In the world of water management, keeping a vigilant eye on your water levels is paramount. Whether you’re a homeowner with a rainwater harvesting system or a farmer managing large water tanks, having a reliable method to monitor your water levels can save you from potential issues down the line. This article will explore five different methods to check water levels, each catering to different situations and needs.


1. Good Old Knock on the Tank


Starting with the simplest method, knocking on the side of your tank can give you an initial idea of the water level. By listening for a change in sound as you knock from top to bottom, you can estimate where the water line is. Though not the most accurate, it’s a quick and easy way to get a rough idea of your water level when other methods are not available.

2. The Visual Ball on Stick Gauge


Ideal for rural applications, this gauge consists of a float inside the tank connected to a pole with a high-visibility ball on top. As the water level changes, the position of the ball also changes, providing a visual indication of the water level. While it might not be the most precise, this quick visual indicator is extremely useful when a rough estimate is all you need.

An example of this type of gauge is the Longreach Tank Gauge. Designed to fit any type of tank with its adjustable mounting base and extendable stainless steel poles. Its high-visibility red colour and large bottom float ensure accurate readings and long-distance visibility.

3. The Trusty Tank Top Gauge


Moving up the accuracy ladder, we have the Tank Top Gauge. This type of gauge is often installed directly onto the top of a tank and includes a dial that moves in relation to the water level inside the tank, providing an accurate indication of the water level. The only downside is that you need to be within a few metres of the tank to read the gauge.

The Tank Gauge from Rain Harvesting offers an easy-to-read display that can be installed in various types of tanks.

4. The Reliable Sidewall Tank Gauge


Side wall tank gauges are known for their higher accuracy. They usually have a float inside the tank, a counterweight and a visual indicator on the outside which moves according to the water level inside the tank giving an accurate at-a-glance indication of your water level.

Rain Harvesting offers two robust options: the Side Wall Express Tank Gauge and the Side Wall Guided Tank Gauge. Both are designed to withstand harsh environments and fit any tank type, making them a versatile choice for any tank.

5. The Smart Gauge


These innovative devices operate by connecting to networks such as WiFi, phone networks, or even satellites to transmit data directly to an app on your smartphone or computer. This means you can easily check your water level or other monitored substance from anywhere, at any time, keeping you informed and in control, no matter where you are.

The Rain Harvesting Tank Gauge Plus is a popular example of a smart gauge specifically designed for monitoring water levels. This gauge offers features such as custom notifications, allowing you to set alerts based on your specific needs. Whether you want to know when your tank is nearly full to prevent overflow or when it’s nearly empty to avoid running out of water, the Tank Gauge Plus has you covered.

Furthermore, the Tank Gauge Plus provides connectivity options remotley via the SigFox Network or locally by Bluetooth. This ensures you stay connected and informed, whether you’re at home, at work, or on the go. The ability to accurately track inflows and outflows gives you a clear understanding of your water usage, helping you manage your water resources more effectively.
