2 The Hydraulic Thread Pitch for Propeller: H=120mm
3 Minimum Velocity: Vo≤0.06m/s(Normal)
4 Measuring Range: 0.07～7m/s(Normal)
5 Operational Depth: 0.1～1.2m(Wading rod)
6 Accuracy:unbiased variance: m≤±1.2%(Normal)
7 Signal: two signals on every rotary
8 Operational Condition:0～35℃
9 Continuous Running Time:24h
10 Wading Rod (additional):
CG16-1 wading rod for open channel: 1600 mm in four sections;
Inner supporting type special wading rod for pipeline
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
