Install the FCT tee fitting first, then install the
Flow-Sync Sensor into the fitting.
Observe the following general rules when choosing
the sensor location and preparing to install:
• Flush system with plug in place before
installing the Flow-Sync sensor, to prevent
damage to the impeller.
• Always install Flow-Sync together with a
Master Valve, to provide overflow protection.
• Install the Flow-Sync and Master Valve as
near the point of connection to the water
supply as possible.
• Flow-Sync requires a section of straight
pipe on either side of the tee fitting to provide
accurate measurement of flow. Tees, ells,
and other fittings cause turbulence which
affects accuracy.
• There must be a length of straight pipe at least
10 times the diameter of the pipe upstream
from the Flow-Sync (toward the water supply).
• There must be a length of straight pipe at least
5 times the diameter of the pipe in the down-
stream direction (toward the sprinklers).
