SLDLF2510‑2M‑1000H Acoustic Doppler Current Profiler (ADCP)
SLDLF2510‑2M‑1000H Acoustic Doppler Current Profiler (ADCP) Mainly used for flow velocity and discharge measurement in river channels up to 35 m in width.
Product Characteristics
‑ Easy‑to‑operate current profiler, capable of acquiring velocity profile, water‑level and other data parameters.
‑ Powerful digital signal‑processing technology; velocity profile supports up to 256 measurement bins.
‑ Simultaneously measures vector angles of layered flow velocity and outputs forward / reverse flow direction.
‑ Built‑in underwater ultrasonic water‑level sensor and static pressure water‑level sensor; external water‑level sensor is also supported.
‑ Communication interfaces: RS485 (standard Modbus protocol), SDI‑12, RS‑232, RS‑422.
‑ Supports input of field parameters and irregular cross‑section diagrams for calculating water‑cross‑section area and flow discharge.
‑ Integrated attitude sensor for easy installation with minimal civil‑engineering work.
‑ Anti‑theft function: built‑in GPS+4G communication module. When the device is powered off or displaced, position information will be automatically sent to pre‑configured mobile‑phone clients for device recovery.
‑ Low‑power‑consumption design for long‑term field deployment.
‑ User‑friendly configuration, diagnosis and commissioning software.
‑ Military‑grade high‑temperature‑resistant chips adopted.
