The WX1 and WX2 Tap Timers feature a flow counting wheel on the outbound side of the timer. This wheel spins during watering offering a flow reading, the measurement is published as 'Last Water Flow' onto the status page for the tap timer after watering.

The accuracy of the flow meter is dependent on operational conditions for the timer, as well as your watering set up.

• 50-800 kPa working pressure
• 3oC - 50oC working temperature
• Maximum flow rate from your tap of 25Lpm

Flow reporting from a normal system (not pressure compensating system)

You need to achieve a system output at/above 7L per minute (LPM). Anything less than 7LPM from the watering system will be inaccurate and then below 5LPM may even be non-existent.

This is due to the speed of the flow counter. If it slows too much (or stops) due to low flow (and lack of water movement) then it can’t report.

This can happen on a very short system (below 10m) or one with a low output dripper (for example watering a few pot plants).

Flow reporting from a pressure compensating system

When you connect a pressure compensating system, your flow will be inaccurate and, in some cases, non-existent - depending on the total output from the system.

When the water is being released, it's being released in small increments which don't generate any movement on the flow wheel.  What happens in these systems is that the poly/hose fills with water and then the water just sits - there's far more water on offer than is being let through the drippers, and the flow wheel of the tap timer is stopped in this process. 

1. Check the Filter

• 🧵 Locate the wire mesh filter at the top of the timer.
• 🧽 It may need descaling or cleaning to remove mineral build-up or debris.

🧪 2. Prepare a Cleaning Solution

• 🧴 Mix a 50/50 solution of vinegar and water, or use a mild CLR solution.

🚿 3. Clean the Timer

• 🔧 Remove the timer from the tap.
• 💦 Shake out any excess water.
• 🪑 Place it on a flat surface (like a bench).
• 🥄 Pour the solution into the top of the timer and let it sit for 10 minutes.
• 🔄 Flip the timer upside down and repeat the process for the bottom.

🔁 4. Flush the Timer

• ⏱️ Use the MANUAL function to flush the solution through the body of the timer.
• ✅ Once flushed, your timer should be clean and ready to go!

If this does not help, the timer is under a 2-year warranty period, you can use your receipt or let us know the 4-digit batch number form the battery holder or back of the battery cover.
