LS25-1 rotary propeller flowmeter

The LS25-1 rotary propeller flowmeter is a river hydrological measurement instrument mainly used to determine the average velocity of water flow at predetermined measurement points in general rivers, channels, reservoirs, lakes and other water flow sections, in order to determine the flow rate of the section.
