About this app

RadarLink is a companion app for radar and ultrasonic water-level and flow-measurement sensors. Connect to your compatible device over Bluetooth to view live readings, visualize echo curves, and configure your instrument — right from your phone.

KEY FEATURES
• Bluetooth (BLE) connection to compatible water-level and flow sensors
• Real-time measurements: level, air gap (empty height), fill percentage, output current (mA), temperature, and flow rate
• Echo curve view to inspect the raw measurement signal
• On-device configuration: basic settings, display options, advanced parameters, and manufacturer information
• Support for multiple instrument types, including level meters, flow meters, and flow-velocity meters
• Clean, easy-to-read interface with English and Chinese language support

TRY IT WITHOUT HARDWARE
No sensor connected yet? Tap "Demo Device" on the Bluetooth Search screen to load a virtual instrument with sample data, so you can explore every screen and setting before pairing real hardware.

HOW IT WORKS
1. Open the app and choose your meter type.
2. Search for and connect to your nearby Bluetooth sensor.
3. View live measurements and adjust device settings as needed.

PERMISSIONS
• Bluetooth & Location: required by Android to discover and connect to nearby Bluetooth devices. Location is used only for Bluetooth scanning and is never collected or shared.
• Camera: used to scan a QR/barcode when pairing a device.

PRIVACY
RadarLink works locally with your hardware. It does not require an account, and your measurement and configuration data stays on your device.

Note: RadarLink is a companion application. A compatible Bluetooth water-level or flow sensor is required to display live data.
