Please read and take note of these operating instructions before unpacking and
setting the unit for operation, and 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 with the prevailing regulation applying to
procedural safety and the prevention of accidents.
PED 2014/68/EU
In acc. with Article 4 Paragraph (3), "Sound Engineering Practice", of the
PED 2014/68/EU no CE mark.

3. Regulated usage
Model BVO and RVO instruments are used for monitoring of fluid flows. Only
clean, low viscosity and homogenous media may be measured, which do not
affect the materials used in the instrument casing. Large measuring errors will
occur when using high viscosity media. Large dirt particles can lead to blocking of
the float and therefore large measurement and signal errors. Ferritic particles that
deposit on the float body (with internal magnet) can also lead to a similar effect
therefore we recommend a magnet filter.
The instruments are provided as follows:
Flow measurement
The actual flow can be read locally at the instrument.
The scale shows the flow rate directly in litres per minute of water.
Limit Value Contacts
For the monitoring of the flow rate, the instruments can be fitted with one or two
adjustable limit value contacts.
Standard Design: Normally open (with rising flow)
Special Design: Changeover switch (SPDT)
Special Design: Ex-contact N/O, Ex-contact SPDT
The contact is adjustable over the full measuring range.
