    200mm LS20B Propeller Type Current Meter For Velocity Measurement

     

    Measuring principles:

    This instrument is designed based on the theory of areas of open channel’s velocity.After measuring the velocity, the flow can be get:Q=V·S(S is sectional area)

    • Velocity measurement

    When measuring velocity, the spin paddle type rotor flow meter will be pushed by water ower. The built-in signal apparatus produces RPM signal. The formula below can calculate velocity:

    (K/b)N

    V=—————- + C/a(m/s)

    T

    V: the average velocity (m/s)

    B/K:the waterpower pitch of blades

    a/C: velocity constant

    T: lasting time(the unit is s)

    N: the number of signals in T time

    S: sectional area

    Q: flow

    K/b, C/a are constants

    When measuring, you can setT and then measure N, so the velocity and flow can be automatically calculated.

     

    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.

     

    Life Span

    1. 5years under correct operation and maintenance.

    • Under correct operation, calibration formula should be checked after 1—2years.

     

    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.
