Monitoring water flow across a property is often impossible until you see a flooded paddock or an empty tank. The Farmo Water Flow Monitor is a rugged, inline turbine flow meter designed specifically for the tough Australian environment.

It provides high-precision data (+/- 5% accuracy) on flow rates ranging from 10 L/min up to 300 L/min. The device uses "Edge Processing" to check your flow constantly, reporting every 15 minutes while water is moving.

Option available to purchase the Telemetry only. This includes SIM card, battery and pulse counter to be retro fitted to an existing flow meter with pulse output. Please confirm compatibility and pulses/litre for configuration.

Data includes 

  • Flow Rate (L/m)
  • Flow (L) periodic amounts
  • Flow Today (L) cumulative amount per day

Alerts 

  • Flow Rate 
  • Flow Today

Farmo technology is not intended to replace human oversight but can allow much more frequent monitoring and provide historical insights for analysis.

Installation is straightforward: The sensor is installed inline into your existing pipework, designed to fit 2" poly pipe or 1 ½" with the included size adaptors (note: rural poly fittings are not included).

Once installed and activated via the Farmo App, it begins counting pulses to calculate flow rate and total volume. The monitor stays in a low-power state to save battery, waking up instantly to transmit data the moment water starts flowing.

How Our Customers Use Farmo to Stay Ahead

Detect Major Line Failures

Don’t wait until a paddock is underwater or a header tank is bone dry to realize a main line has ruptured. Get an immediate notification if flow spikes above your custom safety threshold, allowing you to shut off the pump before the damage is done.

Identify Hidden Leaks

Get the heads up on leaks especially in winter when the wet spots won't be visible in the paddock.

Monitoring Stock Water Supply

Use flow meters on trough lines, header tanks and supply pipes to confirm water is actually moving to livestock areas, spot abnormal drops in usage, and reduce the risk of animals being left without water.

Pump Management and Automation

Support automatic control systems that start, stop or change irrigation flows. This is relevant where pumps and outlets are automated with the Farmo IoT Switch or Smartplug.

The electric fence sensors and water rats have provided peace of mind knowing that the cattle are where they should be and with water in the troughs.
Great customer support when I experienced issues with fence sensors.

jeanette

I had a real problem getting accurate and up to date rain data on our farm in far east Gippsland when I spend most of the time in Melbourne. The rain gauge through Farmo solved the problem and the support and backup with questions was great

Mick

We have been using Water Rats for a number of years to monitor outlying or problem troughs. This has proven to be very successful giving peace of mind that water is available for cattle at the specified locations. We have had no issues with the flexiblity, reliability of the Water Rat. It is also helpful that we are linked in via Agriwebb.

malcolm

The "Water rat" is a simple unit that works well.
No installation. Easy to shift from one trough to the next.
Our unit stopped working, & Farmo promptly replaced it with a new unit, no hassles.

Michelle

Great tank monitoring system

Mitchell

Having a level meter on our water tank has meant so much to us in the last 12 months. There’s a huge sense of security in being able to detect unusual level changes, both monitoring the activity of our solar pump and also, during the dry season, the demand on our storage tank. Definitely a really worthwhile investment. Thoroughly recommend this little device.

James

Farmo has been great to deal with—excellent customer service and a team that genuinely cares. Their technology is simple to use and maintain, making it perfect for agriculture. Reliable, well-designed products and great support. Highly recommend!

Bryce

We had issues connecting with the WaterRat when we activated it but, working with customer service they quickly resolved the problem. The WaterRat was a cow life saver!! Our landowner, for some reason, shut the water off while we were away. The WaterRat alerted us when the tank was low and the device tipped on its side, with a stretch of 30+ weather it was worth its weight in gold!! Customer service is amazing!! I will be ordering more for all our pastures.

Dux

We use Farmo water rats in our troughs to keep an eye on the water levels . We can easily move them , as simple as taking them out and throwing them in the next trough as the cattle move paddocks . We can set alerts on our phones to let us know if a trough is empty . With tests they send the alert text within 10 seconds of tilting . They are very easy and cost effective.

FAQs

Yes, as long as there’s mobile network coverage (Telstra by default) the device will work. Data is sent over the specialised long distance CatM1/Nb-IoT part of the 4G and 5G networks, so you will find coverage goes further than voice calls on handsets.

If you are comfortable working with poly pipe and rural fittings, you can install it yourself. It fits directly into a 2" poly pipe (or 1.5" with adaptors). However, we always recommend a professional installation if you are cutting into main pressurized lines or complex irrigation systems.

The data is updated every 15 minutes when water is flowing. If no flow is detected, the device sends a daily (24-hour) heartbeat report to confirm it’s still online.

You can configure alerts in the Farmo App by choosing whether to receive SMS and/or email notifications, and by setting which phone numbers or email addresses should get them. Automated phone call alerts are also available on request.
