The microwave-indicator DYNAguard M is used for monitoring the mass flow in open and closed transport processes also with big distances between sensor and conveyed material.

Independent of particles moving direction solid materials with velocity of at least 0.1 m/s will be detected by passing the microwave field.

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.

DYNAguard M has to be installed with an angle of 45° up to 90° of flow direction. Moving mechanical parts e.g. rotary valves, propellers or similar should not be in the detection field, because this might be detected as flow of material. If these 'disturbance source' can not be displaced, they have to be shielded or a DYNAguard of electrostatic type as DYNAguard P should be used.
