Non-Intrusive Level Sensor

The TL400-I is an advanced level and volume sensor with a non-intrusive approach, making it well-suited to detect liquids, grains, fluids, and bulk solids in static and moving applications. Employing a low-power laser beam, the device performs multiple measurements per second, and an advanced algorithm calculates the precise level and converts it to volume and distance in various units.


The device can be easily customized with a configurator app via Bluetooth, allowing users to save customized points and obtain accurate measurements even in irregular tanks. Its superior performance and user-friendliness make it an excellent choice for various industrial applications.
