LS1206B Type Propeller Current Meter

1. Product Introduction

The LS1206B Type Propeller Current Meter is a conventional general-purpose instrument used for flow velocity measurement in hydrological tests. It is employed to measure the time-averaged flow velocity at predetermined points in cross-sections of rivers, lakes, reservoirs, canals, and other water bodies. It can also be used for flow velocity measurement in pressure pipelines and certain scientific experiments. This instrument is widely used for flow measurement in small irrigation channels. Due to its excellent dynamic sealing performance of the rotating shaft, it can still operate normally in irrigation districts using Yellow River water, where the sediment concentration reaches 20 kg/m³.

2. Product Features

Compact size and lightweight design; sturdy and precise structure; easy to carry and use.

3. Main Technical Specifications

1) Propeller rotation diameter: Φ60 mm

2) Propeller hydraulic pitch: H = 120 mm

3) Starting flow velocity: V0 ≤ 0.06 m/s (standard product)

4) Flow velocity measurement range: 0.07–7 m/s (standard product)

5) Operating water depth: 0.1–1.2 m (measuring rod)

6) Calibration accuracy: Formula mean square error m ≤ ±1.2% (standard product)
