Option 17 — Configured for Shifting Gases
Option
17
has
dual
‐
purpose
functionality
that
is
configured
per
user
specifications.
The
two
functionalities
are
mutually
exclusive,
and
the
specified
functionality
cannot
be
changed.
Important
This
section
contains
Information
for
configuring
the
flow
meter
for
a
shifting
gas
composition.
Information
for
selecting
from
the
available
list
of
multiple
gas
calibration
curves
starts
with
on
43.
An
optional
feature
available
with
Kurz
flow
meters
is
the
ability
to
adjust
for
shifting
gas
(also
referred
to
as
“binary
gas”)
compositions
or
to
select
a
different
predefined
gas
calibration.
•
A
shifting
gas
composition
is
a
gas
mix
with
only
the
percentages
of
the
gases
within
the
mix
changing
based
on
the
key
gas
within
the
mix.
•
Multiple
gas
calibrations
support
up
to
five
unique
gases
or
gas
mixes.
Important
Two
different
sets
of
parameters
appear
depending
on
Option
17
being
configured
for
the
shifting
gas
feature
or
the
multiple
gas
feature.
Make
sure
you
are
referring
to
the
correct
set
of
feature
parameters
for
Option
17.
Shifting Gas Composition
Shifting
gas
compositions
are
common
in
biogas
applications
where
the
amount
of
methane,
hydrogen,
and
carbon
dioxide
can
shift
based
on
seasonal
changes,
biomass
content,
and
rate
of
decomposition.
The
gas
composition
can
be
changed
two
ways:
•
Manually
by
entering
a
percent
concentration
of
the
key
gas.
•
Automatically
adjusting
the
percent
concentration
of
the
key
gas
through
the
4
‐
20
mA
external
input
signal
read
by
the
flow
meter.
The
factory
setting
for
the
shifting
gas
composition
feature
is
configured
so
that
the
percent
concentration
of
the
key
gas
is
entered
manually,
and
it
is
set
to
50%
concentration
of
the
key
gas.
Make
sure
to
properly
wire
the
flow
meter
electronics
before
changing
the
source
of
the
gas
adjustment
to
an
external
source.

input
signal.
