1. Product Introduction
The Acoustic Doppler Current Profiler (ADCP) measures water flow velocity based on the acoustic Doppler effect. Its transducer emits pulses of a fixed frequency. When these pulses hit suspended particles and other scatterers in the water, echo signals are generated and received by the ADCP. Suspended particles drift along with the water flow, which creates the Doppler effect — a frequency shift between the transmitted signal and the received echo. The flow velocity at each measuring point is calculated by measuring this Doppler frequency shift.
2. Application Scenarios
Flow velocity measurement for rivers, reservoir sluices, underground sewer pipe networks, irrigation channels, etc.; Auxiliary water treatment monitoring, including urban water supply and sewage discharge monitoring for sponge cities; Flow metering and inflow/outflow volume monitoring.
3. Product Advantages & Features
◆ Multi-layer velocity profiler with low power consumption and automatic calibration
◆ Layered flow velocity measurement, well-suited for flow distribution monitoring in wide watersheds
◆ Supports web cloud data service; built-in water depth measuring probe is optional
◆ Equipped with built-in temperature sensor for automatic sound velocity calibration; integrated attitude sensor and water level sensor for synchronous measurement
◆ Two working modes available: command-triggered sampling and interval periodic sampling
◆ Data output: real-time water level, cell velocity, forward/reverse flow status, cross-sectional area, instantaneous flow rate, cumulative water volume and other parameters
◆ Adopts standard Modbus communication protocol, compatible with most domestic and foreign RTUs
◆ Expandable water level measurement modules: ultrasonic and ceramic pressure sensors can be integrated, and radar level sensor can be externally connected; reinforced POM housing enables simple installation
