FX200
Product Description
The Geolux FX200 is an integrated instrument utilizing advanced
FMCW 4D surface velocity radar and FMCW water level radar
meter, and a LiDAR-based river channel scanner. Designed for
non-contact measurement applications, the FX200 enables rapid
deployment above water surfaces while minimizing maintenance
requirements.
The FX200 is based on the advanced 4D radar processing that
delivers superior performance compared to conventional Doppler
based surface velocity radars. While traditional Doppler sensors
are susceptible to measurement degradation from ambient
interference, precipitation, and structural vibration, the FX200’s
signal processing architecture ensures consistent, high-accuracy
velocity measurements under all environmental conditions.
Calculation of the total flow discharge is internally implemented
within the instrument by combining surface velocity measurement,
water level measurement, and a the configured cross-section of
the river or channel. The cross-section of the river or channel can
be automatically determined and updated by an on-board LiDAR
scanner, eliminating the need for manual measurements of the
channel cross-section.
