The ChannelMaster type horizontal acoustic Doppler current profiler (referred to as CM type H-ADCP) is a new generation ADCP product from RDI company. It has a compact structure, high standard configuration, strong functionality, and a wide range of applications.

The main features of ChannelMaster type H-ADCP are:

Adopting RDI's broadband patented technology.
High precision, high spatial and temporal resolution. Smaller units can be used
Obtain accurate flow velocity data within a shorter sampling time step.
High quality test data can also be obtained for low flow rates and unsteady flows that are difficult to test.
Standard configuration: 1-128 optional units, 0.1-10 m optional unit length, 1
-300 m profile range (depending on system frequency). You can get more
Flow rate data has great flexibility.
Standard configuration includes ultrasonic water level gauge and pressure type water level gauge.
• Standard configuration inclinometer. Tiltmeter for adjusting H-ADCP installation bracket and monitoring
The tilt variation of the installation bracket plays an important role in ensuring the quality of test data.
Standard stainless steel mounting base makes H-ADCP installation very convenient.
Throughout its more than 20 years of development, RDI has always been at the forefront of ADCP technology
Leading position. RDI company has passed ISO9001 international quality system certification.

Application of H-ADCP:

Real time measurement of flow velocity and flow rate at river hydrological or hydrological stations (using indicator flow rate method or numerical method to calculate flow rate)
Real time measurement of open channel flow velocity and flow rate
Real time measurement of irrigation channel flow velocity and flow rate
Real time monitoring of the total amount of river water quality monitoring stations
Collect flow field data in river and estuary areas to provide calibration or validation data for flow field numerical models.
Real time monitoring of the flow field in port waters provides flow velocity data to ensure the safety of incoming and outgoing ships.
Real time monitoring of flow field near offshore oil platforms
