3The 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.INTRODUCTION

6The WFS is typically installed near the point of connection, in an appropriately-sized FCT Tee. The WFS transmitter can connect to a host con-troller 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.SYSTEM OVERVIEW AND WFS OPERATION

For international applications, optional slip-BSP adapters are available separately for sizes up to 75 mm.
9Install 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 down-stream direction (toward the sprinklers).INSTALLATION
10• 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.• Install the WFS and FCT assembly in a sturdy irrigation valve box. • WFS has an impeller which 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 WFS to protect the impeller from rocks or stones, which may damage the impeller.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.Metric thread adapters are available and are listed in this manual on page 8.Avoid excess glue when attaching fittings. Uncured blobs of excess glue on the fitting’s interior can interfere with paddlewheel operation.
11EXAMPLE OF INSTALL *NOTE: Not to scale.
12The FCT tee fitting comes with a plug that allowsfor installation of the FCT into the irrigation system prior to installing the Sensor. This allows the FCT tee to be installed separately from the sensor and prevents damage to the sensor during installation of the body.NOTE: Do not attempt to remove the sensor plug or sensor while the system is under pressureTo install the sensor into the body:1. Turn the system pressure o. 2. Unscrew the cap from the top of the FCT (gure 1).3. Use pliers or a screwdriver and carefully pry the plug from the FCT tee.4. Insert the sensor into the FCT. The sensor has a at side that engages with a at on the inside of the sensor body (gure 2).INSTALLING THE WFS SENSOR INTO THE FCT FITTING

14CONNECTING THE WFS TO THE IRRIGATION SYSTEMWARNING! WFS is only designed for low-voltage connection to approved irrigation controller flow terminals. Do not install in high-voltage 110V or 230V circuits.WFS has one wire lead which leads to the transmitter. The transmitter may be placed up to 500ft/152m from the controller.Connecting the ReceiverPro-CWire the leads from the receiver to the SEN terminals.

Proper irrigation system design and operation assures optimum performance of the WFS in monitoring for potential high flow conditions. WFS is primarily designed to shut off the irriga-tion system in the event of a catastrophic system failure such as a main line or lateral line break. However, depending upon the design of the irrigation system, the WFS can offer increased protection when components such as sprays or rotors are damaged or removed due to vandal-ism. The following may be helpful in making your WFS operate at its optimum level. 16
17SYSTEM CONSIDERATIONSWorking With WFSHunter flow-capable controllers are designed to measure and record actual flow, shut off irrigation when a high flow condition occurs, and identify which stations caused the condition.The controller’s Learn mode samples each station individually, and learns a typical flow for each station in the system. During actual irrigation, the flow can be observed at the controller. Actual flows are recorded and stored in the controller facepack. The ACC or I-Core controller will also compare actual flows to the estimated total of all active stations, to see if there is an unacceptable difference, indicating a leak or break.Consult the controller documentation closely for setup and operation of flow monitoring. It is vital to set the correct pipe size, so that the controller interprets the flow data correctly. It is also important to set adequate overage amounts (minimum is 15% over normal) and delays (default is one minute) to prevent false alarms.
18Mainline Pressure FluctuationSome water sources may have varying pressure depending upon the demand for water upstream of the point of connection. During times of heavy demand, system pressure through the mainline may drop.This is why the flow limit percentage and delay periods (set in the controller) are important, as false alarms lead to a lack of confidence in the system. Additionally, excess air in irrigation piping causes the WFS impeller to spin freely during station startup, which may cause temporarily high readings. This problem may be reduced by installing check valves in the system, and by setting the alarm delay values to prevent premature alarms.
19Proper System Maintenance and OperationIt is important that your irrigation system be maintained and is functioning properly for optimum performance. Check your irrigation system for any broken components or leaks also, making sure that all sprinklers are operating within the pressure ranges recommended by the manufacturer.
20Hunter controllers equipped with flow terminals will have approximately 20 VDC present on the flow sensor terminals, with no flow input.When flow begins, the voltage will pulse. On a standard voltmeter, the voltage will appear to drop, or pulsate. On voltmeters equipped with a frequency counter, the pulse frequency can be measured in Hz.
