A sensor sits in your tank and sends your levels straight to the FarmSense app, updated continuously. Know exactly what’s left, without ever driving out to check.

Proven on NZ farms
It’s one of the most popular sensors in the FarmSense range, trusted by farmers who’d rather know than guess.
“Since implementing the water tank level monitoring system, my workflow has changed for the better. I can check water levels directly from my phone, which has been a game changer. This flexibility allows me to focus on other important tasks around the farm while keeping an eye on our water supply.”
“The FarmSense system alerts me via text message if my water levels drop too low, giving me ample time to get on top of issues before they become problems.”
“Previously, I relied on a float gauge, which was often unreliable and left me scrambling when tanks ran dry. Now, I receive real-time alerts for any issues, such as pumps not running or leaks. This proactive approach has saved me invaluable time and effort.”
Driving out to check gauges
Time lost on manual rounds, every single day.
Leaks found a week too late
Thousands of litres gone before anyone notices.
Stock left without water
A dry tank discovered at the worst possible time.
Levels on your phone, continuously
Check every tank with your morning coffee.
A text before a tank runs low
Set a threshold and catch problems early.
Fix it small, before it’s expensive
Spot a leak the day it starts, not a week later.

Check your tank levels each morning alongside the rest of your farm, all in the one app. No more separate systems, no more second-guessing what's left.
The Sensor Hub
Your Water Tank Level Sensor plugs straight into a Sensor Hub which has a mobile sim card in it and relays data from up to four plug-and-play FarmSense Sensors via cellular.
Plug your sensor into the Sensor Hub and you're connected. No wiring, no callout, no fuss.
Lower the stainless probe into your tank from the top on its 5m cable.
Connect the sensor to your solar-powered Sensor Hub. That’s the wiring done.
Levels appear in the FarmSense app within minutes. Set your alerts and you’re done.
