Used under certain operating conditionsShanghai YichuanThe radar level gauge has encountered some problems due to improper installation position and conditions of the sensor. Below are some solutions to the problems encountered during use for your reference.
The first solution to the problem of probe scarring and frequent malfunctions is to raise the installation position of the probe. However, sometimes the installation conditions are limited and cannot be raised. Therefore, the method of interlocking the measured material level with the pump of the tank should be adopted to solve this problem: reduce the highest material level setting value by about 0.5m. When the material level reaches the highest value, the feed pump can be stopped or the discharge pump can be turned on.
2. The influence of foam on measurement:
Dry foam and wet foam can reflect back the radar wave and have no impact on the measurement; The neutral foam will absorb and diffuse the radar wave, thus seriously affecting the reflection of the echo or even no echo. When the medium surface is thick and thick foam, the measurement error is large or cannot be measured. Under this condition, the radar level meter has no advantage, which is the limitation of its application.
3. Treatment of antenna scars:
Materials with low dielectric constant have no effect on the measurement in a dry state, while materials with high dielectric constant have an impact on the measurement. Compressed air can be used for blowing (or rinsing with clean water), and the cooled compressed air can lower the temperature of flanges and electrical components. Acidic cleaning solution can also be used to clean alkaline scars, but material level measurement cannot be performed during the cleaning period.
