INTRODUCTION
The Hunter WFS allows flow-capable controllers, such as the Hunter ACC and I-Core, to monitor actual flow in irrigation systems.
With proper setup at the controller, this allows the controller to record and report actual flow in liters or gallons. Flow learning controllers can also use WFS to learn typical flow for each zone of irrigation, and monitor during watering for high and low flow conditions.
WFS equips controllers to respond on
their own to incorrect system performance, preventing damage to landscape and wasted water resources.

WFS COMPONENTS
This section will give you a brief overview of some of the components of the Wireless-Flow-Sync system.
1.Impeller: Rotates when flow is occurring
2.O-rings: Provides sealing of sensor in sensor body
3.Wire: Black wire connects to the sensor transmitter

WFS TEE ASSEMBLY
1.Flow-Sync Tee: The Tee is installed into the irrigation system and houses the WFS
2.O-rings: Provides sealing of plug in sensor body
3.Plug: (replace with WFS at Installation)
4.Cap: To seal plug to Flow-Sync-Tee

SYSTEM OVERVIEW AND WFS OPERATION
The WFS is typically installed near the point of connection, in an appropriately-sized FCT Tee.
The WFS transmitter can connect to a host controller up to 500ft/152M away.
WFS 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.
WFS Sensor is a reporting device, and does not respond to flow situations on its own. WFS is
almost always installed in conjunction with a Master Valve, which can stop flow in a damaged pipe when high flow conditions are detected.

INSTALLING THE WFS SENSOR AND FCT TEE
The WFS Sensor is designed to install within an FCT tee fitting, sized for the pipe in which it will be installed.
For international applications, optional slip-BSP adapters are available separately for sizes up to 75 mm.

INSTALLATION
Install the FCT tee fitting first, then install the WFS 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 WFS sensor, to prevent damage to the impeller.
•Always install WFS together with a Master Valve, to provide overflow protection.
•Install the WFS and Master Valve as near the point of connection to the water supply as possible.
•WFS 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 WFS (toward the water supply).
•There must be a length of straight pipe at least 5 times the diameter of the pipe in the downstream direction (toward the sprinklers).
