Ultrasonic Gas Flow and Oxygen Sensor - 2

What’s ultrasonic? Ultrasonic is the frequency above 20,000 Hz of sound waves, it is a good direction, penetrating ability, and easy to obtain a higher concentration of sound energy, across far distance in water, can be used for distance, speed, cleaning, welding, gravel, Sterilization and so on. It has many applications in medical, military, industrial, agriculture ect. Theory of ultrasonic flow and concentration : in the pipeline full of fluid, the ultrasonic pulse transmitted by the fluid , the downstream direction and counter-current direction have different travel time, different gas...

Ultrasonic Gas Flow and Oxygen Sensor - 10

◆Power Supply Interface J5: Voltage of 12V, ◆ Linear output interface J1: Output voltage 0 ~ 5V, with the flow and O2 corresponding linear measurements. When the voltage is 0V, the output to 0; when the voltage is 5V, the corresponding output is full scale. ◆ Serial Interface J2: is the TTL level, not directly connected with the calculation serial port. If the connection with the computer, you need to take special serial converter (TTL switch to RS232). Serial can read the measurements by the sensor and maintenance the sensor. Oxygen monitor interface shows LCD display DC12V power supply to...
