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
