Averaging Pitot Tube
Company - Veris was founded
in 1987 with a vision to develop a flow sensor to significantly
exceed the performance of traditional averaging pitot tube
designs. With 100 years of combined experience in the field
of DP Flow Measurement Technology & opportunity for a new
improved design lead to the birth of VERABAR Flow Element.
VERABAR utilized the much critical aerodynamic & fluid dynamic
principles that other manufacturers overlooked. The VERABAR
has gained world-wide acceptance due to its superior performance.
Principle - In its simplest
form, an averaging pitot tube senses the natural averaged
differential pressures created by the velocity profile of
the fluid flowing in a pipe.
When the fluid impacts the sensor, it creates a high
pressure zone, greater than pipe static pressure, in front
of the sensor. As the fluid moves past the sensor, it accelerates
& a low pressure zone is created to the sides & rear of
the sensor. Multiple sensing ports are positioned in the
high & low pressure zones & an averaged differential pressure
is produced. The DP increases proportionally to the square
of the velocity of the fluid.
Accurate & reliable technology for
measuring gas, liquid & steam.
Developed from Aerospace technology, VERABAR averaging
pitot flow sensor provides unsurpassed accuracy & reliability.
With its solid one piece construction & bullet shape, the
Verabar makes flow measurement clog-free & precise.
Superior Signal Stability & Greater
Resistance to Clogging
Clogging can occur in low pressure ports located in or
near the partial vacuum at the rear of the sensor. The Verabar
design locates the low pressure ports on the sides of the
sensor, forward of the fluid separation point & turbulent
wake area. This virtually eliminates clogging & produces
an extremely stable signal.
Lower Drag & Extended Turndown Scientifically proved
technology of dimples on golf ball lowers aerodynamic drag,
same principle is being used by VERABAR reduce pressure
drag for better stability & extends accuracies at lower
velocities.
Ideal Equipment to replace traditional
technology like Orifice, Flow Nozzle, Venturi, etc.
Advantages of VERABAR over traditional devices
-
- Low Pressure Drop (Energy Conservation).
- No Maintenance Cost.
- Online Insertion-Retraction under flow.
- Installation Cost is negligible.
- Accuracy is maintained for years.
- Single Penetration to Get mass Flow, Pressure, Temperature.
