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 recognized.

The measurement principle is based on the detection of moving electrical charges which naturally adhere to the solids surface and are produced e.g. through friction on the hose-wall. Only moving particles generate a signal.

The hose is simply passed through the instrument (version T) and is tightened with the hose fittings. In applications with conductive hoses, or in cases where the
hose must be cut for installation, the version E is used. Here the hose is plugged into hose fittings from two sides.
