Description:

LS20B 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 Ф 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.

 

 

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 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 nvironment.

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.
