Parameter setting

The method of modifying K value and measuring time T is the same as above. First, you should press the setting key to shift, and the press the setting number key to set number untill getting the correct number. You can repeat the above operation if you press the wrong key.

3.1.1 In display screen, the symbols between K and C show the signal period delay time:

"0" is the shortest fixed delay (20 B and 1206 B can only use this file)

"1" is 1 second delay;

"2" is 2 seconds delay;

"3" is 3 seconds delay;

"4" is 4 seconds delay;

Note: The tongue reed pipe signal of 20, 12, 10A type is not required to set delay.

Competitive Advantage:

1) Especially extensive speed measurement range, one propeller can satisfy different 

measurement requirements.

2) Fine sealing performance makes regular work in operational condition of high 

speed and high sediment concentration possible. (Highest measurement speed: 4.3m/s, 

highest sediment concentration 100kg/m³)

3) The propeller adopts imported high quality engineering plastics,which is of high impulse 

strength, stable geometry,and aging resistance. The docimasy coefficient K won't change 

in harsh natural condition environment.

4) Low-speed performance—internal friction characteristic.

5) Flexible installment manner and reasonable directional device structure can adapt 

direction of current.

6) Fine structure intensity makes installment and support firm and can stand 15m/s high 

flow rate impact.

7) Streamline overall and built-in type empennage counter weight reduces water resistance.

No additional deflection moment.
