AOUCM77 Ultrasonic Concentration (Solid Content) Meter

The product first uses a sensor to emit an ultrasonic signal. After the signal penetrates the medium being measured, it is captured by a receiving transducer. The system then analyzes the changes in the energy of the received signal and, combined with a built-in database matrix, performs data processing to ultimately determine the concentration of the medium, thereby enabling accurate measurement of the medium’s concentration. However, since bubbles in the medium can significantly interfere with the ultrasonic measurement, this measurement method cannot be used under conditions where such bubbles are present.

- AOUCM77 Ultrasonic Concentration (Solid Content) Meter
◆ Measurement principle
The product first uses a sensor to emit an ultrasonic signal. After the signal penetrates the medium being measured, it is captured by a receiving transducer. The system then analyzes the changes in the energy of the received signal and combines this analysis with a built-in database matrix to perform data calculations, ultimately reconstructing the concentration of the medium and achieving accurate measurement of its concentration. However, since bubbles in the medium can significantly interfere with the effectiveness of ultrasonic measurements, this measurement method cannot be used under conditions where such bubbles are present.

◆ Main features
▶ Measurement parameters: Concentration (unit: % or g/L);
▶ The medium particles are uniform and free of bubbles.
▶ Structure: Split-type industrial aluminum housing;
▶ Backlit full-Chinese LCD display;
▶ Three major display interfaces: concentration, waveform, and raw received ultrasonic signal values;
▶ Return wave curve display interface;
▶ 8-speed adaptive gain circuit;
▶ Fast-response digital filtering algorithm;
▶ Supports secondary calibration from 1 to 9 points on-site;
▶ 4-key operation menu;
▶ Optional built-in wireless modules: 4G, NB-IoT, LoRa;
▶ Awards: Multiple patents and software copyrights

◆ Application scenarios
▶ [Concrete Production]: Concentration (solids content) of the slurry in the wastewater tank used for cleaning and recycling the mixing drum (for both process and transportation);
▶ [Water Treatment]: Sludge concentrations in various stages of water treatment plants and wastewater treatment plants, including return sludge from water plants, primary sedimentation tanks, secondary sedimentation tanks, thickening tanks, and sludge dewatering processes;
▶ [Industrial Production]: Concentrations of slurry, coal slurry, ash slurry, and pulp in coal preparation plants, mines, paper mills, and power plants.
