  • 4 tank levels + 4 temperatures + 2 line pressures
  • Auto‑calibrates odd‑shaped tanks
  • Freeze and dry‑run pump protection
  • 0.01 W average draw—battery‑invisible
  • Pairs instantly with SmartKnob

Ultra-fast, precise fill-level measurement

Ultra-fast, precise fill-level measurement

Measures the fill level in up to four fresh- or waste-water tanks with pinpoint accuracy—whether standard or wheel-arch tanks.

Easy installation—for all tank shapes

Easy installation—for all tank shapes

Drill a hole in the tank, insert a watertight grommet, place the sensor on the tank bottom—done. Even wheel-arch tanks (usually hard to measure) become highly accurate—no complex calibration or specialist knowledge.

Flexible to customize, freely nameable

Flexible to customize, freely nameable

Name each sensor and tank as you like—everything is clearly displayed on the SmartKnob and in the dashboard.

Smart alarm and warning system

Smart alarm and warning system

Set warnings in the dashboard to your needs—e.g., “too little fresh water,” “too much waste water,” or “leak detected.”

Extended sensing for water comfort

Extended sensing for water comfort

Supports temperature sensors—e.g., for clever energy saving on the boiler or for shower comfort. Optionally monitors water pressure—for maximum protection of your water system.

Real-time leak protection

Real-time leak protection

A dedicated leak alarm system protects you from water damage: in case of a leak, the pump is shut off automatically.

Quick pairing & extremely installation-friendly

Quick pairing & extremely installation-friendly

Connecting to the SmartKnob takes seconds—light and sound confirm it. Sensor leads are plug-in and secure; no tools, no crimping, no stress.

Clear dashboard, no extra app

Clear dashboard, no extra app

All water levels, temperatures & warnings appear automatically on the SmartKnob and in the dashboard—right after connection.

Minimal weight, maximum protection

Minimal weight, maximum protection

FLUIDY weighs only 105 g, runs very energy-efficiently, and is comprehensively tested to EU standards: fully protected against reverse polarity, overvoltage & much more.

Optimal measurement for every tank type—no calibration effort

Optimal measurement for every tank type—no calibration effort

Rectangular tanks: with two entries (height, volume) you’re ready immediately. Wheel-arch tanks: more and more tank profiles are integrated directly; complex calibration is completely unnecessary.

Developed with the community—for van-lifers and pros

Developed with the community—for van-lifers and pros

FLUIDY was born from real exchange with build experts and true van adventurers—your ideas flow in directly.

Future-proof updates

Future-proof updates

FLUIDY stays offline to save energy; updates start automatically via the dashboard—either locally via file or (in future) online (OTA pull with confirmation).

FLUIDY – Technical Feature Overview for Pros

System integration & installation

  1. Mounting weight: 105 g, compact and vibration-resistant for all installation positions in the camper. Removable without tools.
  2. Electrical connection: plug-in spring-clamp terminals for all inputs; enables quick, tool-free connection of sensors and power supply. No crimping required.
  3. Pairing: easy pairing with the SmartKnob. Feedback via LED signal and acoustic tone; status display in the dashboard.

Sensor inputs & measurement functions

  1. Fill-level measurement:
    Supports up to 4 digital, high-precision fill-level sensors (in-house development, not linear resistance sensors).
    Sensor installation: hole (Ø > 10 mm) in the top/side of the tank, feed the sensor through a watertight grommet down to the tank bottom (no gluing or external mounting).
    – For rectangular tanks: entering internal height and volume is sufficient.
    – For wheel-arch tanks: select from tank profiles; the profile library is continuously expanded (no individual calibration needed).
  2. Tanks/modules can be named freely in the dashboard.
  3. Temperature sensors:
    Supports up to 4 waterproof digital temperature sensors (boiler, fresh/waste water tank). Typical range –20 °C to +80 °C, sensor type DS18B20 or compatible; plug-in connections.
  4. Water-pressure sensor:
    Special analog input for external pressure sensors; pump protection via configurable threshold / automatic shutdown of the pump relay.
  5. Leak sensor:
    Digital/switch input for leak-sensor cable. Detects moisture/leaks immediately and triggers visual/acoustic warning and pump-off function.
    Power consumption: < 0.1 W in standby, approx. 0.8 W in normal operation; absolutely silent and maintenance-free.
    Reliable wireless connection to the SmartKnob: stable communication up to 15 m away.

Alarm & monitoring functions

  1. Thresholds/alarms: all limits (fill-level min/max, temperature, pressure, leak) freely configurable in the dashboard.
    Intelligent alerting: acoustic and visual warning on the SmartKnob, dashboard notification, optional push function, pump/relay shutdown in critical states.
  2. Real-time data transmission to the SmartKnob with logging/statistics.
    Intelligent self-diagnostics: automatic notification of communication or connection problems, including self-healing mechanisms.

Safety & standards

  1. Integrated protection against overvoltage, reverse polarity, and temperature.
  2. Self-resetting fuses ensure ongoing operational safety even after faults.
  3. CE-compliant, tested against all relevant EMC and safety standards of current EU directives.
  4. Operating temperature range: –20 °C to +80 °C.
  5. Operating voltage: 9–36 V DC.

Updates & future-proofing

  1. Firmware updates via dashboard:
    – Offline update by file upload (drag & drop)
    – In future, online pull directly from the internet
  2. FLUIDY has no Wi-Fi in normal operation to save energy; Wi-Fi is activated temporarily and automatically for updates and then deactivates itself.
  3. Compatibility with future tank profiles through regular online updates.
