2.1 Overview
The Rosemount® 405C and 1595, based on orifice plate technology, 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.
May 2014
Equation 1
where:
Q = Flow rate
K = Units conversion factor, discharge coefficient, and other factors
DP = Differential pressure
For a more complete discussion on the flow equation, refer to Section 4: Flow Calculations.
2.2 Technical detail
As stated previously, traditional orifice plate flowmeters are based on Bernoulli's theorem,
which states that along any one streamline in a moving fluid, the total energy per unit mass is
constant, being made up of the potential energy (the pressure energy), and the kinetic energy of
the fluid. Where:
where:
P
= Upstream pressure

P
= Downstream pressure
2
p = Density
= Upstream velocity
V

V
= Downstream velocity

When fluid passes through the orifice the velocity of the fluid through the orifice increases. This
increase in fluid velocity causes the kinetic energy of the fluid immediately downstream of the
orifice plate to increase, while simultaneously decreasing the static pressure energy of the fluid
at that same point. By sensing the static pressure on the upstream and downstream sides of the
orifice plate, the fluid velocity can be determined.

Theoretical
May 2014
Some assumptions were made in deriving the theoretical equation, which in practice are not
valid:
a. Energy is conserved in the flow stream.
b. Pressure taps are at ideal locations.
c. Velocity profile is flat.
These items are corrected by the discharge coefficient which is derived from experimental data
and is different for each primary element.
Discharge Coefficient C =
2.3 Conditioning orifice meter technology
The Rosemount 405C and 1595 Conditioning Orifice Plate has the added advantage of being
able to operate with reduced straight run requirements. With its multiple orifices in the flow
stream it is much less susceptible to velocity profile distortion, swirl, and secondary flows. If the
velocity profile is skewed, each of the orifices will conduct a part of the total fluid flow within the
pipe. The fluid pressure on the downstream side of the conditioning plate that is attributable to
each of the separate orifices will be averaged within the fluid to provide an average downstream
pressure. The average downstream pressure is compared with the upstream pressure to provide
an average differential pressure for whatever velocity profile is presented to the multiple orifice
plate, resulting in an accurate measurement of the rate of fluid flow in the pipe.
Reference Manual
00821-0200-4810, Rev BA
As mentioned in an earlier section, every 405C and 1595 is flow calibrated as part of the
manufacturing process. The purpose of this calibration is to determine a calibration factor
which is applied to the flow calculations as an adjustment to correct for bias error from the
ISO-5167 discharge coefficient equations. This results in an accurate flowmeter which conforms
to the ISO-5167 equations.

The following descriptions of tests and testing methods are abbreviated versions. For detailed
descriptions of the individual laboratories contact the facility in question.
3.2 Testing laboratories
May 2014
CEESI, Colorado
Colorado Engineering Experiment Station, Inc. (CEESI) in Nunn, Colorado has a multi phase flow
test facility using natural gas and hydrocarbon liquids. The facility accommodates line sizes from
2 to 8 inch at a max pressure of 1440 Psi. The facility operates at temperatures ranging from
ambient to 122 °F. See Appendix A Additional Graphs for a diagram of CEESI facility.
Lean natural gas is brought into the CEESI complex at a low pressure of near 0.3 Mpa (50 psi). A
charging compressor is used to pressurize the test loop to the desired operating pressure for the
test being conducted. The normal operating pressure range is between 0.7 to 9.9 Mpa (100 to
1440 psi). Once the loop is pressurized, any combination of the four positive displacement
compressors can be used to circulate the natural gas around the test loop at the desired
velocity. Both a turbine meter and a subsonic venturi measure the mass flow rate of the natural
gas. The difference in mass flow rate between these two meters is monitored; and if the
difference exceeds a specified amount, the data is scrutinized for detrimental effects such as
pulsation. If the difference is within tolerance, then all other meters installed in the test loop can
be compared to the natural gas mass flow rate as measured by the turbine meter.
The hydrocarbon liquid, which resides in the liquid storage vessel, can be injected into the gas
stream by positive displacement pumps (triplex pumps). Coriolis meters measure the liquid
mass flow rate and the density of the injected liquid. The gas stream carries the liquid through
the meter test locations to the horizontal separator where it is then returned to the liquid
storage vessel. Coriolis meters again measure the mass flow rate and the density of the returned
liquid. When the injected liquid mass flow rate is equal to the return liquid mass flow rate and all
pressures and temperatures within the loop are constant with time; the system is at a steady
state condition and test data can be acquired.
