AS 3778.6.4:2022 identically adopts ISO 4366:2007, which provides information concerning the principles of operation, selection and performance criteria for echo sounders used in depth measurements for open-channel flow (and related) measurements. The use of standard terminology is promoted.

This International Standard provides information concerning the principles of operation, selection and performance criteria for echo sounders used in depth measurements for open-channel flow (and related) measurements. The use of standard terminology is promoted.

The state-of-the-art of echo sounders is well advanced, and sounders have been put into widespread use for many different applications. Consequently, a variety of specialized echo sounders have evolved to best meet the specific requirements of the application. A digital echo sounder with an integrated analog chart generated by a thermal or inkjet print head is the most common echo sounder used for openchannel applications. Multiple-transducer systems are in common use by many professional surveyors and the use of single-transducer, multibeam-swath systems is expanding rapidly.
