Non-Intrusive Level Sensor

The TL400-I is a non-intrusive level and volume sensor that is ideal for detect liquids, grains, fluids and bulk solids in static or moving applications. With a low-power laser beam, it performs several measurements per second while an advanced algorithm calculates not only the exact level, but also convert to volume and distance in several units.


It can be parameterized by a configurator app via Bluetooth. With this feature is possible to save customized points and get accurate measurement even in irregular tanks.
