STRAIGHTENING VANES
CATALOG 1100
REDUCE FLOW DISTURBANCE AND IMPROVE YOUR ORIFICE METERING CONDITIONS
Daniel Straightening 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
their use often allows sufficient reduction of upstream
meter tube length, so that a smaller building or enclosure
is possible. (See Daniel Meter Tube Catalog Section "D"
for meter tube lengths.)
Daniel Straightening Vanes are manufactured in a variety
of sizes, in carbon steel and stainless steel. They are in
accordance with recommendations of the A.G.A. and
A.S.M.E., as well as numerous other societies and
associations. Three standard vane bundles are shown in
the document entitled "Standard Straightening Vane
Bundles." Each type bundle is available in a Flange Model
and a Line Model.
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.
The Flange Model is held in the line by a flange ring which
is clamped between two pipe line flanges.
Straightening Vane Uses (Stainless Steel)
Daniel Stainless Steel Straightening Vanes
Stainless steel vanes are particularly useful in meter tubes handling corrosive flows, in buried meter tubes, or in
tubes having condensate problems. The standard material for these Daniel vanes is 304 stainless steel.

Method of Installing Line Model Vane
As shown in the cross-section view below, the Line Model vane is first located in the pipe with its welded pad
squarely beneath the tapped hole. An Allenhead set screw is installed so that it seats into a counter sunk hole
in the welded pad. The screw is tightened to exert pressure on the welded pad, clamping the vane bundle
securely in the line. To seal off the tapped hole in the pipe, a half-coupling is located over the set screw and a
steel pipe plug inserted and tightened. The 3/8" set screw is 3/8" -- 16 N.C., and the 1/2" set screw is 1/2" -- 13
N.C. A nominal charge is made for factory installation of Line Model vanes. These vanes are intended for
horizontal installation only. For vertical service, contact factory.
