How Verabar Works
Verabar's superior performance is due
to its shape, surface roughness, and
low pressure port location
Verabar senses and averages the natural
pressures created by the velocity profile

Profile
Verabar Outperforms Other Insert Meters
• Velocity profiles vary with upstream pipe configuration and disturbances.
• The Verabar averages the profile.
• Other insert meters only sense a single point.

– Stable signal
– Low drag and increased structural strength
– Solid one-piece

Verabar's Non-Clog Design
•Low-pressure ports located on sensor sides
•virtually eliminate clogging and produce an
•extremely stable signal

Advantages of
Frontal Surface Roughness
•Turbulent Boundary Layer:
–Lowers drag and vortex- shedding forces by 50%
–Predictable, constant drag coefficient
•Dormant/Laminar Boundary Layer:
– Increases drag and vortex-shedding forces
– Unpredictable drag coefficient

Verabar's No-Leak Construction
•Verabar Flow Sensor– Solid, one-piece
construction
– No leaks between chambers
•Competitors' Construction– Tubes within a tube can leak
due to vibration or changes in pressure or temperature

ACCELABAR DESIGN
The INLET is a
patented
torroidal radius
that accelerates
and conditions
the flow to
produce a
linear velocity
profile
The STRAIGHTENING & SETTLING
ZONE stabilizes & linearizes the
velocity profile
The DIFFUSER is
a gradual increase
in the diameter
to reduce the
permanent

Armstrong Vortex Meter
A Little History Lesson:• Vortices were first observed by Leonardo De Vinci in the
early 1500’s• About 400 years later Theodore von Kármán observed the
repeating pattern of swirling vortices caused by the unsteady separation of flow of a fluid around blunt bodies, named the von Kármán vortex street
