2 Area of Application
The strainer is used to prevent measuring errors and
damages caused by impurities contained in liquids.
3 System Design
Strainers are made of a cast (NC models) or a welded
(N models) housing and a filter element with a metallic
fabric liner. The liquid flows from the top down through
the filter element in which the impurities are captured
by the fine-meshed metallic fabric. The filter element
can be removed for cleaning after opening the cover.
Bopp & Reuther Messtechnik GmbH
The NC strainer has conical internal surfaces and
highly radiused edges. These design features
guarantee that the strainer and the connected
pipework are drained completely after opening the
drain plug installed at the lowest position. There is
absolutely no liquid left in the strainer after drainage.
The strainer can be aerated or deaerated via a vent
plug installed at the highest position.
The N/A and N/F models also have a drain plug at the
bottom and a vent plug on the cover. The drained off
liquid will probably contain product residue.
