuring
point.

3.3 Electrical connections
The signal converter is a 2-wire device with 4...20 mA as output signal. All other inputs and
outputs are passive and always require an additional power supply.
3.3.1 Power supply
INFORMATION!
The supply voltage has to be between 12 VDC and 36 VDC (12...30 VDC for Ex). This is based on
the total resistance of the measuring loop. To calculate this, the resistance of each component in
the measuring loop (not including the device) must be added up.
The required supply voltage can be calculated using the formula below:
= RL * 22 mA + 12 V

To ensure the value ranges, a load RL between 250 Ω and 1 kΩ is recommended for the passive
transistor output with a nominal voltage of 24 VDC. If other loads are used, caution is advised as
the range of values of the signal voltages then no longer corresponds to the range of values for
the inputs of process control systems and controls (DIN IEC 946).
CAUTION!
The upper limit of the signal current must not be exceeded as this may damage the transistor
output.
For selection of measurement variable and adjustable data of the limit switch refer to chapter
"Menu description C - Setup", menu "C2.2.5 Limit Switch" and appropriate submenus.

The connection is made between terminal M2/4 Common (-) and M1 for Hi Current (+) or M3
NAMUR (+). Only one of the two connections M1 or M3 can be selected in menu C2.2. The output
is selected as pulse or frequency output in menu C2.2. The output is a passive "open collector"
output which is electrically separated from the current interface and the flow sensor. It requires
its own power supply 2. The total resistance must be adapted so that the total current I
tot
does
not exceed 120 mA.

3.5 Grounding connections
The grounding can be done either by connecting the PE (Protective Earth) terminal in the
housing or the PE terminal on the connection piece between flow sensor and signal converter.
Both of these electrical connections are equally effective from a technical point of view.

CAUTION!
The measuring device has to be grounded properly to achieve accurate measurement. The
grounding wire may not transfer any interference voltage.
Do not use this grounding cable to ground any other electrical devices.

The signal converter electronics housing meets the requirements for IP66/67 in accordance with
EN 60529 both for the compact and for the remote version.
CAUTION!
After all servicing and maintenance work on the measuring device, the specified ingress
protection category must be ensured again.

Figure 3-10: Cable feedthrough
Therefore it is essential to observe the following points:
• Use only original gaskets. They must be clean and free of any damage. Defective gaskets must
be replaced.
• The electrical cables used must be undamaged and must comply with regulations.
• The cables must be laid with a loop 1 upstream of the measuring device to prevent water
from getting into the housing.
• The cable feedthroughs 2 must be tightened. Note that the clamping range of the cable
feedthrough corresponds to the outer diameter of the cable.
• Align the measuring device so that the cable feedthrough is never facing up 3.
• Close any unused cable feedthroughs using blind plugs 4 suitable for the protection category.
• Do not remove the required cable bushing from the cable feedthrough.
