Ultrasonic Gas Flow Sensor, 0-10 L/min, 21%~95.6%

The ultrasonic gas flow sensor employs advanced ultrasonic detection principles, specifically designed for oxygen measurement, enabling precise simultaneous detection of flow rate and concentration. The gas flow sensor offers a measurement range of 0–10 L/min and a concentration range of 21%–95.6%. It supports UART (3.3 V) digital output for seamless integration with MCUs, control boards, and host computers. This sensor is ideal for oxygen delivery, analysis, and monitoring systems demanding stringent control accuracy.

Feature

• Utilizing advanced ultrasonic detection principles, it provides non-contact, wear-free measurement of oxygen flow and concentration. This avoids the aging issues of traditional sensors, ensuring higher long-term stability.
• SUCH ultrasonic gas flow sensors support simultaneous detection of flow rates from 0–10 L/min and oxygen concentrations from 21%–95.6%, meeting stringent accuracy requirements in medical, laboratory, and industrial applications.
• Both flow and concentration response times are ≤1.5 seconds (T90), enabling rapid capture of gas changes for real-time monitoring and control.
• The flow sensor operates within a wide voltage range of 4.5–13.2 V, with an average current consumption ≤30 mA. It supports UART (3.3 V) output for seamless system integration.
