Daniel Straightening Vanes

Consistent flow profile for improved meter performance and accuracy

These vanes are installed in the upstream section of meter tubes to reduce flow disturbance preceding the orifice plate. Disturbance is often created by complex piping or valves which precede the orifice metering section. As flow passes through the vane bundle, the disturbance is straightened and smoothed to a normal flow pattern.

Straightening vanes are economical because they allow upstream piping lengths to be minimized, saving space and reducing costs.

The tubes in each Daniel vane bundle are welded at both ends at each point of tangency. Tube inlets and outlets are reamed to permit minimum pressure drop. Special spacer lugs on each vane bundle assure a perfect fit in the meter tube.
