The indicator of DYNAguard K helps to monitor the mass flow in solid material handling applications such as pneumatic transport lines, feeders or gravity chutes in a wide range of mass flow from g/h to t/h.
Conveying or feeding problems of powders, pellets or granules are detected early and thus should be avoided. This helps to prevent plant failures like clogging, material loss, idle or other serious difficulties.
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 device is not applicable for solids which build up an electrical conducting layer on the sensor through friction or deposition.
