Description:

 

LS1206B portable velocity flow meter (Portable velocity apparatus) is an equipment used in 

water conservancy for velocity flow measurement, designed for hydrological stations, mining 

factories,  environmental monitoring stations, farm irrigation, hydrogeology and so on.

Portable velocity flow meter is composed of spin paddle velocity sensor ( or other type spin 

cup and screw propeller velocity apparatus), HT type velocity flow meter and 0.4 m x 4  16 

measuring bar. Full set of instruments are in the aluminum-alloy password boxes. When using, 

you can assemble it as a body and connect the signal line, then the velocity of every open channel 

can be measured. And it can automatically display the velocity and preset the flow of sectional areas.

 

 

 

 

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 alculated.

 

 

 

 

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.
