    Did you know ...

    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.

    Find out how a wastewater treatment plant operator uses the cost-effective 80 GHz radars to monitor its flocculant inventory. Commissioning was carried out wirelessly at a safe distance from the chemical tank.
