Installation with very coarse-grained and sharp edged bulk material

With sharp edged filling material or filling material with large granulations we recommend the installation of rejecting devices. The diagram shows an example:

Warning: The indicator may not lie in the flow of the filling material, otherwise the indicator and diaphragm will rapidly be damaged!

 
A Rejection device - protects level indicator and diaphragm from damages caused by falling filling material.
B Curtain made od rubber or plastic - protects the diaphragm against high abrasion, because it lies over the diaphragm, if the filling level increases.
C Level indicator
