The Magnus HAWKi is an award-winning, radar-based tank monitoring solution designed for accurate, reliable level measurement across a wide range of fuels and liquids. Built with installers, merchants, and end users in mind, it offers fast, no-drill installation and dependable performance in domestic and commercial environments.
Using advanced radar technology, HAWKi delivers precise real-time tank level data directly to a smartphone via the Magnus App. Unlike traditional ultrasonic gauges, it is unaffected by condensation, temperature changes, or tank shape, making it a robust upgrade or replacement for existing oil tank monitors.

- Bluetooth long-range connectivity (up to 100m): Ideal for remote tanks and large properties.
- Smart monitoring via Magnus App: View live tank levels, usage history, and “days to empty”, with configurable low-level alerts.
- Continuous background syncing: Automatic updates and alerts for low levels, sudden drops, or potential leaks.
- Multi-user access: Share tank data with homeowners, tenants, or facility staff.
- Multi-liquid compatibility: Suitable for heating oil, water, AdBlue, and other compatible liquids (and some solids).
- Weatherproof & durable: IP68-rated sealed ABS enclosure for outdoor, bunded, or underground tanks.
