LS25-3A Type Propeller Current Meter

1. Product Introduction

The LS25-3A type is a large-range current meter. Some technical specifications of the LS25-3A propeller current meter are superior to those of the LS25-1 type propeller current meter. It features a wide measuring range, suitable for high, medium, and low velocities. It is used for high-speed measurements in river channels, pressure pipelines of hydropower stations, spillways, and high-speed closure measurements in dam projects, as well as medium and low-speed measurements in reservoirs, lakes, and general rivers. The LS25-3A current meter has a compact structure, flexible rotation, and excellent waterproof and sand-resistant performance.
