2. Note

Please read these operating instructions before unpacking and putting the unit
into operation. Follow the instructions precisely as described herein.
The devices are only to be used, maintained and serviced by persons familiar
with these operating instructions and in accordance with local regulations
applying to Health & Safety and prevention of accidents.

When used in machines, the measuring unit should be used only when the
machines fulfil the EC-machine guidelines.

as per PED 2014/68/EU

In acc. with Article 4 Paragraph (3), "Sound Engineering Practice", of the
PED 2014/68/EU no CE mark.

3. Instrument Inspection

Instruments are inspected before shipping and sent out in perfect condition.
Should damage to a device be visible, we recommend a thorough inspection of
the delivery packaging. In case of damage, please inform your parcel service /
forwarding agent immediately, since they are responsible for damages during
transit.

4. Regulation Use

These units, type SWK, are used for the purpose of measuring and monitoring
liquid flow. Only clean, low-viscous and homogeneous liquids may be measured
which do not chemically attack the materials used in the construction of these
units. An attempt to measure high-viscous liquids may lead to considerable
measurement errors.
Large dirt-particles can cause the blockage of float and subsequently turn on
error indications. Also, ferrite particles, which deposit on float (with embedded
magnets), can generate the same effect (we recommend a magnet-filter).

These units are configured in the following manner:

 Housing made of Brass, St. Steel or PVC
 Attached reed contact N/O with 1m PVC cable (Brass version)
 Attached reed contact N/O with 2m PVC cable (PVC/VA version)
 Attached and aligned pointer display (option)

5. Operating Principle

KOBOLD Flow Meter/Monitor of type SWK operates according to the well known
float principle, however without making use of the generally employed extended
measuring tube. Inside a cylindrical flow-tube a float with aperture moves in the
direction of the flow against the recoiling force of a spring. Within the float, a pair
of magnets is located which trigger a potential-free protective-gas reed contact
and drives a pointer display. The reed contact is mounted on the exterior of the
flow-housing. The springs arrangement allows the unit to be operated without
consideration to mounting position and keeps the installation dimensions to a
minimum. Flow monitors of type SWK generally find application where small
volume flow needs to be measured in a fail-safe manner.
