Communication standards
2.2Communication standards
Switches and jumpers on the transmitter determine the communication
standard used by the transmitter. Micro Motion configures each
transmitter's default communication settings at the factory.
Depending on the transmitter model, transmitters can communicate
using HART and/or Modbus
®
protocol, using the Bell 202 or RS-485
standard. Communication configuration for the ProLink program and
transmitter must be the same.
Factory-default settings
The factory default settings for Version 3 RFT9739 transmitters are:
•HART protocol over the Bell 202 standard at 1200 baud, 1 stop bit,
odd parity
•Modbus protocol over the RS-485 standard at 9600 baud, 1 stop bit,
odd parity
The factory default settings for the IFT9701, IFT9703, RFT9712, and
RFT9729 are: HART protocol over the Bell 202 standard at 1200 baud, 1
stop bit, odd parity.
User configuration
Transmitter models RFT9739, RFT9712, and RFT9729 can be
reconfigured for user-defined communication settings using switches
and jumpers on the transmitter. To establish a user-defined
communication configuration, see the transmitter instruction manual.
®
HART
and Modbus® communication
The primary variable milliamp output on the RFT9739, and the 4-20 mA
output on the IFT9701, IFT9703, RFT9712, and RFT9729 can produce
HART-compatible signals for Bell 202 communication.
Micro Motion transmitters can function as part of a Bell 202 or RS-485
multidrop network.
•The RFT9739 can use the Bell 202 or RS-485 standard under HART
protocol, or the RS-485 standard under Modbus protocol.
•The IFT9701 and IFT9703 can use the Bell 202 standard under
HART protocol only.
•The RFT9712 and RFT9729 can use the Bell 202 or RS-485
standard under HART protocol only.
Up to 15 transmitters can participate with other devices in a Bell 202
multidrop network. Each transmitter must have a unique polling address
of 1 to 15, or a unique tag name.
Up to 32 transmitters can participate in an RS-485 multidrop network.
Each transmitter must have a unique tag name; up to 15 transmitters
may have unique polling addresses from 1 to 15. The IFT9701 and
IFT9703 cannot communicate in an RS-485 network.

Rate dialog box
Update Rate controls how often the ProLink program prints tickets and
updates on-line values of variables displayed in the View windows. See
Chapter 6
•The Window Update Rate is the number of seconds the program
waits before updating values displayed in the View windows.
•The Ticket Print Rate is the number of seconds the program waits
between each interval print.
The update rate is dependent on selected communication options such
as baud rate, computer performance, and number of parameters polled.
Therefore, the rate entered is a "minimum" value. The maximum value
that can be entered is 86,400 (equal to 24 hours).
Open the File menu, then choose Update Rate. The Update Rate dialog

•Downscale: milliamp outputs go to 0 mA if they produce a 0-20 mA
current, or to 0-2 mA if they produce a 4-20 mA current;
frequency/pulse output goes to 0 Hz.
•Upscale: milliamp outputs go to 22-24 mA; frequency/pulse output
goes to 15-19 kHz.
•Last measured value (not available with V ersion 3 transmitters):
Outputs hold the values measured immediately before the fault
condition occurred.
•Internal zero (not available with Version 3 transmitters): Outputs
indicate a value of zero for the represented process variable.

To troubleshoot these status indicators, follow these steps:
1. Wiring problems are often incorrectly diagnosed as a faulty sensor.
At initial startup of the transmitter, alwa ys check the following:
a. Proper cable, and use of shielded pairs
b. Proper wire termination
•Wires on correct terminals
•Wires making good connections at transmitter terminals
Table 7-2
(
lists terminal designations for Micro Motion
sensors)
•Wires properly connected at any intermediate terminal
junction, such as the junction box between a Model DT sensor
and transmitter
2. For a Version 3 RFT9739, follow steps 2a through 2b. For earlier
versions, and for other transmitter models, go to step 3.
a. Open the Test menu, then choose Test Points. The Test Point
Diagnostics dialog box appears, as depicted in
Figure 7-4

