LS1-R Radar Monitor

The LS1-R is a highly configurable radar based level sensor. Designed for remote installation the LS1-R is ideal for open channel measurements.

The HiLo tank monitor uses groundbreaking radar technology to accurately monitor liquid storage levels. Using built-in cellular connectivity, the sensor transmits tank levels to the cloud so you can check your tank levels from anywhere.

Download the HiLo Mobile app from the App Store or Google Play for easy setup and access to your tank levels.Connectivity Options: If you have Spark or Vodafone 4G coverage at the site of installation, please select the appropriate network.

Key features

HiLo Radar Tech

HiLo is the original radar-based tank monitor.

[Insert content]

Cellular telemetry built-in

Whether you’re an owner-operator or a multi-property operator, HiLo helps you better manage your water resource.

Flexible measurement schedule

We have dedicated full-time support staff who can help over phone / email / text with installation, app support, and any other questions.

Adaptive Detection
Algorithms / ADA™

We know how busy you are on the farm, so we've designed HiLo to be easy to install and use. You don't need to constantly check the app. When there’s a problem, HiLo automatically sends you a text, email, and in-app notification with alerts for Leaks and High/Low tank levels.

Alarms with escalated reporting mode

Many competing products use probes inserted into the water tank to take liquid measurements. Probes can be unreliable, becoming rusty or requiring cleaning. HiLo units are designed to be reliable: free from probes and hassle.

Replaceable battery

Many competing products have non-replaceable batteries that limits the life of the unit. HiLo batteries are high-quality lithium batteries with a 10+ year lifespan - and are easily to replace in just a few minutes.

Trusted with monitoring critical infrastructure

Many competing products use probes inserted into the water tank to take liquid measurements. Probes have finite lifespans and can be unreliable, becoming rusty or requiring cleaning from sediment in the tank.

HiLo units are designed to be 100% reliable, with no probes and no hassles.

Key Specs (TBC)

The HiLo 4G monitor is an industrial-grade device, engineered for years of service in rugged rural environments. Whether it's baking hot, freezing cold, or under water during a flood, HiLO keeps measuring and sending data.

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.
