Troubleshooting
There is water leaking.
The flow meter is threaded 1” BSP-G female both at inlet and outlet. It can be connected to any
hose commonly used for drip irrigation of watered crops.
hose commonly used for drip irrigation of watered crops.
Make sure to use proper female sleeves depending on hose size (Figure 8).
A Teflon® coating can be used on the pipe threads to ensure perfect sealing.
The flow sensor turbine is not rotating when water flows.
Make sure that the flow sensor direction is correct, as shown on Figure 6.
Besides, the flow sensor must be installed in a horizontal position (Figure 7).
Minimum flow rate is 3L/min (= 50 gph): below this flow rate, the turbine won’t rotate.
Turbine rotation can sometimes be blocked due to limescale or sediments in the water. In that
case, just shake the flowmeter firmly and blow it.

Magnet placed on the flow sensor: LED does not switch on (nor green, nor red)
Check that the magnet is placed on the right part of the flow sensor body as shown on Figure 1.
The magnet must touch the flow sensor body.
The magnet must be powerful enough: only use the magnet which was provided with the ITK
flow sensor.
flow sensor.
If it is still not working: see “Flow sensor is out of order” paragraph below.
LED stays on for more than a minute, or blinks continuously (green or red)
The flow sensor is out of order and must be replaced. One possible reason is that multiple “gateway
discovery” or “link check” processes were launched simultaneously using the same AgTech gateway.

Gateway discovery fails
If the red LED stays on for 5s at the end of the gateway discovery, it means that the flow sensor was
not able to successfully be paired with an AgTech gateway (Figure 2). Possible reasons are:
If the red LED stays on for 5s at the end of the gateway discovery, it means that the flow sensor was
not able to successfully be paired with an AgTech gateway (Figure 2). Possible reasons are:
The AgTech gateway is not running: switch the gateway on and relaunch gateway discovery.
The radio connectivity is not good enough: see Bad radio connectivity paragraph below.
The AgTech gateway is not properly configured (software, LoRa hub…): contact technical support.
“Link check” fails
If the red LED stays on for 2 seconds at the end of the “link check” process, it means that the flow
sensor was not able to successfully check its wireless link with the AgTech gateway (Figure 5).
Possible reasons are:
If the red LED stays on for 2 seconds at the end of the “link check” process, it means that the flow
sensor was not able to successfully check its wireless link with the AgTech gateway (Figure 5).
Possible reasons are:
The AgTech gateway is not running: switch the gateway on and restart the “link check” process.
The flow sensor is not paired to the AgTech gateway: first follow the “Gateway discovery”
instructions as shown on Figure 2, and then restart the “link check” process.
