OVERVIEW
The Rosemount Annubar primary flow element is a device used to measure
the flow of a liquid, gas or steam fluid that flows through a pipe. It enables flow
measurement by creating a differential pressure (DP) that is proportional to
the square of the velocity of the fluid in the pipe, in accordance with Bernoulli's
theorem. This DP is measured and converted into a flow rate using a
secondary device, such as a DP pressure transmitter.
The flow is related to DP through the following relationship.
Equation 2-1
QK DP
where:
Q = Flow Rate
K = Annubar Flow Coefficient
DP = Differential Pressure
For a more complete discussion on the flow equation, refer to Section 4:
Annubar Flow Theory.
The Annubar generates a DP by creating blockage in the pipe and acting as
an obstruction to the fluid. The velocity of the fluid is decreased and stalled as
it reaches the front surface the Annubar sensor, creating the impact/high
pressure.
The Rosemount Annubar senses the impact pressure by utilizing either a
frontal slot (485) or sensing hole (585) design, which opens into the high
pressure chamber. This high pressure chamber connects directly into the DP
transmitter for measurement.

Rosemount 585 Annubar in a
Flow Stream
As the fluid continues around the Annubar sensor, it creates a lower velocity
profile on the backside of the sensor, creating the low/suction pressure
downstream of the Annubar. Individual ports, located on the backside of the
Annubar sensor measure this low pressure. Working on the same principle as
the high pressure, an average low pressure is maintained in the low pressure
chamber that connects directly into the transmitter for measurement.
The resultant differential pressure is the difference between the impact (high)
pressure reading and the suction (low) pressure reading as seen below.

Rosemount 485 Annubar
Sensor Design
The 485 Annubar is T-shaped in design and is constructed in three scaled
sizes for use in a wide range of pipe diameters. Its design includes a single
high-pressure plenum, three common low-pressure plenums, and an integral
thermowell.

Differential Pressure (DP) Signal
The T-shaped design of the 485 Annubar generates more differential
pressure than any APT. The flat upstream surface of the sensor is
perpendicular to the direction of flow, which results in a high and very stable
drag coefficient. Since the flow coefficient, or k factor (see Equation 2-1), is a
function of the drag coefficient, this produces a large, repeatable and
predictable DP signal for a given velocity.
The magnitude of the DP signal is directly related to measurement accuracy
and the amount of primary element turndown, particularly at lower flow rates.
One traditional limitation of APT technology is that accuracy degrades at
lower flow rates as a result of the minimal DP produced. The Rosemount 485
extends the lower range limit that an APT can measure and maintain
performance as a result of the additional DP generated.
Impact (High) Pressure Measurement
As mentioned in the “Overview” on page 2-1, the Rosemount 485 Annubar
measures the impact (high) pressure with a frontal slot design. The laser cut
slots extend across the entire front surface of the sensor to maximize the
amount of the velocity flow profile measured and increase the accuracy of the
measurement. Multiple slots are used to maintain the structural integrity of the
bar. A seal weld is visible around the perimeter of the slots and is used to seal
the high pressure chamber from the low pressure chamber to prevent any
leakage potential. Testing revealed that the raised surface of the weld does
not have any effect on performance so it is not removed.

The patented slot design replaces sensing ports used by traditional APTs.
This slot “integrates” the velocity flow profile and improves the accuracy of the
measurement. By “integrating” the flow profile, a consistent series of data is
recorded across the pipe diameter instead of limited samples taken at a few
discreet points. By increasing the number of samples taken across the pipe of
the actual flow rate, the accuracy of the measurement is improved.

Suction (Low) Pressure Measurement
The Rosemount 485 Annubar measures the suction (low) pressure with
sensing ports located in stagnation zones on the backside of the sensor. As
the fluid comes into contact with the 485 Annubar sensor and separates from
the front edges, the velocity and turbulence level of the fluid in the area
directly behind the sensor is greatly decreased. The low velocity and
turbulence level in this stagnation zone significantly reduces any pressure
variation in this region. Individual sensing ports are drilled in this location to
detect the suction (low) pressure.
The number of ports located on the backside of a given sensor is a function of
pipe size and mathematically determined by the same Chebyshev principles
of previous Annubar designs.

