Process Analyzer Sample Flow
Process analyzers are designed to accurately and continuously measure a target analyte in a process stream. Sampling is the single most critical issue for process analysis. When the sampling system becomes plugged, it can cause big problems and costly, unscheduled maintenance.The Brooks Model MT3750 variable area meter – with 4-20mA output – continuously monitors sample flow to the analyzer, unlike a flow alarm or flow switch. When flow starts to drop – indicating the onset of plugging – users can schedule maintenance to clear the problem before the analyzer is starved of sample.
Many analyzer sample systems use a “fast loop” bypass flow to rapidly move sample to the analyzer. It is frequently useful to instrument this line with a continuously transmitting variable area meter as well.
