The FSW-9000 Series is a flow
switch monitor that measures the
velocity of the flow. It is ideal for
use in measurement and control
liquid applications. The FSW-9000
Series provides two output options:
a 4 to 20mA analog output and a
PNP/NPN output. For the 4 to 20
mA output, the electronics’ module
converts the signal from the probe
to a 4 to 20 mA analog output,
which can be used to indicate flow
rate. For the PNP/NPN output, the
measured flow rate is compared to
the setpoint value selected by the
user and the switch changes state
once the setpoint value has been
achieved.
The FSW-9000 Series
microprocessor based electronics
and unique self-calibration program
gives the flow switch superior
temperature compensation, a fast
response time (adjustable from 3 to
10 seconds) and increased long
term switch point stability. Even in
the event of a power failure, the
calibration program will store values
for maximum and minimum flows
for up to 10 years.
A chain of 8 LED’s gives the user a
visual indication of the flow rate as
well as setpoint status, and one
di-chromatic LED indicates switch
point status. In addition, if there is a
problem with the unit, the 8 LED’s
will flash continuously providing
troubleshooting information.
The conical shape of the sensor’s
tip means that the probe can be
installed at almost any angle in the
pipe and that if the probe is
misaligned, accuracy will not be
affected. The sensing element and
connection of the FSW-9000 Series
are made with 316 SS and the
standard enclosure is glass-fillednylon. The FSW-9000 Series can
be made with a great variety of
process connections such as
threaded, flange, or sanitary and is
also available in an aluminum
enclosure for hazardous
environments. Intrinsic safety
barriers required for explosion proof
areas.
Measuring Ranges for
FSW-9000 Series
The FSW-9000 Series nominal
measuring range is 0.04 to 2.0 m/s.
The switch can be set to trip at any
value in this range. To calculate the
velocity for your application, use the
following simple formula:
V= (1.27 X Q)/D2
Q = Flow rate in meters per second
D = Pipe internal diameter in meters
V = Fluid velocity in meters per second
Please note that the 4 to 20mA
option is scaled over 0 to 2.0 m/sThe FSW-90-R is very similar to the
FSW-9000 Series with one main
difference: The sensor is separate
from the electronics and it does not
have an enclosed housing. This
gives the FSW-90-R Series the
ability to be installed in very small
pipes and be remotely controlled by
the FSCN-91 relay. The FSW-90-R
Series is the ideal solution when
there is not a lot of space to install
even a compact unit or when there
is a need for a mounted relay. In
addition, the conical shape of the
sensor’s tip allows the probe to be
installed at almost any angle in the
pipe, and if it is misaligned,
accuracy will not be affected. The
FSW-90-R is made with 316 SS.
FSCN-91 relay can operate with
DC or AC supply voltage and
provides an analog 4 to 20mA
and SPDT output. The FSCN-91
enclosure is made with ABS and
can be mounted on a DIN rail or by
using 2 fixing screws.
