The combination Offset Strainer cum Air Eliminator ensures removal of solid impurities, air or vapour from the liquid before they enter the bulk meter. It is essential accessory for a trouble free and accurate bulk meter operation.

Design features

Low pressure drop due to large filter element area  Compact dimensions for minimum instal ation space threaded ports for connecting differential pressure

Gauge or temperature probe High venting capacity air eliminator

Principle of operation

The Offset Strainer cum Air Eliminator is fitted on bulk meter inlet side and is specifically used with preset meters. The wire mesh filter element is positively

Clamped by a spider, stud and nut arrangement. A drain plug is provided to facilitate servicing. Liquid impurities get filtered on passing through the filter element and

The clean liquid flows through 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 top of the strainer  body. It consists of a stainless steel float connected to a pilot valve via multiple linkages. When the 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 liquid rises in the air eliminator, the float rises to lift the pilot valve, thereby closing the air release opening of main valve.
