3.2 Installation of the Measuring Device

3.2.3 Measuring Frames on Chain Conveyors
The same instructions also apply for installation on a chain con-
veyor system. The bottom part of the measuring frame must be
mounted as closely as possible to the chain conveyor.
With this installation, however, one has to make sure that the in-
stallation angle, which is determined at the planning stage, will be
realized. Due to this installation angle, irradiation of a scraper
while the conveyor is moving will be reduced to a small section. As
a result, one will get a smoother output signal.
3.2.4 Installation for Free Fall Measurement
Install measuring frame close to discharge station!
When using the free fall bulk flow meter on pipes, a measuring de-
vice as depicted in Figure 20 is used. The measuring device can
simply be mounted on existing fall-pipes and adjusted via the 4
threaded rods.
