Flow
limits
In
the
meter’s
whole
working
range
from
min.
cut
‐
off
and
far
beyond
qs
there
is
a
linear
connection
between
the
flow
rate
and
the
measured
water
flow.
In
practice
the
highest
possible
water
flow
through
the
meter
will
be
limited
by
the
pressure
in
the
system
or
by
possible
cavitation
due
to
too
low
back
pressure.
If
the
flow
is
lower
than
min.
cut
‐
off
or
negative,
MULTICAL®
403
does
not
measure
any
flow.
According
to
EN
1434
the
upper
flow
limit
q
s
is
the
highest
flow
at
which
the
flow
sensor
may
operate
for
short
periods
of
time
(
1
h/day,
200
h/year)
without
exceeding
max.
permissible
error.
MULTICAL®
403
has
no
functional
limitations
during
the
operating
period
above
q
p
.
Please
note,
however,
that
high
flow
velocities
may
cause
cavitation,
especially
at
low
static
pressure.
See
paragraph
4.4
for
further
details
on
operating
pressure.
