Introduction
CF12 AC / CF12 DC
Thermal Dispersion Flow
Switch Monitor
The CF12 series of thermal flow switches is designed to monitor flow status of liquids and
gases and can also be used to detect level.
Achain of 8 LED's gives the user a visual indication of the flow status of the switch. There are
two red LEDs that indicate whether or not the unit has detected flow, a yellow LED to indicate
the set point (for increasing or decreasing flows) and 5 green LEDs that indicate the amount
of flow beyond the set point of the unit. The CF12 also includes a di-chromatic (red/green)
LED which shows the switch point status of the unit.
The sensing element and connection of the CF12 are made with 316 S.S. and can be coated
when necessary . The enclosure is offered in either glass filled nylon or aluminium.
All models can be ordered with a great variety of threaded, flange, or sanitary procces
connections as well as Hallar or epoxy coating for aggressive mediums.
For Hallar coating we recommend that the switches are made with flanged connections or a
minimum of 1” threaded connection.
Simple to install.
Excellent low flow sensitivity.
Available in X-proof version.
No moving parts-maintenance free reliabity.
Can be coated for aggressive mediums.
Maximum working pressure of 1450 PSI (100 bar).
Fast response time for flow or level (Adjustable from 1-10 seconds).
Avaliable in threaded, sanitary and adjustable insertion length connections.

Pre-Installation
Pre-Installation Checks:
1) Its recommended that the flow switch is
installed with a distance of ½ a meter of the pipe
bent where the flow enters and 5x times the
diameter of the pipe where the flow exits, enabling
it to have an accurate reading (Fig. 1).
Verify that the installation point isn’t near any
connections, valves, elbows or anything similar,
this can cause errors in the reading of the probe
due to turbulence in the pipe.
2) It is important that the flow switch is not installed
at the highest point in the pipe run or in a location
where there is the risk of air accumulating in the
pipe. Keep in mind that the ideal mounting
location is where the pipe is always full. This will
ensure that the switch is always immersed in the
flow. (Fig. 2 correct, fig. 3 incorrect)
3) In pipes that have pressure pumps or retention
valves, we recommend that the probe be installed
before the pump due to the fact that it will have
less turbulence. (Fig. 4)
4) Confirm that the wire connections are correct
and that the available power supply is compatible
with the CF12 unit.
5) Verify that the operating pressure and
temperature of the process corresponds to the
operating parameters of the CF12 unit.

can be found on page 14.
