The CF420
model is a flow transmitter that measures
the velocity of the flow. It is ideal for
use in measurement and control applications.
The CF420 provides two output options; a
4-20mA analog output and a PNP/NPN output.
For the 4-20mA output, the electronics'
module converts the signal from the probe
to a 4-20mA analog output, which can be
used to indicate flow rate. For the PNP/NPN
output, the measured flow rate is compared
to the set point value selected by the user
and the switch changes state once the set
point value has been achieved.
The
CF420´s microprocessor based electronics
and unique self-calibration program gives
the flow transmitter superior temperature
compensation, a fast response time 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 set
point 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 miss-aligned, accuracy will not be affected.
The sensing element and connection of the
CF420 are made with 316 S.S. and the enclosure
is glass filled nylon.
For
aggressive mediums the CF420 can be made
with Hastelloy-C. We do not coat any of
the CF420 models. The CF420 can be made
with a great variety of process connections
such as threaded, flange, or sanitary.
