SW
Flow monitor, electronic, single-stage
Application
The SW is a flow monitor (based on thermodynamics without moving parts) for liquid and gaseous media in pipelines as a flow monitor or lowwater protection, like pumps in cooling circuits, refrigerating machines, evaporators, compressors and heat exchangers.
