received is proportional to the concentration of the radiating medium in the conveyed
material.
3.2.10 Installation conditions for flow measurement
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

) and the density of the carrier liquid (ρ

) are also known, the solids flow rate can be calculated.

Measurement of mass flow (solids)
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.
