LS25-1A Type Propeller Current Meter
1.Product Introduction
The LS25-1A Type Propeller Current Meter is an improved instrument based on the LS25-1 Type Propeller Current Meter. It is used to measure the average flow velocity at predetermined points in cross-sections of water bodies such as rivers, channels, reservoirs, and lakes, thereby determining the flow rate of the cross-section.
2.Main Technical Specifications
1. Velocity measurement range: v=0.06～5.0 m/s
2. Starting velocity of the instrument: V0≤0.05 m/s
3. Critical velocity of the instrument: ≤0.12 m/s
4. Mean square error of the calibration formula: ∣m∣≤1.5%
5. Rotational diameter of the propeller: ф=120 mm
6. Hydraulic pitch of the propeller: 250 mm
7. Number of propeller rotations between two signals: 1 rotation
8. Working water depth: 0.2≤H≤24 m
9. Cumulative continuous working time: 8 h
