Discharge Measurement with ChannelMaster H-ADCP
In the last several years, H-ADCP's have become common in a variety of applications such as discharge measurements in rivers and streams or open channels.
The compact, flexible, and affordable ChannelMaster is a horizontally-oriented Acoustic Doppler Current Profiler (H-ADCP) designed to collect high-accuracy water velocity, stage, and discharge data for a wide array of applications.
By leveraging a patented BroadBand technology, the ChannelMaster allows you to obtain unmatched data quality, even in low velocities and complex flows, where a single cell cannot provide enough information. The ChannelMaster's innovative design includes everything you need to collect high-quality data, without costly options. The standard unit comes equipped with sensors for temperature, water level and pitch and roll -as well as mounting fixture.
ADCP sensors: 300kHz, 600 kHz or 1200 kHz
ChannelMaster Highlights:
- BroadBand technology, which allows small cells and/or short averaging/sampling intervals, resulting in highly accurate velocity data
- Ability to measure highly accurate velocities even in difficult environments such as slow flow or rapidly changing flow
- A range of 1–128 user-selectable cells, with cell sizes from 25cm to 8m
- Profiling ranges from 1m to 300m (depending on system frequency)
- Standard stainless steel mounting fixture
Applications
Rivers, streams, and waterways:
Obtain high-accuracy data for monitoring velocity, stage, and discharge data.
Estuaries:
Measure complex currents for environmental monitoring or circulation model calibrations.
Ports and Harbors:
Monitor currents to provide accurate information for vessel maneuvering and safety
with protection against swimming items (algae, wood etc.)

Data Registration an Data Processing with Q-Eye H-ADCP
The Q-Eye H-ADCP is a flexible, compact and fully configurable PC-system. It is used to display real time data of ChannelMaster H-ADCP (CM300, CM600, CM1200) and of Workhorse H-ADCP (long range) as well as to calculate flow and to store data. The device includes interfacing for remote data transmission (analogue/ISDN, GSM/GPRS). The Q-Eye H-ADCP is the ideal system for discharge monitoring in rivers and streams or artificial channels using H-ADCP technology.

Software FlowVision
FlowVision sets new standards for ultrasonic measurement systems. The user-friendly, windows-based and multi-language software (English, French, Spanish, Italian, German) provides numerous functions. Main tasks are to control and to parameterize the measurement system as well as to process and to store data. The sample rate for data logging can vary from once a minute to once an hour in desired units of measure. All parameters (cross section, cell size, number of cells, blanking etc.) are easily configurable to your specific application. The calibration (numerical calibration, ISO 6416) and integration algorithms give superior flow calculation. The benefits are reduced start-up time configuring of the ChannelMaster, comprehensive instrument health diagnostics and reduced field technician costs with remote communications.
