LTR-mini Mini Radar Level Transmitter
80 GHz FMCW non-contact radar — ideal for open channels, water/wastewater, flumes and liquid tanks. ±2 mm accuracy.
LTR-mini is the ideal sensor for non-contact level measurement in simple applications. Particularly suitable for open channel applications: water/wastewater, rain basins, flume, dam level monitoring. Can also be applied on liquid tanks or containers. Uses 80 GHz FMCW technology with ±3.5° beam angle for precise, focused measurement. Bluetooth connectivity and optional display for easy commissioning.
