Are you still spending too much time and money checking your tanks manually? The Farmo Water Level Monitor provides precision depth tracking for tanks and reservoirs, giving you the data you need to manage your most precious resource. It is a battery-powered device with edge-processing technology and real-time alerts so you can detect leaks and empty tanks before they become a crisis, saving you time, fuel, and livestock.

Monitoring remote water tanks is a time-intensive task that often leads to discovering problems only when it's too late. The Farmo Water Level Monitor is a robust sensor designed to improve the guesswork. By using a hydrostatic sensor submerged at the bottom of your water source, it delivers accurate, real-time depth measurements directly to your phone. Use the Farmo App to monitor usage trends, detect leaks early, and ensure your system is always performing at its peak. 

Data Includes

  • Depth (m)
  • Percent Full

Alerts

  • Percentage Full
  • Rapid Fall Leak Alert

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

Simply mount the sensor unit to the top of your tank and drop the sensor into the water. The sensor measures the water pressure, which is then converted into a depth reading and reported back as a measurement. Once activated via the Farmo App, the device transmits level data at regular intervals, triggering immediate "Low Level" notifications to your smartphone the moment your reserves drop below your custom-set threshold.

How Our Customers Use Farmo to Stay Ahead

Retire the ‘Tank Bang’ Test

Stop driving from tank to tank just to bang and listen for a hollow ring. Check your exact water levels in centimeters and percentages right from your phone.

24/7 Leak Detection

Get notified of a "Rapid Fall" like a burst pipe or stuck trough valve, the moment it happens. The sensor identifies unusual drops (e.g., 15cm in 15 minutes) and alerts you before the tank is empty.

Plug-and-Play Setup

No technicians or complex wiring. Simply mount the level monitor to the top of your tank using the included steel bracket and drop the weighted pressure probe to the bottom.

Link to pump control

Use the Farmo App to link your tank data to a Farmo IoT Switch for remote pump control.

$11 per device/month (ex GST)

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

The monitor uses a high-precision stainless steel hydrostatic pressure sensor. You simply drop the weighted probe into your tank, and it measures the pressure of the water column above it. The device then converts that pressure into an accurate depth reading, which is sent to your Farmo App.

No.  The unit has a pre-installed NB-IoT/Cat-M1 SIM card. It operates on the same long-range cellular towers used by your mobile phone but with much better penetration through tank walls and over hills. If you have even a basic mobile signal at the tank site, the device will connect.

While the device typically reports status updates every few hours to save battery, it features "Edge Processing" intelligence. It "wakes up" every 15 minutes to check the level. If it detects a "Rapid Fall" (e.g., a drop of 15cm in 15 minutes) or hits your custom "Low" or “High” thresholds, it bypasses the schedule and sends an instant data update.

The battery will last +2 years. Battery status is displayed on the App and when required a new battery can be ordered from Farmo and installed by the customer.
