1. Product Introduction:

Capable of performing horizontal and vertical positioning and distance measurement control for hydrological flow tests, receiving and processing flow measurement signals, and fully automating the recording, calculation, and output of results for river flow tests. The flow test record calculation sheet can be directly printed and stored in a database. The printed result sheet fully complies with regulatory requirements and can be directly used for data compilation.

2. Technical Specifications:

3.Flow Measurement System Configuration:

(1) Wireless signal transmission is adopted. Digital signal transmission is used, with different signals employing different encodings. Various signals are accurately decoded with strong anti-interference capability, eliminating intermittent signal issues.

(2) Effective wireless signal transmission distance: 1000m (in open areas)

(3) No signal cables between the lead fish and the operation room, and no ground wires or antennas from the riverbed to the operation room.

(4) Suitable for one cross-section with two or more current meters, applicable for cross-sections with multiple water flows, and scenarios involving depth measurement without velocity measurement at vertical lines.

(5) Lead fish measurement range: <40m;

(6) Lead fish lifting/lowering speed: 0.35m/s;

(7) Operation methods: wireless remote control or manual operation;

(8) Velocity measurement range: 4m/s; Water depth: -199.00 to 999.99 meters (accurate to 0.01 meters);

(9) Water level setting function for measurement timing: -99.99 to 9999.99 meters

(10) Function to arbitrarily set relative measurement point depth (0.0, 0.2, 0.5, 0.6, 0.8, 1.0)

(11) Function to set single-point velocity measurement duration: arbitrarily set between 1.0 and 9999.9 seconds

(12) Actual single-point velocity measurement duration accuracy: 0.1 seconds

(13) Transmitter battery operating time: 9V stacked battery or rechargeable battery.

(14) Receiver power supply: 220V/50HZ; Optional 12V power supply
