HS-2 type flow meterDetailed product description：

HS-2 type is a large range flowmeter used for high-speed measurement of river channels, pressure pipelines of hydropower stations, spillways, dam engineering closures, as well as medium and low-speed measurement of reservoirs, lakes, and general rivers. The HS-2 flowmeter has a compact structure, flexible rotation, and excellent waterproof and sand proof performance.

Instrument Features
The HS-2 flowmeter is a significant improvement over the LS35-5C. Redesigning the Mystery Palace, the bearing chamber can store lubricating oil for a long time, and the waterproof and sand proof performance has been greatly increased, requiring no disassembly, cleaning, or maintenance for a long time. The structural design of the instrument is reasonable, and even during disassembly, cleaning, and maintenance, as long as the assembly sequence of the parts is correct, it can basically work without adjustment. This instrument uses a miniature reed switch imported from the United States, which has a high frequency and long lifespan during use. It is equipped with a device for one signal per rotation or two signals per rotation, which users can choose from. The signal can be received using a measuring instrument (main supporting instrument) and a Type 4 counter. When the flow rate is less than 6 meters per second, a universal measuring instrument can be used, and when the flow rate is lower, an audio device can be used
