LEVELWATCH for iOS
Levelwatch software uses external wireless sensors NAVIS LW BLE-C or NAVIS LW BLE-S to measure level of liquids in tanks/reservoirs.
How to connect sensor with your smartphone?
Each sensor has its own address, which is written on label on the sensor. Navigate to "Settings" and write your sensors address into field or select "Find sensor" for automatic scan.
How to install sensor on tank?
For sensor installation instructions please look at NAVIS LW BLE-C or NAVIS LW BLE-S user manual.

- 4. Tap "Set min" to set a minimum level.
- 5a. LW BLE-C sensor: Dive as much of measuring cable as you want to be indicating full level into water and wait for a minute.
- 5b. LW BLE-S sensor: Fill tank with liquid to the point of max. level and wait for 5 minutes. "Current data" will show you numeric data from sensor.
- 6. Tap "Set max" to set a maximum level.
- 7. With "tank name" you can customize your tank's name (eg. Drinking water, Recycling, Rain...).
- 8. Optional you can set low and or high alarm in percentage, volume units or in numerical data (current data).
