Measurement of mass flow (liquids)
The density signal determined by the Gammapilot FMG50 is transmitted to the Promag 55S. The
Promag 55S measures the volume flow; the Promag can determine a mass flow in connection with
the calculated density value.

 1 Mass flow measurement (m) using a density meter and a flowmeter. If the density of the solids (ρ
s
) and
the density of the carrier liquid (ρ
c
) are also known, the solids flow rate can be calculated.

Bulk solids applications on conveyor belts and conveyor screws.
The source container is positioned above the conveyor belt and the Gammapilot FMG50 below the
conveyor belt. The radiation is attenuated by the medium on the conveyor belt. The intensity of the
radiation received is proportional to the density of the medium. The mass flow is calculated from the
belt speed and the radiation intensity.