Surface Texture
As the flow over any surface in the flow stream is increased, the character of
the fluid flow near that surface goes through a transition. At a certain critical
flow rate, the level of turbulence in this region, termed the boundary layer,
increases sharply. This increase in turbulence in the boundary layer on the
front surface of the 485 Annubar causes a marked change in the separation of
the flow at the edge, which in turn affects the accuracy of the differential
pressure signal. The transition from the non-turbulent (laminar) to a turbulent
boundary layer condition is an inescapable fact described by the principles of
fluid dynamics. However, it has been found that altering the roughness or
texture of the surface adjacent to the boundary layer can control the flow at
which that transition takes place.

The front surface of the 485 Annubar sensor is tailored to the customer's flow
application. In high flow applications (where the maximum expected flow
exceeds one million Reynolds number), the surface is textured to increase the
level of turbulence at a given flow rate. This ensures that the transition from
laminar to turbulent flow in the boundary layer occurs at flows below (and
outside) the customer's measurement range. For lower flow applications, the
surface is left smooth to maintain a laminar boundary layer forcing the
transition to occur above the maximum flow that will be seen in the
application.

the Annubar produce a more consistent separation point, resulting in a flow
coefficient that is linear over the entire range of pipe reynolds numbers that
are typically encountered in flow measurement applications.

FLOW COEFFICIENT
OVERVIEW
The flow coefficient (K–factor) is the ratio of the actual flow rate to the
calculated (theoretical) flow rate. The accuracy of the Rosemount Annubar
relates directly to the flow coefficient. The flow coefficient is empirically
determined by testing a representative sample of flowmeters to establish the
relationship between flowrate and the DP induced across the primary
element.
This sampling of flow coefficients is generally plotted as a function of key
flow-meter variables. For averaging pitot tubes, flow coefficients are plotted
against the meter's pipe blockage.
Curve-fitting techniques are used to generate an equation that best fits the
sampling of flow coefficients. This curve-fit equation becomes the basis for a
manufacturer's published flow coefficients. These published flow coefficients
are used for flowmeters in nearly all untested conditions.
Rosemount has supplemented the flow coefficient equations discussed above
with the blockage equation derived in Section 4 of this document. This
blockage equation defines a relationship between flow coefficient and
blockage that substantiates the results of empirical testing. Extensive APT
testing conducted by Rosemount over the past 35 years support the
theoretical equation.
BENEFITS
The K-factor of an Annubar is a function of the blockage the probe presents to
the flow stream. The flow coefficient of many other primary elements is a
function of Reynolds number. This characteristic of Annubar performance
offers significant benefits over other primary elements.
K-factor independence can be attributed to a constant separation point at the
edges of the Annubar and to the probe's ability to take a proper average.
Thus:

It allows measurement of a wide range of Reynolds numbers without a
correction factor for changing Reynolds numbers.
•
Any variations in the K-factor with changing Reynolds number are due
to scatter and fall within ±0.75% of the published K-value for the 485
Annubar.
•
Any variations in the K-factor with changing Reynolds number are due
to scatter and fall within ±1.50% of the published K-value for the 585

The K-to-blockage theoretical link demonstrates a higher degree of
confidence in Rosemount Annubar K-factors than shown by flowmeters that
use only an empirical database to determine flow coefficients. Rosemount is
the first company to identify and use theoretical equations linking
self-averaging pitot-tube flow coefficients to pipe blockage.
ROSEMOUNT ANNUBAR
REYNOLDS NUMBER
RANGES
For a Rosemount Annubar to operate accurately, the flowing media must
travel at a velocity sufficient to separate from the edges of the Annubar.
Drag coefficients, lift coefficients, separation points, and pressure distributions
around bluff bodies are best described by “rod” Reynolds numbers. There is a
minimum rod Reynolds number at which the flowing fluid will not properly
separate from the edges of the T shape. The rod Reynolds number can be
calculated using Equation 3-1.

