Flow

Flow Switches

No-flow and low-flow switches to protect pumps, compressors and heat exchangers.

Flow switches confirm that a fluid is moving and raise an alarm or trip when it isn’t. Options include thermal dispersion switches with no moving parts (ideal for dirty or low-velocity fluids), paddle switches and magnetic switches.
