VX60

High-precision Non-contact Open Channel Flow Meter

The Geolux VX60 is a high-performance radar sensor utilizing advanced FMCW 4D radar technology to provide measurement of the surface flow velocity. Designed for non-contact measurement applications, the VX60 enables rapid deployment above water surfaces while minimizing maintenance requirements.

The VX60 employs advanced 4D radar processing that delivers superior performance compared to conventional Dopplerbased surface velocity radars. While traditional Doppler sensors are susceptible to measurement degradation from ambient interference, precipitation, and structural vibration, the VX60’s signal processing architecture ensures consistent, high-accuracy velocity measurements under all environmental conditions.

The radar operates in V-band (60 GHz) and provides flow speed readings over serial RS-232, RS-485 Modbus and SDI-12 interfaces. The instrument is compatible both with Geolux and 3rd part dataloggers. An integrated MEMS sensor provides the data for automatic tilt angle compensation.
