10 Wading Rod (additional): 

CG16-1 wading rod for open channel: 1600 mm in four sections;

Inner supporting type special wading rod for pipeline



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:        


                 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

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.
