Solution to the problem of inaccurate measurement of radar level meter

The inaccurate measurement of radar level meter may be caused by many reasons. The following are some common reasons and their solutions:
1. Improper installation position
Cause: The radar level meter is installed near the tank wall, agitator, feed port, etc., resulting in signal reflection interference.
Solution: Adjust the installation position to keep it away from obstacles and interference sources, and ensure that the radar beam can irradiate vertically to the surface of the measured medium.
2. Signal interference
Cause: There is strong electromagnetic field interference or noise signal interference generated by other electronic equipment around.
Solution: Try to stay away from strong electromagnetic field environment, increase shielding measures or change the working frequency if necessary.
3. Changes in medium characteristics
Cause: The dielectric constant, temperature, pressure, viscosity and other characteristics of the measured medium change, affecting the propagation and reflection of radar waves.
Solution: Calibrate the radar level meter, enter new medium parameters, or select a radar level meter suitable for different medium characteristics.
4. Antenna pollution or damage
Cause: The antenna of the radar level meter is polluted by dust, dirt, scaling, etc., or the antenna is damaged.
Solution: Clean the antenna regularly to keep its surface clean. If the antenna is damaged, it needs to be replaced.
5. Waveguide problem
Cause: If a waveguide is used for measurement, there is scaling or obstacles on the inner wall of the waveguide, resulting in signal attenuation or poor reflection.
Solution: Check and clean the waveguide regularly to ensure that the inner wall is smooth and free of obstacles.
6. Incorrect installation angle
Cause: The radar level meter is not installed vertically, resulting in measurement angle deviation.
Solution: Adjust the installation angle of the radar level meter so that it is perpendicular to the surface of the measured medium.
7. Equipment failure or parameter setting error
Cause: The radar level meter itself fails, or the parameters are improperly set (such as range, blind area, etc.).
Solution: Check the working status of the equipment, perform fault diagnosis, reset or calibrate the parameters, and contact the manufacturer's technical support if necessary.
8. Multipath reflection
Cause: Complex tank structure or uneven surface of the medium causes multipath reflection of radar waves, affecting measurement accuracy.
Solution: Optimize the installation position and angle, and use a radar level meter with signal processing function to reduce the impact of multipath reflection.
By carefully checking the above possible reasons and taking corresponding solutions, the problem of inaccurate measurement of radar level meter can be effectively solved to ensure its measurement accuracy and reliability.
