Slug flow alarms
Slugs – for example, gas in a liquid process or liquid in a gas process – occasionally appear in some
applications. The presence of slugs can significantly affect the process density reading. Slug-flow
limits and duration can help the transmitter suppress extreme changes in reading.
Note: Default slug-flow limits are 0.0 and 5.0 g/cm
3
. Raising the low slug-flow limit or lowering the
high slug-flow limit will increase the possibility of slug flow conditions.
