Is an ultrasonic level gauge suitable for measuring powders?
Thread Content
Ultrasonic level gauges can be used to measure liquid materials; are they suitable for measuring powders as well?
Agree with what was said above; the logic is simple – ultrasonic technology should never be used in dusty environments, while high-frequency radar can be considered as an option.

Ultrasonic level gauges are not suitable for powder silos; even in situations involving solid blocks, their performance is not very good. Nowadays, ultrasonic level gauges are primarily used for liquids at normal temperature and pressure, while other applications are increasingly being replaced by radar sensors. Depending on the type of powder material and the required measurement range, different types of radar level gauges can be chosen. If the budget allows, high-frequency radar level gauges should be considered; if the budget is limited and the measurement range does not exceed 10 meters, cheaper guided-wave radar level gauges can be an option. However, it is necessary to confirm with the manufacturer that such gauges are suitable for the specific medium being measured, for reference only
Not applicable; dust will refract ultrasonic waves. High-frequency radar can be used, as it is effective at penetrating dust.
Ultrasonic level gauges measure based on the signals that are reflected back; they should not be used in situations where the reflectivity is low, or in the presence of materials that absorb sound waves effectively.
Thank you to all the experts for analyzing the issues!
