2-9 In-Line Filter

It is recommended that an in-line filter, such as the Brooks Model 5848, be
installed upstream from the controller to prevent the possibility of any
foreign material entering the meter. The filter porosity should be
approximately ten times smaller than the orifice used in the installation,
however, it is recommended that the minimum porosity that does not
restrict the flow rate being used. The filtering element should be
periodically replaced or cleaned.
