Chemical slurry applications, like polymer solids in molecular sieve water, can create erratic flow measurements for magnetic flow meters due to noise they create. Operators and technicians often spend hours trying to diagnose these noisy flow rates to no prevail. The simple solution is to dampen the output signal, but this results in delayed response and puts downstream process, equipment, and quality at risk. Using high process noise diagnostics can help to easily troubleshoot process characteristics locally or from the control room. Adjusting the signal processing and frequency can easily cut through the noise and provide stable and fast responding flow measurements.
