The Helix Flow is a non-contact ultrasonic tank level monitor built for vans, RVs, and expedition vehicles. Top-mounted and maintenance-light, it replaces float sensors, sticky probes, and guesswork with precise readings for water and compatible oils—so you always know your true capacity on the road.

Designed for the Helix ecosystem, Flow works locally (cloud-free) and pairs via Bluetooth with the Helix app for live percentages, history, and configurable high/low alerts. Its wide 10 cm–2.9 m detection range, rugged housing, and anti-vibration design make it ideal for real off-grid use and builder installs. Integrates cleanly alongside Helix Pulse and other Helix devices for a single, unified dashboard.

Whether you’re managing a full water system or just want smarter monitoring, Helix Flow puts accurate tank data at your fingertips—reliably, intelligently, and without touching the liquid.

Note: Not intended for gasoline, diesel, or hazardous/pressurized liquids.
