The flow switch DYNAguard S is used to monitor the flow of solids in flexible hoses. It indicates through a relay output when a threshold is exceeded. The version with analogue output (4…20 mA) can additionally indicate a flow trend.
When granulates, powders, blasting material, abrasives, dust or other solids are (pneumatically) transported, blockages, an empty hopper, rat holing or a product-bridge at the bottom of a storage tank can immediately and securely be recognised.
