Flow Meter Configuration
For
example,
the
Series
454PFTB
model
is
designed
to
directly
drive
a
solenoid
(up
to
12
W
at
24
VDC)
to
provide
the
compressed
gas
cleaning
to
the
sensor.
For
the
K
‐
BAR
2000PB,
only
one
of
the
sensor
control
boards
needs
to
have
the
solenoid
drive
modifications.
All
units
respond
to
the
external
trigger
command
at
the
same
time
and
mask
the
purge
blast
from
the
output
data.

Wiring for the Purge Controller
The
purge
controller
setup
requires
connecting
a
24
VDC
12
W
maximum
solenoid
to
the
DO2
or
solid
state
relay
channel
#2.
Pin
#
TB6
‐
1
is
+24
VDC
and
TB6
‐
2
is
the
GND
connection.
See
the
field
wiring
diagram
for
an
example
of
the
solenoid
wiring.
The
recommended
wiring
gage
is
18 AWG
(1.02
mm),
although
the
gage
and
length
are
not
critical
for
this
connection.
Note
This
wiring
information
only
applies
to
the
Purge
version
of
the
Series 454PFTB.
The
contact
closure
for
activating
the
purge
is
on
pins
TB6
‐
8
or
digital
input
1
(DI1)
and
ground
(TB6
‐
6).
The
width
of
the
activation
pulse
must
be
at
least
25 ms
long,
and
the
purge
will
start
on
the
leading
edge
(or
falling
from
logic
high
to
low).
