3.0 Installing an SLFSI Flow Sensor to Main Line
3.0 Installing an SLFSI Flow Sensor to Main Line
A SmartLine Controller with a SmartLink Flow Aircard can
receive Flow data from ONE Flow Sensor. For additional
configuration options with multiple Flow Sensors,
contact your local Weathermatic representative or visit
Weathermatic.com.
1.
Install the SLFSI Flow Sensor on the system main
line after any Master Valve (Note: Master Valve not
required).
Available SLFSI Flow Sensor Models are:
SLFSI-T10
1" Tee
SLFSI-T15
1-1/2" Tee
SLFSI-T20
2" Tee
SLFSI-T30
3" Saddle
SLFSI-T40
4" Saddle
2.
Install the Flow Sensor on a stretch of main line that
will allow distance between itself and the next fitting,
turn, valve, etc. on both sides. The Flow Sensor must be
installed in accordance with the minimum distances that
are shown in the installation diagram.

3.
Install an adequately sized valve box over the Flow
Sensor for proper maintenance access.
4.
Use P-39 approved underground burial cable from
the Flow Sensor to the Aircard mounted next to the
controller. Maximum wiring distance from sensor to
the Aircard is 2000 feet (610m). The cable should also
be within an electrical conduit to protect wiring from
rodents, lightning, dirt and water. All wire connection
along the path must be made with 3M Scotchpack™
connectors or equivalent. Any deviation from these
specifications can cause faulty flow readings.
5.
Connect the underground cable to the Flow Sensor
using 3M Scotchpack™ connectors or equivalent.
Polarity is important! Connect the red to red and black
to back.
