CHAPTER 14 - MEASUREMENTS IN PRESSURE CONDUITS
17. Acoustic Flowmeters
The most recent advances in measuring flow in pressure conduits has been with the further developments of acoustic flowmeters. This class of meters is covered in detail in chapter 11 of this manual. These meters are used extensively at powerplants and other major points of diversion. They are well suited to use in automated data acquisition systems. Their accuracy depends on type and installation, but generally varies from +/-3 percent down to +/-0.1 percent.
