The combination Line Strainer cum Air Eliminator ensures removal of solid impurities, air or vapour from the liquid before it enters the Flow Meter. It is an essential accessory for a trouble free & accurate Flow Meter operation.Download Literature in pdf format.

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 Eliminator.

PRINCIPLES OF OPERATION

The Line Strainer cum Air Eliminator is fitted on Flow Meter inlet. The Strainer consists of a fabricated body with flanged inlet & outlet connections. The wire mesh filter element is positively clamped by the quick release lid & lid screw. A drain plug is provided to facilitate servicing. Liquid impurities get filtered on passing through the filter element & clean liquid flows through the Flow Meter. For new installations, it is advisable to first thoroughly flush lines before installing the Flow Meter. Periodic filter element inspection & cleaning is necessary to prolong the life of the Flow 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 & 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 main valve.
