Flexibell — Wireless Water Level Indicator & Alarm System
Wireless Water Level Alarm
Flexibell is Aquabrim's versatile wireless water level indicator and alarm system, built for homes, commercial buildings and institutional sites that want clear visibility into multiple tanks without automating the motor. It receives level data wirelessly from sensors installed in each tank and triggers an alarm the moment a tank runs low, becomes full or overflows.
Each connected tank sends its data wirelessly to Flexibell in the 433 to 434 MHz RF band, removing the need for wiring between tanks and the control unit. Flexibell can display levels for up to 6 water storage tanks, with low, full and overflow alarm thresholds set individually for each tank, and can also show the open or close status of a motorized valve installed near a tank.
Flexibell is highly configurable on site, and can optionally connect to a Building Management System over MODBUS or to Aquabrim's web based monitoring service, which enables SMS alerts to multiple numbers. Level sensors, signal repeaters and the web based monitoring service are sold separately and are not included with the controller unit.

No. Flexibell receives sensor data wirelessly in the 433 to 434 MHz RF band, so no wiring is needed between the tanks and the controller unit.
Yes, as an optional feature. When connected through Aquabrim's web based monitoring service, Flexibell can send SMS alerts for low, full and overflow events to multiple mobile numbers.
Yes, optionally. Flexibell's data can be uploaded to a BMS over the MODBUS protocol, or shared through the optional web based monitoring system, for remote monitoring.
Yes. If a motorized valve is installed near a tank, Flexibell displays its open or close status on the unit.
The Flexibell unit includes the buzzer, display and alarm system. Level sensors, signal repeaters and the web based monitoring service are not included and should be ordered separately based on site requirements.
Yes. Low, full and overflow alarm levels can be set individually for each connected tank, so Flexibell can be configured to match the specific needs of every tank on site.
