Eliminators
1/2
The combination Line Strainer cum Air Eliminatorensures removal
of solid impurities, air or vapour fromthe liquid before they enter
the bulk meter. It is essentialaccessory for a trouble free and
accurate bulk meteroperation.
DESIGN FEATURES
Low pressure drop due to large filter element area Compact
dimensions for minimum installation
space Quick release lid facilitates regular inspection Threaded
ports for connecting differential pressure
gauge or temperature probe High venting capacity air

PRINCIPLE OF OPERATION
The Line Strainer cum Air Eliminator is fitted on the bulkmeter
inlet. The strainer consists of a fabricated bodywith flanged inlet
and outlet connections. The wiremesh filter element is positively
clamped by the quickrelease lid and lid screw. A drain plug is
provided tofacilitate servicing. Liquid impurities get filtered
onpassing through the filter element and the clean liquid
flows through to the bulk meter. For new installations, itis
advisable to first thoroughly flush lines beforeinstalling the bulk
meter. Periodic filter elementinspection and cleaning is necessary
to prolong the lifeof the bulk meter.
The air eliminator is mounted on the side of the strainerbody.
It consists of a stainless steel float connected to apilot valve
via multiple linkages. When air collects in theair eliminator, the
buoyant force acting on the floatreduces, the float drops down
along with the pilot valve
connected to the linkage and the air escapes throughthe main
valve. As the liquid rises in the air eliminator,
the float rises to lift the pilot valve, thereby closing the
airrelease opening of the main valve.
