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 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.
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)
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:
V＝—————- ＋ C/a(m/s)
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
K/b, C/a are constants
When measuring, you can setT and then measure N, so the velocity and flow can be automatically alculated.
1) Especially extensive speed measurement range, one propeller can satisfy different measurement
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
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
