The indicator DYNAguard P is used for monitoring the mass flow in solid material handling applications such as pneumatic transport lines, free fall pipes, chutes or hopper in a wide range of mass flow from g/h to t/h.

The meter detects moving electrical charges that are produced, for example, through friction with other objects such as the pipe wall and then naturally adhere to the solids surface solids, solid lining will not be detected.

The detection area goes some centimeters around the sensor plate so that nearby located moving components as e.g. flaps do not have any influence.

Due to the measuring principle also moving massive compact solids as plates or rods can be monitored.

The device is not applicable for solids which build up an electrical conducting layer on the sensor surface through friction or deposition.
