| Problem | Cause | Solution |
|---|---|---|
|
WFS not reading. |
Water shut off. |
Verify that no isolation valves are closed, and that the water source is on. |
|
Controller not configured. |
Check controller flow sensor setup. Enter sensor size (and location for sensor decoders) and other sensor information as required. |
|
|
Damaged sensor, Impeller damage (debris in water) or WFS electronics damage (lightning). |
Turn off water supply, remove and inspect impeller. Verify that it spins freely and has no visible damage. |
|
|
Mismatching radio channels. |
Verify that the channel setting through the dipswitches for the RX and TX units are identical. |
|
|
Obstructed line of sight. |
Verify that the TX and RX units are not placed more than 500 feet away from each other and there is clear line of sight. |
|
|
Radio interference. |
Verify that any electrical or RF interference sources are away from the controller. Change channels if required. |
|
|
Dead battery. |
Replace battery. |
|
|
Receiver LED flashing green. |
Receiver is receiving flow data (green LED every 5 seconds). |
Not a problem; normal operation during flow. |
|
Receiver LED flashing red. |
Low battery (2 rapid red blinks every 3 seconds). |
Replace battery. |
|
WFS not reading correctly. |
Controller configured incorrectly. |
Set correct flow sensor size and type at controller. |
|
Turbulent flow at sensor. |
Ensure that straight pipe is on either side of flow meter. |
|
|
Frequent false alarms. |
Station settings too sensitive. |
Increase overflow percentage (and underflow, if available). |
|
Wide range of flows for a single station. |
Increase overflow percentages, and delay interval. |
