During a recent plant audit, we counted 47 ultrasonic flowmeters monitoring everything from chilled water to diesel fuel – each chosen for specific advantages over other technologies.

Ultrasonic flowmeters excel in non-invasive liquid measurement across industries including water/wastewater (60% market share), oil & gas (25%), and chemical processing (15%). They’re ideal for large pipes where shutdowns are costly, clean fluids, and bidirectional flow applications.
