Hydraulic
Groups
During
irrigation
"Greenkeeper"
tries
to
open
as
many
valves
as
the
pump
capacity
allows.
When
the
valves
are
not
assigned
to
a
hydraulic
group/sector
the
way
the
program
runs
is
controlled
by
an
algorithm
which
takes
into
consideration
the
flow
of
the
different
valves
but
disregards
the
pipe
network
arrangement
and
pipe
dimensions.
While
in
terms
of
irrigation
efficiency
it
would
be
bad
practice
to
supply
the
valves
that
are
in
operation
simultaneously
from
the
same
pipe
branch
(pressure
drop)
it
is
essential
to
give
Greenkeeper
the
information
about
which
valves
are
supplied
from
which
pipe
branch
and
what
the
permitted
maximum
flow
of
the
pipe
branch
is.
By
subdividing
the
pipe
network
into
hydraulic
groups
and
hydraulic
sectors
Greenkeeper
is
capable
of
making
optimum
use
of
the
pipe
network
resources.
Consequently,
the
irrigation
time
can
be
reduced
to
a
minimum.
