The Line Strainer cum Air Eliminator is fitted on the bulk meter inlet. The strainer consists of a fabricated body with flanged inlet and outlet connections. The wire
mesh filter element is positively clamped by the quick release lid and lid screw. A drain plug is provided to facilitate servicing. Liquid impurities get filtered on passing through the filter element and the clean liquid flows through to the bulk meter. For new installations, it is advisable to first thoroughly flush lines before
installing the bulk meter. Periodic filter element inspection and cleaning is necessary to prolong the life of the bulk meter.
The air eliminator is mounted on the side of the strainer body. It consists of a stainless steel float connected to a pilot valve via multiple linkages. When air collects in the air eliminator, the buoyant force acting on the float reduces, the float drops down along with the pilot valve connected to the linkage and the air escapes through the main valve. As the liquid rises in the air eliminator, the float rises to lift the pilot valve, thereby closing the air release opening of the main valve.
