ELITE Series Coriolis Flow and Density Meters
Measurement principles
As a practical application of the Coriolis effect, the Coriolis mass flow meter operating principle involves inducing a vibration of the
flow tube through which the fluid passes. The vibration, though it is not completely circular, provides the rotating reference frame
which gives rise to the Coriolis effect. While specific methods vary according to the design of the flow meter, sensors monitor and
analyze changes in frequency, phase shift, and amplitude of the vibrating flow tubes. The changes observed represent the mass
flow rate and density of the fluid.
Mass and volume flow measurement
The measuring tubes are forced to oscillate producing a sine wave. At zero flow, the two tubes vibrate in phase with each other.
When flow is introduced, the Coriolis forces cause the tubes to twist resulting in a phase shift. The time difference between the
waves is measured and is directly proportional to the mass flow rate. Volume flow rate is calculated from mass flow rate and the
density measurement.

Density measurement
The measuring tubes are vibrated at their natural frequency. A change in the mass of the fluid contained inside the tubes causes a
corresponding change to the tube natural frequency. The frequency change of the tube is used to calculate density.

Temperature measurement
Temperature is a measured variable that is available as an output. The temperature is also used internal to the sensor to
compensate for temperature influences on Young’s Modulus of Elasticity.
Meter characteristics
■
Measurement accuracy is a function of fluid mass flow rate independent of operating temperature, pressure, or composition.
However, pressure drop through the sensor is dependent upon operating temperature, pressure, and fluid composition.
■
Specifications and capabilities vary by model and certain models may have fewer available options. For detailed information
regarding performance and capabilities, either contact customer service or visit www.emerson.com/flowmeasurement.
■
All meters with the CMF designation (CMF, CMFHC, CMFS) are members of the ELITE meter family and should be considered to
possess the same qualities and specifications as other ELITE family meters unless specifically noted.
■
The letter at the end of the base model code (for example, CMF100M) represents wetted part material and/or application
designation: M = 316L stainless steel, L = 304L stainless steel, H = nickel alloy C22, P = high pressure, A = high temperature 316L
stainless steel, B = high temperature nickel alloy C22, Y = super duplex (UNS S32750). Detailed information about the complete
product model codes are described later in this document.

Gas flow rates
When selecting sensors for gas applications, pressure drop and turndown through the sensor is dependent upon operating
temperature, pressure, and fluid composition. Therefore, when selecting a sensor for any particular gas application, it is highly
recommended that each sensor be sized using the sizing and selection tool at www.emerson.com/flowmeasurement that will
report both the actual velocity and the sonic velocity for each flow rate and meter size considered.
Use the following equation to determine general recommendations on nominal and maximum gas mass flow rates:

Note
Gas maximum flow rate can never be greater than the maximum liquid rate. Assume that the lower of the two rates is applicable.
Gas mass flow rate
Use Mach number “0.2” for calculating typical nominal rate; use Mach number “0.3” for calculating maximum
recommended rate. When Mach Numbers are above 0.3, most gas flows become compressible and significant
increases in pressure drop may occur regardless of measurement device.

Zero stability
Zero stability is used when the flow rate approaches the low end of the flow range where the meter accuracy begins to deviate from
the stated accuracy rating, as depicted in the turndown section. When operating at flow rates where meter accuracy begins to
deviate from the stated accuracy rating, accuracy is governed by the formula: accuracy = (zero stability/flow rate) x 100%.
Repeatability is similarly affected by low flow conditions.
Turndown
The graph and table below represent an example of the measurement characteristics under various flow conditions. At flow rates
requiring large turndowns (greater than 30:1), the zero stability values may begin to govern capability dependent upon flow
conditions and meter in use.

Temperature limits
Sensors can be used in the process and ambient temperature ranges shown in the temperature limit graphs. For the purposes of
selecting electronics options, temperature limit graphs should be used only as a general guide. If your process conditions are close
to the gray area, consult with your Micro Motion representative.
Note
■
In all cases, the electronics cannot be operated where the ambient temperature is below -40 °F (-40.0 °C) or above 140 °F
(60.0 °C). If a sensor is to be used where the ambient temperature is outside of the range permissible for the electronics, the
electronics must be remotely located where the ambient temperature is within the permissible range, as indicated by the
shaded areas of the temperature limit graphs.

■
The extended-mount electronics option allows the sensor case to be insulated without covering the transmitter, core
processor, or junction box, but does not affect temperature ratings. When insulating the sensor case at elevated process
temperatures above 140 °F (60.0 °C), ensure electronics are not enclosed in insulation as this may lead to electronics failure.
■
For the CMFS007 sensor, the difference between the process fluid temperature and the average temperature of the case must
be less than 210 °F (99 °C)

Process temperature effect
■
For mass flow measurement, process temperature effect is defined as the change in sensor flow accuracy specification due to
process temperature change away from the calibration temperature. Use the Zero Verification and Smart Meter Verification
tools to correct for any process temperature effect.
■
For density measurement, process temperature effect is defined as the change in density accuracy specification due to process
temperature change away from the calibration temperature.
— For all models, process temperature effect on density is ±0.000015 g/cm³ (±0.015 kg/m³) per degree difference from
calibration temperature.
— For models ordered with optional temperature calibration, density specification is valid from 0 °F (-17.8 °C) to 60 °F (15.6 °C)
and process temperature effect should be considered when operating above or below this range.

Two-phase flow effect
NAMUR NE 132 guidelines state that, “Coriolis meters with a higher agitation frequency react more sensitively to gas bubbles in
liquids when compared to devices with a lower agitation frequency.” For operating (agitation) frequency ranges for each model,
see Best practices: installing and selecting meters for two-phase flow.
Two-phase flow effects are governed by an increased decoupling ratio or a decreased Velocity of Sound (VoS) in the process fluid
due to entrained gas, aeration, or the presence of liquid in gas. Following best practices regarding installation and meter selection
can prevent or minimize measurement errors associated with two-phase flow effects.
Tip
For more details regarding the effects of two-phase flow on Coriolis meters, or performance expectations in these applications, see
the Entrained Gas Handling in Micro Motion Coriolis white paper and any additional resources available at www.emerson.com/
flowmeasurement.
Performance influences during two-phase flow conditions
Optimal meter performance during two-phase flow conditions is primarily governed by meter selection, flow regime, and fluid
properties. Sample magnitudes of the effect are provided in the white paper referenced previously. The information in the
following table provides common forms of influence quantities that can affect measurement performance during two-phase flow
conditions.

See Operating drive mode frequency range for all models.
Select a meter that operates in an ULTRA-
(1)
LOW
or LOW drive frequency range to
avoid VoS effects.
Increase fluid viscosity, decrease bubble
size, or use a meter with lower drive
frequency in order to minimize
decoupling.
Select advanced electronics that use
high-speed mass and density signal
processing methods for effective noise
rejection.
Best practices: installing and selecting meters for two-phase flow
Flow sensor best practices:
■
Ensure that the meter is sized correctly to maintain a flow rate greater than 5:1 turndown from nominal.
■
Install the meter with the preferred orientation. For orientation based on fluid type, see the Micro Motion ELITE Coriolis Flow and
Density Sensors Installation Manual
■
Select a meter design with the lowest available operating frequency.
Transmitter and electronics best practices:
■
Enable multiphase severity alerts to accurately detect when two-phase flow is present.
■
Select a meter with a real-time clock and historian capabilities to diagnose process events or upsets.
■
Use Advanced Phase Measurement in intermittent high %GVF or %LVF installations where density or volume flow is required.
