# How Ultrasonic River Gauges Worked

A source-backed research find about an early technical report on acoustic velocity meters and their performance limitations. This is useful when a general web explanation is no substitute for original evidence.

Unlock the documented reference, its official location, identification details and instructions for navigating the original. The material itself is openly hosted by its source; the fee is for identification and research convenience, not ownership or exclusive access.