FLOW EQUATION
DERIVATION
00821-0100-4809, Rev BA
July 2009
The flow equation relates the DP induced across a primary element to the
velocity of the fluid in the pipe. As with other differential-pressure flowmeters,
Rosemount Annubar equations are based on the Bernoulli equation:
2
Equation 4-1
2
V1
P
V2
P
--------- + ------1 + g c z 1 = --------+ ------2 + g c z 2
2g c  1
2g c  2
For incompressible fluids 1 = 2. Changes in elevation around a primary
element are negligible so z1 = z2.
Also, assume the velocity just within the mouth of the impact-sensing ports is
zero, (V1 = 0). While minor circulation may occur within the high pressure
chamber of the Rosemount Annubar, this flow is extremely small and may be
considered negligible.
Solving for V2 yields:
Equation 4-2
V2 =
 P1 – P2 
2g c -----------------------
The net differential pressure produced can be rewritten as:
Equation 4-3
P1 – P2
h = ------------------
Substituting Equation 4-3 into Equation 4-2 yields:
Equation 4-4
V2 =
2g c h
Like the orifice plate and venturi meter, the general equation describing the
actual flow in a pipe for the Rosemount Annubar is:
Equation 4-5
Q a = K A AV
In Equation 4-4, V2 is the average velocity of the fluid traveling past the
sensor on the downstream side; whereas, in Equation 4-5, V is the average
velocity in the pipe. Differences between these two velocities (V2 and V) are
absorbed in the flow coefficient (KA).
Combining Equation 4-4 and Equation 4-5 yields:
Equation 4-6
Q a = K A A 1 2g c h
Equation 4-6 is the flow equation used to relate differential pressure induced
across the primary element to flow rate for the Rosemount Annubar.

BLOCKAGE EQUATION
DERIVATION
Because the flow coefficient compensates for the difference between V2 and
V, it must be recognized that (KA) will be a function of the amount of
obstructed area the sensor itself causes in the pipe. More specifically, (KA) is
a function of the sensor's blockage in the pipe.
Equation 4-7
KA = f  B 
This is analogous to the velocity-of-approach factor for an orifice plate or a
venturi meter. The following derivation uniquely determines f(B) in
Equation 4-7. Discussion is limited to fluid flows in the turbulent regime for
which Rosemount Annubar flow measurement is intended. Development of
the equations applies to primary flow elements that are geometrically similar.
Beginning with Equation 4-6, the differential pressure produced by a primary
flow element can be dissected into two parts:
• Differential pressure due to the primary flow element's blockage (hB)
• Differential pressure due to the shape of the primary flow element (hS)
Focusing on the differential pressure contribution due to the primary flow
element's blockage (hB), Equation 4-1 can be rearranged:
Equation 4-8
 P1 – P2 

- = ---------  V 2 – V 1 
h B = ----------------------2g c

In the derivation of the blockage equation V1 is defined as the average fluid
velocity in the pipe prior to encountering the primary flow element, V2 equals
the accelerated velocity past the primary flow element.
Using the conservation of mass:
Equation 4-9
A1 V1 1 = A2 V2 2
For incompressible fluids, 1 = 2, Equation 4-9 can be simplified:
Equation 4-10
A1
V 2 = ------ V 1
A2
Where:
A1 = Cross-sectional area of the pipe
A2 = Cross-sectional area of the pipe less the amount blocked by the sensor
A2 can be rewritten in terms of A and the flow element's blockage:
Equation 4-11
A 2 =  1 – B A 1
Substituting into Equation 4-10 yields:

Where C1 = constant of integration, solve for KA, redefining the integration
constant C1 as 2C1.
Equation 4-21
1 – B
K A = ----------------------------------------2
1 – C1  1 – B 
(B) represents the actual blockage in the pipe caused by the Rosemount
Annubar. Because downstream pressure is sensed past the flow element's
widest cross-section, the effective blockage of the sensor will be a fraction of
the actual blockage. Therefore, define an effective blockage as C2B where C2
represents a fraction of the actual blockage. Equation 4-21 can be rewritten:
Equation 4-22
 1 – C2 B 
K A = ------------------------------------------------2
1 – C1  1 – C2 B 
Equation 4-22 shows that there is a direct relationship between a primary flow
element flow coefficient KA and its blockage. As blockage approaches zero,
Equation 4-22 becomes:
Equation 4-23
KA
B0
1
= -------------------1 – C1
Thus, as blockage approaches zero, the primary flow element flow coefficient
1
approaches a constant value -------------------, the stream-flow coefficient.
1 – C1
This constant value is the primary flow element flow coefficient due only to the
primary flow element's shape (hS), and is analogous to placing the primary
flow element in an infinitely large pipe with no confining walls.
The constants C1 and C2 in Equation 4-22 are determined experimentally.
Once determined, Equation 4-22 becomes the theoretical link between the
flow coefficient and the flow element blockage.
CONCLUSION
While empirical testing of a flowmeter is the most accurate means of
determining the meter's flow coefficient, many flowmeters use untested
predicted flow coefficient.
• Untested flow coefficients are based on a representative sample of
empirically determined flow coefficients and on theories that link the
flow coefficient to physical parameters in the pipe.
• Like an orifice plate or a venturi meter, an averaging pitot tube has a
theoretical relationship between its flow coefficient and parameters in
the pipe.
• An averaging pitot tube's flow coefficient is related to its blockage in the
pipe. This blockage dependency is necessary because the sensor itself
reduces the effective pipe flow area.
• For an orifice plate and a venturi meter, the velocity-of-approach factor
is the theoretical link between the meter's flow coefficient and it's beta
ratio. For a Rosemount Annubar, Equation 4-22 describes the
theoretical relationship between the sensor's flow coefficient and its
blockage in the pipe.
• Using a theoretical basis, in addition to empirical testing, for the
prediction of untested flow coefficients provides a much higher degree
of confidence in these untested values.

