Immediately pinpoint the cause of minor flow disturbances with the Rosemount 3416 4+2 Ultrasonic Flow Meter that delivers the power and performance of a field-proven Rosemount four-path, British Gas-design chordal meter (certified to OIML R137 1&:2 Accuracy Class 0.5) and a two-path, reflective check meter in one body. A highly sensitive, vertical 90° path quickly detects trace amounts of liquid and other debris at the bottom of the pipe that can significantly increase lost and unaccounted for (LAUF) gas. A wealth of predictive diagnostics are generated by ultra-fast 3410 Series Electronics and are displayed via MeterLink™ Software to help detect costly process upsets in real time.
