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.

FAQ: Nomadic Controls Helix Flow Tank Ultrasonic Liquid Level Monitor
Will Helix Flow work with my current van or RV setup?
Yes. Flow is a top-mounted, non-contact ultrasonic sensor that works with most fresh/gray water tanks and compatible oils. Choose a flat spot on the tank lid with a clear vertical path to the liquid. It’s best on vented tanks and tanks with minimal foaming. (Not for gasoline, diesel, or hazardous/pressurized liquids.)
How accurate is it—and what affects accuracy?
Flow measures the distance to the liquid surface and converts it to a level based on your tank depth calibration in the Helix app. Accuracy is maximized when the sensor has a clear, unobstructed path to the surface. Heavy foam, slosh near baffles/fillers, or a curved/uneven mounting surface can affect readings. Give the tank a few seconds to settle after driving or filling for the most stable result.
Do I need Wi-Fi or internet for Flow to work?
No. Flow is local and cloud-free. Pair via Bluetooth to the Helix app for live levels, history, and high/low alerts—even when you’re fully off-grid.
Can I monitor more than one tank?
Yes. Use one Flow per tank. The Helix app lets you add multiple devices, name each tank (Fresh, Gray, Aux, etc.), and view them together alongside other Helix gear.
What does installation and maintenance look like?
Installation is straightforward: cut the hole, insert Flow from the top, seal and locknut from below, connect power/data, then calibrate tank depth in the app. Because sensing is non-contact, there’s no probe to foul. Wipe the sensor face if dusty and periodically verify your depth setting if you change tanks or plumbing.
