The WSR100-E radar level transmitter operates based on the FMCW radar measurement principle.
The radar emits a continuously modulated electromagnetic wave toward the liquid surface. When the wave encounters the medium, it is reflected back and received by the radar antenna. The distance R between the radar installation point and the liquid surface is proportional to the frequency difference Δf between the transmitted and received signals:
R = C × Δf / (2 × K)
Where:
Since C and K are known constants, the distance R can be accurately calculated. By subtracting the measured air distance from the known installation height, the actual liquid level is obtained.
The WSR100-E radar level transmitter is specially designed for open water and outdoor level measurement applications, including but not limited to:
River water level monitoring
Continuous and accurate level measurement for flood control and hydrological analysis.
Lakes and reservoirs
Long-term monitoring of water storage and seasonal level variations.
Shoals and wetlands
Reliable measurement in shallow water environments with changing surfaces.
Flood early warning systems
High stability and fast response for real-time water level monitoring.
Hydrological and environmental monitoring stations
Ideal for unattended measurement in remote or harsh outdoor conditions.
Open channels and irrigation systems
Accurate level measurement for water management and distribution.
