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.

Scope of delivery:

The standard delivery includes:

 Plastic Flow Meter model: KSK
 Operating Instructions

4. Regulation Use

Any use of the Plastic Flow Meter, model: KSK, which exceeds the
manufacturer’s specification, may invalidate its warranty. Therefore any resulting
damage is not the responsibility of the manufacturer. The user assumes all risk
for such usage.

5. Operating Principle

Kobold Plastic Flow Meters and Switches, model KSK, are based on the well
known suspended float principle.
They are used for measuring and monitoring flows in closed pipes.
The media flows, from below, through a conical plastic measuring tube. This
raises the float and the flow rate can be read off against scale. The instruments
can be fitted with bistable switches.
The use of high-quality material PVDF (model KSK 3...)means that this type is
very suited for service with corrosive media.

Special advantages

 Shock resistant and corrosion-resistant
 May be inserted/removed radially
 Special scales available
 Short installation length
 Plastic float and fitting generally made of PVDF

6. Mechanical Connection

Before Installation:

 Remove all transportation safety locks and ensure that no packing material

remains within the unit.

 Be sure that the maximum allowable operating pressure and temperature is

not exceeded (see Technical Data).

 Install the flow meter in the piping system, ensure the instrument is under no

mechanical stress/tension (install support bracing if necessary).

 Protect the measuring tube from external damage.
 Avoid pressure peaks in the measuring tube, e.g. from sudden surges or

stoppage of flow.

 The units with bistable reed switch may not be installed within an inductive

field.

 If possible, immediately after making mechanical connections, check whether

the connections are properly sealed with no evidence of leakage
(see section 8 Operation).

Detailed information regarding installation of float flow meters is
available in VDI/VDE guidelines 3513.
