Clamp-on ultrasonic flow meters offer non-invasive measurement without process shutdown, but incorrect pipe data entry and poor transducer placement produce errors above 5%. This guide covers commissioning for GE PT878 and Yokogawa ADMAG clamp-on systems, including pipe geometry input, transducer spacing, coupling compound selection, signal quality verification, and six-step fault isolation.
