Overview:

This procedure allows the Flow Sensor and associated wiring to be tested independently of an Irrigation Controller. A Battery and Resistor combination is used if no powered controller is available for the voltage and frequency measurement tests.

When broken up into its component parts, an irrigation system consists of the following elements: Controller, Wiring/Splices, and Sensor, for two-wire systems, also decoders.

The purpose of this procedure is to isolate the elements to rule out each as the cause until the actual failure cause is isolated.

The procedure consists or four parts. If the complete circuit fails any of the test steps, isolate the flow senor by breaking the last splice closest to the flow sensor, and repeat test on the wiring and sensor separately in order to determine if the problem is with the wiring or the sensor itself.

1 Check controller settings for correct Flow Sensor installation

2. Testing wiring to the flow sensor for ground faults resulting from moisture penetration into the wiring, splices, or sensor itself.

3. Testing for broken or shorted wires, splices, or problems internal to the sensor itself

4. Confirming frequency output and confirmation of actual flow rate sensor is reporting.

Test Equipment:

(Battery and Resistor are not required if Controller is operational)

Troubleshooting Guide FS Series Flow Sensors

1. Multi-meter with Ohms, Volts, and Hz (Radio Shack Model 2200075 (shown) or Equivalent)

2. 1K Resistor ( Radio Shack 271-1118 or Equivalent)

3. 9 Volt Battery

4. Connector clip for 9V Battery (Radio Shack 270- 325 or Equivalent)

If an operational flow meter or controller is not available, it can be simulated with a Battery and Resistor. Connect one end of the 1.0k resistor to the Red Battery Clip wire, and the other end of the resistor to the Flow Sensor + Wire (Usually Red or White). Connect the Black Battery Clip Wire to the Flow Sensor (-) Black Wire. Follow the directions, the same as if the controller was powering the sensor.

STEP ➋STEP ➊ STEP ➍

Test for Voltage on the Sensor Wires

1. At the controller end, completely disconnect any and all wires running to the flow Sensor.

2. Set multi-meter on its Auto-Ranging Voltage setting.

3. Connect the multi-meter Black wire to Earth Ground (This can be a pipe, fence, grounding rod, or building steel beam). Electrical panel ground can also be used if available.

4. Touch the Red Multi-Meter test lead to each of the Flow Sensor Wires one at a time, and take note of the reading.

Check Controller Settings for Correct Flow Sensor Configuration

1. At the controller, turn the dial to “Module Programming”. The LCD screen should display “Flow Smart Module”.

2. Press “Next”. The LCD screen should display:

“Flow Sensor Setup” and “SEEF/SELF Settings”, etc. Select “Flow Sensor Setup” and press “Next”.

3. The LCD screen should display:

Flow Sensor Setup

Type:

Back Next+ -

* “Disabled” or “Custom” or “FS050P” or “FS150P” or “FS350B” or etc…

4. Make sure that the settings are representative of the installed flow sensor.

For “Custom” settings of k-factor and offset factor, please contact flow sensor manufacturer. For Rain Bird’s flow sensors, please chose the appropriate flow sensor from the provided list.

Test for Broken or Shorted Wires, Bad Splices, or Internal Sensor Problem

1. If controller is operational, measure the Open Circuit voltage on the terminals to which the flow sensor will be connected. If not, use the Battery Resistor combination shown above, and measure the voltage, between the open end of the resistor and the black battery clip.

Connect the flow sensor and with no flow, re-measure the voltage on the same terminals.

The sensor draws about 0.6mA, so the voltage should be slightly less than measured open circuit. For example, the Battery Voltage would have been about 9.1VDC, so with 0.6mA flowing through the 1k resistor the expected voltage across the flow sensor would be 8.5VDC. Since controllers vary on design, voltages will vary.

However, the following list may be helpful and a general guide.

Test for Ground Faults

1. Confirm that the controller is still completely disconnected from any and all wires running to the Flow Sensor.

2. Set multi-meter on its highest OHM’s scale, and short its Red and Black test leads together to confirm proper operation.

3. Connect the multi-meter Black wire to Earth Ground (This can be a pipe, fence, grounding rod, or building steel beam). Electrical panel ground can also be used if available.

4. Touch the Red Multi-Meter test lead to each of the Flow Sensor Wires one at a time, and take note of the reading.

Measure Flow Rate in HZ and convert to GPM

1. Establish a flow of at least 1 Ft/Sec to insure the impeller rotates.

2. Without moving the Multi-meter leads from the connections of Step#3, switch the Multi-meter to read Frequency ( Hz).

3. Note the Hz reading, and estimate the actual expected flow rate at the time the measurement was taken.

4. Locate the K and Offset values found in the Flow Sensor owner’s manual. For example, if the flow sensor was a 228 Series 2” PVC ➞ K = 2.8429 Offset = 0.1435

5. Use equation to convert Hz to GPM:

GPM = (Measured Hz + Offset)*K

If for example 23.5 Hz was measured in this 228PV-2 sensor:

GPM = ( 23.5 + 0.1435) * 2.8429 = 67.2 GPM

6. Compare the computed flow rate with the expected flow rate, and as shown on the controller or monitor if operational. If all are in agreement, everything is working properly.

STEP ➌

STEP ➎

Is the voltage greater than a few milli-volts? YES

NO

Did the voltage drop about ½ to 1VDC?

YES

NO

Was there no change in voltage?

YES

NO

Was there a drop to less than 1VDC?

YES

NO

Is the voltage unstable?

YES

Is the resistance lower than 1 Meg Ohm? NO

YES

This suggests a problem with the wiring. Confirm that these wires really do run to the flow sensor and not to something else.

Indicates a broken wire, splice, or internal problem with the sensor.

This is normal.

Continue to Step 4.

Indicates a Short in the wiring or sensor.

This may indicate flow in the pipe, something is interfering with normal operation, an intermittent connection, or internal problem in the sensor itself.

Anything less than 1 Meg Ohm suggests a problem with either the wiring, splices, or flow sensor itself.

Model for K Offset Suggested Operating Range (gpm)

Update settings and check flow sensor operation.

FLUSHING

• Flush the system every two weeks for the first 6 weeks and check the water that is flushed out for cleanliness

• Establish a regular flush schedule for the future after these initial checks

• Flush the system well after any repairs are made

• Check the pressure at the supply and flush headers on a regular basis and compare with the pressure readings taken right after installation

• Winterizing an irrigation system involves removing enough water to ensure that components are not damaged due to freezing weather

• Check the manufacturer’s instructions for winterizing the valves, filters and backflow prevention devices

If compressed air is used to blowout the lines:

• Compressed air may be used only be used with the flush valve open and with the air pressure at 40 psi (2.76 bar) or less

• XF Series Dripline fittings are rated to 50 psi (3.45 bar), so the air pressure must be adjusted below this pressure

• It is air volume, not pressure, which is effective when blowing out the lines

• The pressure-regulating valve that is part of the control zone regulates water, not air pressure

• After turning off the air, close all drain ports

If compressed air is not used to blowout the lines:

• A drain port should be installed at all low points in the zone. These ports may be a tee or elbow with a threaded plug or a manual flush valve

• If the zone is in a grid or closed loop system, the headers may contain a significant amount of water because they are either blank XF Series tubing, PVC, or poly pipe. It is important to provide drain ports for these components

be opened to drain at the lowest point(s)
