    that the compact 80 GHz radars from KROHNE can be easily commissioned and monitored via Bluetooth ® ? Operators can make the settings themselves using the OPTICHECK Level Mobile app – without any prior knowledge and using just a few parameters. The app also allows easy access to the OPTICHECK technology built-in diagnostics and therefore fast device verification, including reporting.
