Working Principle

Based on the physical transmission characteristics of ultrasound, oxygen concentration and flow rate are calculated by detecting the upstream and downstream transit times. As shown in the figure, oxygen enters the ultrasonic oxygen sensor through the inlet, flows from the transceiver ultrasonic probe 1 to the transceiver ultrasonic probe 2, and then exits the sensor through the outlet. The forward transit time is the duration required for a signal transmitted from the transceiver ultrasonic probe 1 to reach the transceiver ultrasonic probe 2. The reverse transit time is the duration required for a signal transmitted from the transceiver ultrasonic probe 2 to reach the transceiver ultrasonic probe 1.

Interface Wiring Method

The ultrasonic oxygen sensor employs serial port communication, with the interface as shown. The power supply voltage input port in the table is for production use only and should not be utilized by users. The digital signal output port in the table serves as the user interface for transmitting and receiving data upon power-up.
