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. Suggested Application

These units of type VKP are employed for flow measurement and monitoring of
H20 and viscous liquids in an economical way.
Only such liquids can be measured which are doped with impurities to a small
extent, and can withstand against the material used for fabrication of housing.
Significant errors in measurement may result if these devices are used for the
measurement of high-viscous media. Large-size impurity-particles may lead to
blockage of float element and thus are subjected to measurement-errors and
error-indications. The same problem may arise if ferrite particles deposit on float
element (with magnets).

These units are configured as follows:

Flow Measurement

The flow reading of the current value of flow is displayed on the scale sticked on
the housing. The upper edge of the float indicates the flow value.

Limit-value contacts (Option)

For the monitoring of the flow value the flowmeter can be equipped with an
adjustable limit switch.

N.O. function (increasing flow)
or N.C. function (increasing flow)
This contact is adjustable over the complete measuring range.
