● Overview
Wireless (wired) hydrological flow velocity measuring instrument：

1. Upgrade the display to a large character Chinese character LCD display with background light, which is convenient for operators to use all day long.
2. Upgraded the original wired signal acquisition to a combination of wired and wireless, expanding the scope of use of the instrument.
3. Equipped with flow velocity storage function, it can store the flow velocity of 100 cross-sectional points and query the flow velocity of cross-sectional points at any time.
4. There is an RS232 interface that can communicate with the computer in real-time and transfer stored data to the computer.
