Step 7: At this point, wait for the PhoenixSuit interface to pop up. You can release the one-button recovery button and press OK to start the flashing.
Step 8: After the success of the brushing, unplug the USB cable, and then connect the player and the TV according to the normal method.


4, SD card burning upgrade

The first step: first download the latest firmware of Mele M9 to the computer, after decompression there is an M9_V3.1.2_20131204.img file;

The second step: download the Brush Toolkit, decompress and run PhoenixCard.exe software;

Step 3: Use a card reader to connect the sd card to the computer (need to ensure that there is only one external storage device at this time, otherwise the application does not know which device to burn);


Step 4: Click the image file (button) and select the firmware you want to flash

);


Step 5: Click to flash (Note: The sd card will be formatted during the programming process. If there are important files on the sd card, please backup);


Step 6: When the progress bar is completed and the programming is finished, click Exit (button), and then pull out the sd card.


Here, the sd card is burned and can be used repeatedly.

The following is the use of burned sd card, upgrade the box:

1) In case of power failure, insert the sd card into the sd card slot of the box;
2) When the power is on, when the indicator light on the box begins to flash, it indicates that the programming is started;
3) When the indicator light stops flashing, the programming is completed, and the sd card and the power supply are pulled out (Note: If the sd card is not removed, the power supply will continue to be written again when the power is turned off);

Piezoelectric ceramic disc   

Quick delivery 

High performance

Application: flow meter measurement 


There are many kinds of USF used in closed pipeline according to the measuring principle, and the most commonly used are propagation time method and Doppler method. Among them, time difference ultrasonic flowmeter is used to measure fluid flow by the principle that the time difference of sound wave propagating downstream and countercurrent is proportional to the velocity of fluid flow. It is widely used in raw water measurement of rivers, rivers and reservoirs, process flow detection of petrochemical products, water consumption measurement of production process and other fields. According to practical application, time-difference ultrasonic flowmeter can be divided into portable time-difference ultrasonic flowmeter, fixed time-difference ultrasonic flowmeter and time-difference gas ultrasonic flowmeter.


Ultrasonic flow-meters use at least two transducers aligned so that ultrasonic pulses travel across the flow of liquid or gas in a pipe at a known angle to the flow.
