How to calibrate radar level meter? What are the proper calibration procedures and frequency?
Complete guide to radar level meter calibration including zero point, full scale, and distance calibration procedures with 6-month intervals
Radar level meter calibration is essential for maintaining measurement accuracy in water monitoring applications. Ecolor Technology's FMCW radar level meters feature advanced calibration algorithms with multiple calibration methods:
- Zero point calibration: Set current actual water level as reference point using device panel or PC software at known water height
- Full scale calibration: Perform two-point calibration at high and low water levels within measurement range to improve linearity
- Distance calibration: Verify radar ranging accuracy using standard measuring tools like steel rulers, adjust distance compensation parameters
- Environmental calibration: Adjust dielectric constant and propagation velocity based on site temperature, humidity conditions
Recommend routine calibration every 6 months, immediate recalibration after extreme weather or equipment relocation. Compatible with EC32/EC60 RTU series for remote calibration and parameter adjustment capabilities.
