Clamp-on ultrasonic flow meters are widely used throughout industrial processes in many industries because their noninvasive nature confers inherent advantages over other flow-meter technologies. Material compatibility, contamination, and corrosion risk factors are eliminated. Process integrity is unaffected, and installation costs are much lower.

A portable ultrasonic flow meter contains the same fundamental hardware as a fixed ultrasonic meter. Both use a process transmitter connected to a pair of sensors that are attached to the process piping. But a portable ultrasonic flow meter has unique capabilities that differentiate it from a standard fixed instrument.