Analog Input Error applies only to versions 2.0 and higher RFT9739
transmitters. Analog Input Error switches ON when the pressure input to
the RFT9739 is less than 4 mA or greater than 20 mA, and indicates one
of the following conditions:
•Faulty wiring between a pressure transmitter and the RFT9739
•Pressure input requires characterization
Pressure Input Failure applies only to RFT9739 transmitters with

If Analog Input Error or the Pressure Input Failure switches ON:
•Characterize range limits for milliamp input
•Check for faulty wiring to or from pressure transmitter
•Alter fluid process
Data Loss Possible switches ON when a power fluctuation occurs during

"Slug Flow"
Programmed slug flow limits enable transmitter outputs and the ProLink
Status window to indicate conditions such as slug flow (gas slugs in a
liquid flow stream or liquid in a gas stream). Such conditions adversely
affect sensor performance by causing erratic vibration of the flow tubes,
which in turn causes the transmitter to produce inaccurate flow signals.
If the fluid density goes outside the user-defined slug flow limits, all of
the following occur:
•The Slug Flow indicator in the ProLink Status window switches ON.
•Milliamp outputs go to 0 mA if they produce a 0-20 mA current, or to
4 mA if they produce a 4-20 mA current.
•Frequency/pulse output goes to 0 Hz.
•Flow totalization stops while the density reading is outside density
limits.
•The diagnostic LED on RFT9739 field-mount, IFT9701, IFT9703 ,
and RFT9712 transmitters blink OFF once per second (75% ON,
25% OFF).
•The flowmeter resumes normal operation when liquid fills the flow
tubes (when density stabilizes within the programmed slug flow
limits).

In some applications, slug flow typically occurs for short periods of time.
If slug flow ceases in less than one minute, an RFT9739 can continue
holding the last accurately measured flow value until process density
stabilizes within the programmed slug flow limits. A user-defined slug
duration specifies the amount of time the RFT9739 indicates the last

8.2Flow calibration factor
Sensor and transmitter
shipped together
The flow calibration factor describes a particular sensor's sensitivity to
mass flow. Testing conducted in the Micro Motion flow calibration
laboratory determines the precise value of the flow calibration factor for
each sensor. (For an RFT9739, IFT9701, IFT9703, RFT9712, or
RFT9729 that is shipped without a sensor, the default value — which
must be changed — is 1.00005.13).
The first five digits and first decimal point
are the flow rate, in grams
per second, required to produce one microsecond of time shift between
velocity signals transmitted by sensor pickoff coils. In the default
calibration factor above, the first five digits and first decimal point
indicate that, for every detected microsecond of time shift, 1.0000 grams
of fluid per second flow through the sensor.
The last three digits and second decimal point
represent the
temperature coefficient for the sensor. The temperature coefficient
represents the percent change in the rigidity of the flow tubes around the
twisting axis per 100
°
C.
If the sensor and transmitter were ordered together as a Coriolis
flowmeter, the correct flow calibration factor was programmed into the
transmitter at the factory and does not need to be changed.

8.3Density factors for
RFT9739
Density factors describe a particular sensor's density measurement
sensitivity. Testing conducted in the Micro Motion Flow Calibration
Laboratory determines the precise values of the density factors for each
sensor.
The RFT9739 uses six separate factors to calculate density:
Dens A
•
is the density, in grams per cubic centimeter, at line
conditions, of the low-density material used during a two-point
density calibration.
Dens B
•
is the density, in grams per cubic centimeter, at line
conditions, of the high-density fluid used during a two-point density
calibration.
K1
•
is the tube period, in microseconds, adjusted to 0
°
C, when the
flow tubes contain the Dens A calibration fluid at line conditions.
K2
•
is the tube period, in microseconds, adjusted to 0
°
C, when the
flow tubes contain the Dens B calibration fluid at line conditions.
FD
•
(or
K3)
accounts for the effect of high flow rate on the density
measurement, and usually is not required. The FD and K3 factors
can be stored in, and viewed from, the ProLink transmitter
configuration file. The FD or K3 density calibration procedure is
described in

