Magnus HAWKi
The Magnus HAWKi is an award-winning, self-install radar gauge that delivers precise, real-time readings for fuel, water and other liquids - or even certain solids. Designed for quick installation and effortless use, it mounts without drilling and connects directly to your smartphone for instant access to tank information.
Highlights
- High-Precision Radar (±5 mm): Maintains accuracy in any weather and isn’t affected by condensation, temperature swings, or tank shape - outperforming typical ultrasonic sensors.
- App-Based Monitoring: Low-energy, long-range Bluetooth pairs with the Magnus app so you can check levels, set custom alerts and follow step-by-step guidance from your phone.
- Insightful Tracking: View daily consumption, analyse historical data and estimate how many days remain before the tank is empty.
- Smart Alerts: Background syncing warns you automatically of low levels, leaks or sudden changes.
- Shared Access: Give family members or colleagues the ability to view levels and receive notifications.

Important — please read
Please ensure the product you are ordering is the correct size and suitable for the purpose. Special order, bespoke and non-stock tanks are not returnable. If you order a tank and find it is too big, too small, or unsuitable for your requirements, it can be expensive to return. Our cancellation & returns policy explains this in more detail — see Terms & Conditions.

Looking to avoid shipping charges?
All our tanks are available for collection ex works. Our suppliers are based all over the UK — please call if you wish to collect.
Overseas orders
International orders are welcome. Payment is by IBAN / SWIFT / BIC, MoneyGram and letters of credit. We regret that credit cards are not accepted for international orders.
A purchase order is required; we will then create a pro-forma invoice, and tanks are ordered on clearance of funds.
If you require additional export documentation — for example a Certificate of Origin, or commercial invoices certified by the Chamber of Commerce — you must notify us before completion of your order, as we will have to invoice cost and admin charges to the order.
