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 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.

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, contact customer service.
■
The letter at the end of the base model code (for example R100S) represents wetted part material and/or application
designation: S = stainless steel and P = high pressure. Detailed information about the complete product model codes are
described later in this document.
Performance specifications
Reference operating conditions
For determining the performance capabilities of our meters, the following conditions were observed/utilized:

Gas flow rates
When selecting sensors for gas applications, pressure drop 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 you either refer to www.emerson.com/flowmeasurement or contact customer service for more information.
The below table indicates flow rates that produce approximately 25 psig (1.72 barg) pressure drop on natural gas.

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 below. 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.

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.
■
Temperature limits may be further restricted by hazardous area approvals. Refer to the hazardous area approvals
documentation shipped with the sensor or available at www.emerson.com/flowmeasurement.
■
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)), please ensure electronics are not enclosed in insulation as this may lead to electronics
failure.

Process temperature effect
■
For mass flow measurement, process temperature effect is defined as the change in sensor flow accuracy due to process
temperature change away from the calibration temperature. Temperature effect can be corrected by zeroing at the process
conditions.

Pressure relief
R-Series sensors are available with a rupture disk installed on the case. Rupture disks are meant to vent process fluid from the
sensor case in the unlikely event of a flow tube breach. Some users connect a pipeline to the rupture disk to help contain escaping
process fluid. For more information about rupture disks, contact Micro Motion Customer Service.
If the sensor has a rupture disk, it should remain installed at all times as it would otherwise be necessary to re-purge the case. If the
rupture disk is activated by a tube breach, the seal in the rupture disk will be broken, and the Coriolis meter should be removed
from service.
The rupture disk is located as follows on the meter, and the warning sticker shown is placed next to it.
DANGER
Stay clear of the rupture disk pressure relief area. High-pressure fluid escaping from the sensor can cause severe injury or
death.
The sensor must be oriented so that personnel and equipment will not be exposed to any discharge along the pressure relief path.
Important
If a rupture disk is used, the housing can no longer assume a secondary containment function.
WARNING
Removing the Purge Fitting, Blind Plug, or Rupture Disks compromises the Ex-i Safety Certification, the Ex-tc Safety
Certification, and the IP-rating of the Coriolis meter. Any modification to the Purge Fitting, Blind Plug, or Rupture Disks
must maintain a minimum of IP66/IP67 Ratings.
