DYNArad – Continuous Mass Flow Measurement

DYNArad combines the measurement values of density and velocity (DYNAvel) to determine the mass flow rate at pneumatic conveying processes and free fall applications.

In particular for the flue ash humidification control at power plants (up to 450 t/h) DYNAvel has proved its worth worldwide.

Thanks to the non-contact measurement no maintenance costs arise.

Mode of operation

The radiometric measurement of density is based on the Gamma transmission principle. The radiation, emitted from a shielded source is directed through the pipeline towards a scintillation detector at the opposite side. When irradiating the pipeline, the radiation is attenuated. The extent to which it is attenuated is directly proportional to the density of the measured material, since type of radiation and measuring geometry are constant.
Moreover the measurement performance is not affected by temperature, pressure, viscosity, color or chemical properties of the measured material.

• Non-contacting and non-intrusive
• No wear and tear
• Maintenance-free operation
• Highly accurate and repeatable
• Unaffected by temperature, pressure, dust, colour, conductivity or chemical properties of the medium
• Reliable measurement even under extreme measurement conditions

For details of the velocity measurement please refer to DYNAvel.

The mass flow rate is resulting from density, speed and cross section of the pipe.
