Level meter used for Sewage monitoring in sewage treatment plants.
Ultrasonic level instruments operate on the basic principle of using sound waves to determine liquid/ solid/slurries level. In addition to standard level or volume measurement, they can monitor open channel flow, determine the actual volumetric throughput in lift stations, measure differential level and control the pumps.

4. How to choose A-ULM Ultrasonic Level Meter?
The measurement range will be different in different environment, such as temperature, humidity, and other objectives
Following tables are for reference while choosing the right measure range:
|Liquid Surface||Decay Rates||Percentage of Decay||The value of Respected Measure Range|
|Smooth & Stable||0dB||0%||Equal to the Measurement Range|
|Corrugated||5...10dB||50～67%||1 times of the Measurement Range|
|Large fluctuations (such as mixing blades)||10...20dB||90%||3 times of the Measurement Range|
|Solid Object Surface||Decay Rates||Percentage of decay||The value of Respected Measure Range|
|Hard, rough (such as the granulated rubber)||40dB||99%||10 times of the Measurement Range|
|Soft(such as coal, cement, fly ash)||40...60dB||99～99.9%||Not recommended|
