LS25-1C rotary propeller flowmeter

product overview

The LS25-1C propeller flowmeter is an instrument that improves the labyrinth and signal generation system of the LS25-1 propeller flowmeter. The bearing chamber can store lubricating oil for a long time, thus it has good waterproof and sand resistant performance. The instrument signal is composed of magnetic steel and reed switch, ensuring the quality of the signal, and can be equipped with our company's factory measuring instrument. This instrument is used to measure the average flow velocity at predetermined measurement points in general river, channel, reservoir, lake and other water crossing sections, in order to determine the flow rate of the section.
