LinkQuest is to exhibit the FlowQuest acoustic current profilers and NavQuest Doppler velocity logs. Also in booth H10 will be the newly released small, light-weight FlowQuest 2000 acoustic current profiler which operates at 2 MHz with a blank distance as short as 10cm.
The FlowQuest 2000 acoustic current profiler is ideal for measuring currents, flows and discharge in shallow waters.
Members of the US Geological Survey were filmed while out on the Missouri River at Williston, North Dakota, USA, performing a hydrographic survey to monitor the state of riverbed erosion. They were using a multibeam echo sounder which transmits sound energy and analyses the return signal (echo) that has bounced off the riverbed or other objects. Multibeam sonars emit sound waves from directly beneath a ship's hull to produce fan-shaped coverage of the riverbed.
