Operation
The FX series flow switch is the most reliable
flow switch available. The thermal dispersion
principle of operation features no moving parts
and provides an extremely reliable and repeatable
switch for the most demanding industrial applications.
The sensor head employs two temperature sensors
with a constant very low power heating source
physically attached to one of the temperature
sensors. The second temperature sensor is isolated
from the heating source and provides compensation
for changing process temperatures. As flow changes
so does the temperature differential. This allows
the device to be used as a flow/no flow sensor
and to be used to switch at any velocity shown
in the flow switch range chart.
Extremely low flow rates can be detected with
range ability up to 300:1. These devices are
ideal for use in virtually all liquids, gases,
and slurries. The no moving parts principle of
operation assures reliable and repeatable operation
in extremely viscous products.
The electronics are available with single or
dual switch points. The instrument can be easily
field programmed to detect flow, level or temperature.
Relay outputs are standard and are offered with
several different configurations and contact
ratings. Remote mounting of the electronics is
available. |

FX
SERIES
The FX series flow switch offers the ultimate in
reliable and repeatable operation. The no moving
parts principle of operation allows these instruments
to be used in virtually all liquids, gases and
slurries. This line of thermal dispersion flow
switches can withstand temperatures to 900F and
pressures to 10,000 PSIG. Type 316L stainless steel
sensors are standard with options for exotic alloys
for corrosion resistance. Many different process
connections are available, including threaded,
flanged, and retractable probes. Typically this
series is used in 1/2” and larger line sizes with
our IX
series used in smaller lines. |
 |
IX SERIES
The IX series flow switch is an in-line device
designed to easily adapt to line sizes from 1/8" tubing
to 3/4" pipes. The thermal dispersion principle
of operation offers no moving parts exposed to
the process and provides an extremely reliable
and repeatable flow switch for the most demanding
industrial applications. These switches are used
to detect the increase or decrease of flow in virtually
all liquids, gases, and slurries. Applications
include monitoring flow to analyzers, gas chromatographs,
and chemical feeder pumps. Flow rates down to .01cc/second
can easily be detected.
|
 |
SX SERIES
The SX series sanitary flow switch has been designed
to meet the most critical flow detection applications
in the food, pharmaceutical, biotechnology, and
water treatment industries. Quick disconnect tri-clamps
are standard with special finishes for 3A applications
and polished/electropolished for biotechnology
and pharmaceutical use. The thermal dispersion
principle of operation features no moving parts
exposed to the process. The instrument can be used
to detect the increase or decrease of flow in virtually
all
liquids, gases, and slurries.

 |
FM
SERIES
The FM series is designed to provide an extremely
reliable flow switch at a very cost effective
price. This series replaces the standard explosion
proof enclosure utilized in our FX series with
a general purpose enclosure. The thermal dispersion
principle of operation provides no moving parts
exposed to the process and is capable of detecting
the increase or decrease in flow of virtually
all products. The field adjustable set point
can be used to detect flow/no flow or the set
point can be configured to alarm at a certain
flow rate. A relay output is standard providing
a SPDT contact with a 3
amp rating.
