2.4 Functional description
The ow switch works by the calorimetric principle and is used to convert the ow velocity into an electric signal. In
factory setting, the instrument shows the ow value in m/s on the digital display. The following units are available:
■
%
■
m/s
■
l/min
■
m³/h
■
ft/s
■
ft³/min
■
gal(US)/min
■
gal(I)/min
Additionally, the instrument measures the medium temperature in °C or °F.
The instrument features the following output signals, depending on the conguration:
■
Two switching outputs
■
One switching output and one analogue output
■
Two switching outputs and one analogue output

3.1 Explanation of symbols
WARNING!
... indicates a potentially dangerous situation that can result in serious injury or death, if not avoided.
CAUTION!
... indicates a potentially dangerous situation that can result in light injuries or damage to property or the
environment, if not avoided.

3. Safety
Information
... points out useful tips, recommendations and information for ecient and trouble-free operation.
3.2 Intended use
The ow switch has been designed and built solely for the intended use described here, and may only be used accordingly.
■
Conversion of ow velocities into an electric signal.
■
No assembly in downpipes open towards the bottom.
■
Use in buildings and outdoors (avoid high ambient temperatures and direct UV irradiation).
■
Environment with max. pollution degree of 3.
■
Voltage supply of overvoltage category II.
The ow switch is used to monitor whether the ow exceeds or drops below specied ow values, e.g. to prevent
pumps from dry running. The analogue signal should only be used as a trend indicator in order to monitor process
changes, such as lter blocking.
Only use the ow switch in applications that lie within its technical performance limits.
→ For performance limits see chapter 9 “Specications”.
Refrain from unauthorised modications to the ow switch.
Any use beyond or dierent to the intended use is considered as improper use.
The manufacturer shall not be liable for claims of any type based on operation contrary to the intended use.
3.3 Personnel qualication
Skilled personnel
Skilled personnel, authorised by the operator, are understood to be personnel who, based on their technical training,
knowledge of measurement and control technology and on their experience and knowledge of country-specic regula-
tions, current standards and directives, are capable of carrying out the work described and independently recognising
potential hazards.
Special operating conditions require further appropriate knowledge, e.g. of aggressive media.

3.4 Use of accessories and spare parts
It is recommended to use original accessories and original spare parts from WIKA. Using accessories and spare parts
from third parties can lead to damage to the instrument or accidents, due to quality defects or other reasons.
WIKA assumes no liability for damage or accidents caused by a malfunction or unsuitability of accessories and spare
parts which do not originate from WIKA (e.g. non-compliance with the IP ingress protection of connectors). No warranty
claims can be made which arise due to a malfunction or unsuitability of any accessory or spare part from a third party.
3.5 Labelling, safety marks

4. Transport, packaging and storage
4.1 Transport
Check the ow switch for any damage that may have been caused by transport.
Obvious damage must be reported immediately.
4.2 Packaging and storage
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport (e.g.change in installation site, sending for repair).
Permissible conditions at the place of storage:
■
Storage temperature: -20 ... +80 °C [-4 ... +176 °F]
Avoid exposure to the following factors:
■
Direct sunlight or proximity to hot objects
■
Mechanical vibration, mechanical shock (putting it down hard)
■
Soot, vapour, dust and corrosive gases
■
Humid or wet environment
■
Hazardous environments, ammable atmospheres
5. Commissioning, operation
5.1 Mechanical mounting
Only use the ow switch if is in perfect condition with respect to safety. Prior to commissioning, the ow switch must be
subjected to a visual inspection.
Commissioning and operation of the instrument may only be carried out by skilled personnel, see chapter 3.3 “Person-
nel qualication”.
