Save time and fuel

Check your tanks without driving out.

HiLo uses radar to measure your tank level and sends it straight to your phone. You only head out when a tank needs attention, which saves time on water runs and money on fuel.

Low-water and leak alerts

Know when your water is running low.

Get an alert when your water runs low, or when the level drops quickly, which can signal a leak, so you can act before it becomes a problem. HiLo checks your tank every 15 minutes, and alerts are sent by app, email or text to everyone on your team.

Contactless radar

No probes, no problems.

Our contactless radar technology means there are no probes or moving parts inside your tank, helping reduce wear and tear. There's no solar panel either, and HiLo fits plastic and concrete tanks up to 3.5 m tall, with a replaceable battery that lasts for 5+ years.

How HiLo works.

The monitor measures your tank level, the cellular network sends it, and the app shows you every tank, wherever you are.

Works out on the farm

HiLo sends your readings over the Spark or One NZ cellular network, and the connection is included in your subscription. If you're unsure about reception at your tank, send us the location and we'll check coverage for you.

From lifestyle blocks to large stations, farmers trust their water schemes to HiLo.

“HiLo takes all the stress out of worrying about water leaks, and unnecessary trips just to check.”

“The HiLo system has saved the scheme tanks once, as a power cut meant the pumps didn’t start up again when the power came back on.”

Wayne

“We can see when levels are dropping or if an alert has been sent out you can go and fix the problem.”

Common questions

How does the monitor measure the level in my tank?
HiLo Tank Monitors use a radar to track the distance to the water surface from the top of the tank. During the setup process, you enter the dimensions of your tank and this is used to give you a % level or volume in Litres.
Why are radar monitors better than traditional cable and probe based monitors?
Probe-based monitors have a realistic life of a maximum of 3 years before they need replacing. All probe-based monitors suffer from some degradation over time, therefore, manufacturers normally recommend routine cleaning and specify a routine 3 year replacement. Probe based sensors can't be used in dirty water, sludge, or corrosive chemical situations due to corrosion or fouling.
How many tanks can I have on my app?
There is no limit to the number of tanks you can have in your app. Once you have more than 10, a search feature appears to allow you to quickly find the tank you are looking for.
Can my staff have the app on their phone?
Of course. You can invite as many staff or other users as you need. It's easy to do this from the app, but if you find it tricky, our support staff can help you.
Can I change the battery?
Yes, the battery is easily replaceable and can be ordered from us at a cost of $55 + postage.
How do I know if I have coverage at my tank?
Our monitors use LTE-M1 provided by the {{}} network. If you're not sure if you have 4G mobile coverage at your tank, feel free to share your tank location with us and we can check for you.
Do I need to be in line-of-sight with my tank to check the level?
No, once you have set your monitor up, you can check the level from anywhere you have internet access.
How often do I get level updates?
Your tank monitor will check the level every 15 minutes. If it detects an alert level, it will notify you straight away. Otherwise, you'll get a full picture of what's happened in the tank every 6 hours. If you need to, you can reduce this time to 4 or 2 hours but this will reduce the life of your battery. You can change the update rate easily in the app.
