ChannelMaster ADCP

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 Teledyne RDI’s BroadBand technology, 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. The standard unit comes equipped with temperature, pressure, pitch and roll sensors, and a vertical beam Key Features: Accurate: Teledyne RDI Broadband technology allows for small cells and/or short averaging sampling intervals, thus increasing your data accuracy Robust: Collect highly accurate velocities even in difficult environments such as slow flow or rapidly changing flow Versatile: ChannelMaster offers a range of 1-128 user selectable cell sizes from 25 cm - 8m and profiling ranges from 1m - 300m (frequency dependent) Sturdy: Comes standard with stainless steel mounting fixture.
