High Process Noise Field Guide - Emerson

2019-1-18  The Rosemount High Process Noise diagnostic detects if there is a process condition causing unstable or noisy readings, but the noise is not real flow variation. One common cause of high process noise is slurry flow, like pulp stock or mining slurries. Other conditions that cause this diagnostic to activate are high levels of chemical reaction or entrained gas in the liquid. If unusual noise or variation is seen, this diagnostic will activate and deliver a PlantWebTMalert. If this situation exists and is left without remedy, it will add additional uncertainty and noise
