LS25-1A rotary propeller flowmeter

The LS25-1A propeller flowmeter is an improved instrument based on the LS25-1 propeller flowmeter, used to measure the average flow velocity at predetermined measurement points in general rivers, channels, reservoirs, lakes, and other cross-sections, in order to determine the flow rate of the cross-section.
