Scope of application

The LS25-3D model is a large-scale flowmeter used for high-speed measurement of river channels, pressure pipelines, spillways, dam engineering closures, as well as medium and low-speed measurement of reservoirs, lakes, and general rivers. The LS25-3D flowmeter has a compact structure, flexible rotation, and excellent waterproof and sand proof performance.
