    Applications:

     

     

    LS20B type propeller flowmeter is a kind of large range hydrological flowmeter, which is 

    applicable to measure high, medium, and low flow rate of rivers, lakes, channels, reservoirs 

    and so on. It can also be used for measuring high speed or ultrahigh speed flow rate in 

    pressure pipe of power station and some scientific experiment. 

     

     

    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 waterpower. 

    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 

    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.

     

     

    Special remind:

     

    Every time, the charging time should not be more than 5 hours.

    Please recharge the battery after it uses up.
