Not necessarily. HAWKi does not require Wi-Fi for local Bluetooth monitoring. If you want to access HAWKi remotely, the optional Gateway uses Wi-Fi to connect it to the Magnus Cloud.
SENTRi does not require Wi-Fi, as it has built-in cellular connectivity. Suitable mobile network coverage is required at the tank location.
Yes, in many cases a level gauge can be retrofitted to an existing tank.
Yes. The Magnus radar monitors can measure through suitable plastic, allowing adhesive mounting on many plastic water tanks without cutting a hole in the tank. A suitable flat mounting position and clear measuring path are required.
Other gauges may require modifications to the tank in order to fit but in most cases this is straightforward.
Most of the gauges can be fitted to a metal tank. However, if using a radar gauge, the radar cannot measure through metal. The monitor needs to be fitted over a suitable opening so that it can measure the water below. Threaded mounting options for 1½" and 2" female BSP gauge openings are available.
Magnus specifies an accuracy of ±5mm for its radar tank monitoring technology. Radar provides non-contact measurement and is less affected by condensation and liquid turbulence than ultrasonic measurement
From simple visual indicators to advanced radar monitoring with smartphone access, our range makes it easier to see how much water you have available without manually checking inside.
Whether you need a straightforward gauge for a campervan or motorhome, or a smart monitor for a larger water storage or rainwater tank, we offer options for both local and remote water level monitoring.
Our range includes the Magnus HAWKi which uses high-accuracy radar and connects to your smartphone via bluetooth. We also have the Magnus SENTRi which provides remote tank monitoring using its own cellular connection - no Wi-Fi at the tank is required.
Knowing how much water is left in your tank can help you manage water usage, plan refilling and avoid unexpectedly running out.
The best way to monitor your tank will depend on the application. A conventional water tank level gauge may be all that's required for a campervan or smaller water tank, while a smart water tank monitor can provide more detailed information and smartphone access for larger or less accessible tanks.
Our Magnus smart tank monitors use 60GHz radar technology to measure the water level without the sensor coming into contact with the water. Magnus specifies an accuracy of ±5mm and a measuring range of up to 3 metres.
There are two main monitoring options:
Magnus HAWKi – connects directly to your smartphone using long-range Bluetooth, making it ideal for convenient monitoring when you are within range of your tank. An optional Wi-Fi Gateway can be added if remote monitoring is required.
Magnus SENTRi – designed for remote tank monitoring. SENTRi uses its own cellular connection to send readings to the Magnus Cloud, so Wi-Fi at the tank is not required. Suitable mobile network coverage is required at the installation location. Full SENTRi Installation guide …
Magnus smart monitors can be fitted to both plastic and metal water tanks, but the installation method is different.
Plastic tanks: The radar can measure through suitable plastic, allowing the monitor to be attached to a suitable flat area on top of many tanks using the adhesive mounting system. This means no drilling is normally required. Pre-drilled mounting options are also available.
Metal tanks: Radar cannot measure through the metal tank wall. The monitor therefore needs to be positioned over an opening with a clear path to the water below. Magnus provides threaded mounting options suitable for 1½" and 2" female BSP gauge openings.
For bunded tanks, the monitor must be positioned so that it measures the water level within the inner tank.
