The FSW-6000/7000 Series are
thermal flow switch monitors
designed to monitor flow status and
also used to detect level of liquids,
air and gas. A chain of 8 LED’s
gives the user a visual indication of
the flow rate. In addition, there isalso a dichromatic LED, which
shows the switch point status of the
unit. The sensing element and
connection of the FSW-6000/7000
Series are made with 316 SS. The
standard enclosure is
glass-filled nylon and is also
available in an aluminum enclosure
for hazardous environments. The
FSW-6000/7000 Series can be
made with a great variety of
process connections such as
threaded, flange, or sanitary.
The FSW-6000/7000 Series line of
thermal flow switch monitors is
based on the principle of thermal
dispersion. A typical configuration
uses two platinum Resistance
Temperature Detectors (RTD’s) set
within the tip of the sensor. One RTD
is heated a few degrees above the
temperature of the medium and the
other RTD is used as a reference,
sensing the actual process
temperature. The second RTD also
monitors the temperature of the
medium, as any changes in
temperature must be compensated
for in the first RTD. As the process
medium flows over the tip of the
sensor it disperses some of theheat from the first RTD. The
temperature change between the
two RTD's signals the probe’s
electronics and the switch changes
state once the set point has
reached.
The FSW-6000/7000 Series may
be installed in a pipe or tank using
the thread or connection provided.
Use only the hexagon when
tightening to achieve a seal, do not
use the body. The body should be
rotated after tightening to leave the
cable gland in suitable orientation.
The FSW-6000/7000 Series is not
affected by its fixing position so it
may be installed at any angle
around the pipe. However, it is
recommended that with horizontal
pipe runs the sensor should be
installed on the side, into the middle
of the pipe. In vertical pipes, the
FSW-6000/7000 Series should be
installed when there is flow in an
upward direction against gravity.
Care should be taken when
installing the sensor that the probe
extends clear of the pipe’s internal
wall and is fully immersed into the
flow. In pipes with smaller
diameters, some care should also
be taken so that the sensor is not
screwed too far into the line.
