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.

Accurate & Trouble-Free Performance– No clogging

– 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

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
