Smith Meter® Vertical Air Eliminator - VAR Series

Brand: TechnipFMC
Request a Quote
Smith Meter® Model VAR Air Eliminator separates and releases air or gas from petroleum or other liquids before they are passed through the meter.

Complete elimination of air or gas is essential for accurate metering, making the Smith Meter Model VAR Air Eliminator a necessary part of a metering system when there is a possibility of air or gas being present in the flow stream.

Principles of Operation

The vertical air release tank has a tangential straight through design.

The inlet of the VAR tank is located in the upper quartile, while the outlet is opposite of the inlet in the lower quartile.

As fluid enters the inlet, the product is forced in a rotational movement.

This operation acts as a centrifuge and forces the liquid to the interior wall of the vessel and downward while the gas or air is forced to the center of the vessel and upward, effectively separating the air from the liquid.

The air is then vented via the air release head to a safe environment.
Features
  • For refined products
  • Viscosity up to 45 mPas (200 SSU)
  • Vertical Design saves horizontal space
  • Tangential Inlet and Outlet creates a circular flow path and centrifugal force to help separate air from liquid
  • RB Mechanical Air Release Head
  • DE Air Release Head with electric float switches for use with electrically-activated block valves or AccuLoad controller
  • Code Conformance with ASME Code Section VIII
  • Post Weld Heat Treatment (PWHT) is standard on all VAR tanks. Therefore, suitable for Ethanol or Ethanol blending services