OVERVIEW
The following descriptions of tests and testing methods are abbreviated
versions. For detailed descriptions of the individual laboratories contact the
facility in question.
TESTING
LABORATORIES
Rosemount Boulder,
Colorado Flow
Laboratory
The Rosemount Annubars are tested and calibrated in water at Rosemount
Inc. Line sizes available for testing range from 0.50 in. to 12 in. A secondary
set of reference meters, routinely calibrated against a gravimetric primary
standard, provide an uncertainty of 0.25 percent. Calibrations that use the
primary-measurement device, gravimetric method, can be calibrated with an
uncertainty of 0.1 percent.
Alden Research
Laboratories (ARL)
Flowmeters are calibrated at ARL using the gravimetric method. This method
has been found to produce a consistent accuracy of ±0.25% over extended
periods.
SwRI Gas Research
Institute (GRI), Meter
Research Facility (MRF)
Flowmeters are tested and calibrated on a recirculating natural gas loop. A
sonic nozzle bank provides secondary flow calibration. This permits high
repeatability and excellent test accuracies via calibration against the
gravimetric primary standards. The sonic nozzle banks produce an accuracy
on flow rate of 0.25% of reading.
Utah Water Research
Laboratories (UWRL)
Flowmeters are calibrated at UWRL using either calibrated nozzles or
gravimetric method.
Colorado Engineering
Experimental Sation Inc
(CEESI)
CEESI has two facilities, using different calibration methods:
www.rosemount.com
•
The Nunn, Colorado Facility uses compressed air stored in cylinders
and discharged through a calibrated nozzle.
•
The Garner IA Facility uses high-pressure natural gas from a
transmission line that is measured via a calibrated nozzle.

Piping is selected to match the inside diameter of the flowmeter under test.
Carbon steel piping is normally used for these tests. Gaskets between pipe
flanges are carefully installed and checked to ensure that they not interfere
with the flow. Proper alignment of the flowmeter with the piping is maintained.
After all piping is secured with bolts, couplings, or clamps. Water is gradually
introduced into the line. Flows are set to purge air from the system and to
bring the flowmeter to steady-state temperature. After operating the system
for a period of time, the control valve (at the downstream end of the test line)
is closed. Air is then purged from all instrumentation lines, instruments, and
the flowmeter.
After air purging, and with the control valve in the closed position, all
instrumentation is checked for zero-flow indication. Calibration test runs are
not started until all instrumentation reads zero at the no flow condition.
The flow rate is set by adjusting the control valve at the end of the test line to
a desired flow. This flow is allowed to stabilize and reach steady-state
condition. This condition is achieved when the average flow-meter readout is
constant with time. At this point, the calibration run begins.
A calibration run consists of simultaneously recording the flowmeter output
while the weighing tank is filled and the filling process is timed. Electronic
timers are activated and deactivated by electric eyes on the switch way.
Outputs are recorded at 1–15 Hz during this time. The duration of the run is
typically between 50 and 100 seconds. For higher flow rates, the limiting
factor is the capacity of the weighing tank.
In addition to recording weight and time, the water temperature, air
temperature weigh tank, and air temperature adjacent to the readout are
recorded. Barometric pressure is also recorded at the start and at the end of
the test.
After a run is completed, the control valve is reset to another flow rate and the
process is repeated. Runs are normally conducted at 12 different flow rates,
approximately equally spaced from the maximum to the minimum flow rates.
In some cases, the maximum flow obtainable by the test facility determines
the upper flow limit of the test.
