Flow-Sync is typically installed near the point of
connection, in an appropriately-sized FCT Tee.
Flow-Sync can connect to the host controller
via two direct burial-rated 18 AWG/1 mm wires up
to 1000 ft/300 m away from the controller.
Flow-Sync can also connect to ACC99D family
decoder controllers via the ICD-SEN sensor
decoder, and report up the same two-wire path
used by the ICD station decoders. Flow-Sync
does not require any additional power source.
Flow-Sync sensors operate with an impeller
positioned in the flow through the pipes.
As the impeller turns, pulses are generated to
the controller, which converts them to gallons or
liters, depending on the Units of Measurement
selection in the controller.
Flow-Sync is a reporting device, and does not
respond to flow situations on its own. Flow-Sync
is almost always installed in conjunction with a
Master Valve, which can stop flow in a damaged
pipe when high flow conditions are detected.
