Important:
Make sure that the specied maximum permitted operating pressure of the ow meter
cannot be exceeded, whatever the operating mode of the system. Note the ow meter
range that is dependent on the viscosity of the uid to be measured.
Important:
Make sure that the ow meter is always completely lled both in inow and outow and that
the outow has a little back pressure. This prevents the meter being damaged by a sudden
and steep increase of ow and at the same time improves measurement accuracy.

Please ush out the pipe lines and the tank thoroughly, to prevent contamination with
the ow meter.

Important:
When mounting the ow meter, you must take great care that the seals are not damaged
and correctly placed in the hydraulic connections of the ow meter. Wrongly installed or
damaged seals lead to leakage and to an leaky system, which may have dire consequences.
Please make sure that ow meters with EPDM seals do not come into contact with oil and
greases on a mineral oil basis. These uids can decompose the seals.
The yellow plastic plugs in the hydraulic connections of the ow meter protect the meter
against dirt and contamination during storage and shipping. Before mounting the ow meter
you have to remove these plugs so that in- and outow is free and open.
• Cleaning and ushing of pipe lines before initial start-up
Before initial start-up of the ow meter, you must ush and clean the
whole system Contaminateduids can affect the correct functionof the

For information on lter size for ow meters with plain bearings, in spe-
cial version, or with specially adjusted meter tolerances, please consult
VSE GmbH.
Important:
A blocking ow meter can stop the whole ow. You have to provide a control
valve / bypass for the system.

Important:
Please make sure that no extra inductive elements are connected in the power supply of
the ow meter, such as contactors, relays, valves etc. These components are potential
sources of interference (especially if the inductive elements are not provided with an
adequate protective circuit), generate high interference pulses, when switched and can
interfere with the functioning of the ow meter, although this complies with the electro-
magnetic compatibility directives.

Working life is dependent on operating conditions and thus the specic properties of the
devices, limited through wear, corrosion, deposits or age.
The operator is responsible for regular control, maintenance and recalibration. Any
indication of a malfunction or damage prohibits any further use. On request, we can supply
you with a borrowed device for the duration of repair or overhauling.
We advise to a yearly control and recalibration.
