Flow-Sync - FCT TEE

The Flow-Sync Sensor is designed to be installed within an FCT tee fitting, sized for the pipe in which it will be installed. Optional slip-BSP adapters are available separately for sizes up to 75 mm for international applications. Install the FCT tee fitting first, then install the Flow-Sync Sensor into the fitting.

The FCT tee fitting is designed for glue (“slip”) connection. Use approved PVC solvent-welding glue to install either threaded fittings, or directly into the irrigation pipe if desired.

  1. Minimum 10x pipe diameter from nearest turn-in system
  2. Mainline
  3. Flow direction
  4. Minimum 5x pipe diameter from the nearest turn in system

INSTALLING THE FLOW-SYNC SENSOR AND FCT TEE

IMPORTANT: Avoid excess glue when attaching fittings. Uncured blobs of excess glue on the fitting’s interior can interfere with paddle wheel operation.

FCT-Tee Installation Steps
  1. Install the FCT tee fitting first, then install the Flow-Sync Sensor into the fitting.
  2. Observe the following general rules when choosing the sensor location and preparing to install:
  3. Flush system with plug in place before installing the Flow-Sync sensor, to prevent damage to the impeller.
  4. 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.
  5. 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 (with no fittings) 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 (with no fittings) at least 5 times the diameter of the pipe in the downstream direction (toward the sprinklers).
    • Example: FCT-200 is installed in a 2"/50 mm diameter pipe. The tee should have 20"/50 cm of straight pipe upstream, and 10"/25 cm straight pipe downstream.
  6. Installing the Flow-Sync and FCT assembly in an irrigation valve box is recommended for ease of maintenance later.
  7. Flow-Sync has an impeller that will turn in the flow of water. If the water source is not a public water supply, add a filter upstream from the Master Valve and Flow-Sync to protect the impeller from rocks or stones, which may damage the impeller.

IMPORTANT: The Tee can be installed in any orientation, horizontally or vertically. There is no specific flow direction on the tee.
