- Unit selection: mm default; switch to cm or m at any time

Automatic Guide Calibration
- Calibration completed via a 2-step fill and drain sweep after entering tank height
- Automatic distribution of 5-level setpoints based on the measurement range

Multi-Device Management
- Register sensors from multiple tanks in a single app and check connection status at a glance
- Automatic scanning, automatic connection, and automatic reconnection upon disconnection

Level Customization
- Directly set threshold values ​​(L1-L3) for each level
- Easy field identification by changing device names

Demo Mode
- Experience the entire monitoring, calibration, and setting process using simulation data without hardware

Target Users

This is a professional app for engineers and operators who require precise measurement and management of tank liquid levels.