Density characterization
for RFT9739
If the sensor and transmitter were ordered together as a Coriolis
flowmeter, they are factory calibrated. No additional characterization or
calibration is necessary. Characterization is required if either the sensor
or RFT9739 is replaced.
If the sensor or RFT9739 is replaced in the field, the user must
re-characterize the sensor by programming new density factors into the
transmitter.
CAUTION
Improper density characterization could cause
density and volume measurement error.
Density characterization resets the third density
calibration factor (K3) for the RFT9739. For sensors
manufactured after October 1997, a new FD
calibration factor is provided on serial number tags
and calibration certificates.
For RFT9739 transmitters only, perform a third-point

8.5Slug flow limits
Slug flow limits enable detection of conditions such as slug flow (such as
gas slugs in a liquid flow stream, or liquid in a gas/air flow stream).
•If fluid density goes outside a slug flow limit, all of the following occur:
•The Slug Flow indicator in the ProLink Status window switches ON
•The frequency/pulse output goes to 0 Hz
•Milliamp outputs indicating flow go to a level that corresponds to a
zero flow condition
•Flow totalization stops while density reading is outside slug flow
limits
•On field-mount transmitters, the diagnostic LED blinks once per
second (75% ON, 25% OFF)
To establish slug flow limits, enter values in grams per cubic centimeter
(g/cc), regardless of the density units established for density as a
transmitter variable.
The RFT9739 offers an additional slug flow parameter, slug duration,
which is described in

8.6Temperature factor for
RFT9739
Vaporization of the process liquid sometimes causes slug flow in a
liquid flow stream in which the density of the liquid should remain
above 0.9000 grams per cubic centimeter (g/cc).
To detect density below the specified density of the process liquid due
to vaporization, set the low slug flow limit at a density above 0.9000
g/cc. Such a setting will cause the transmitter to indicate slug flow
when the process density goes below the specified limit for the liquid.
Temperature characterization (calibrating the flowmeter for temperature)
is not recommended.
CAUTION
Temperature characterization will cause
measurement error.
Temperature characterization affects the RFT9739
flow and density and will require completely
recalibrating the flowmeter for flow, density, and
viscosity measurement.
Temperature characterization of the RFT9739 is not
recommended.
For an RFT9739, the temperature calibration factor describes the slope

represents the temperature of the sensor flow tubes. In a Micro Motion

Real-time compensation
A Version 2 or Version 3 RFT9739 can compensate for the effect of
pressure on sensor flow tubes. Pressure effect is defined as the change
in sensor flow sensitivity due to process pressure change away from
calibration pressure. Sensors that are affected by pressure are listed in

In applications where the operating pressure varies significantly from the
pressure at which the flowmeter was calibrated, the user can establish
pressure compensation. Pressure effect can be corrected in one of two
ways:
•For real-time compensation, by entering pressure correction factors
•For relatively stable operating pressures, by adjusting the calibration
For real-time pressure compensation, two pressure compensation
factors must be entered, one for flow and one for density . In the FlowF act

In addition, real-time pressure compensation requires either gauge
pressure or analog pressure input. (To select an input for pressure
compensation, see
Gauge pressure input
If a pressure transmitter connected to a host controller measures gauge
pressure at the sensor input, the RFT9739 can use flow and densi ty
signals from the sensor, and pressure signals from the host controller, to
compensate for the pressure effect on the sensor.
•In a HART-compatible network, the RFT9739 functions as a primary
or secondary master while polling the host controller.
•In a Modbus-compatible network, the host controller downloads
pressure values to register 40007 or register pair 20257-20258.
Analog pressure input
The RFT9739 can be connected to an analog pressure transmitter that
produces a 4-20 mA input signal representing pressure. The RFT9739
or an external source can power the pressure transmitter.
•To connect a pressure transmitter to the RFT9739, see the RFT9739
instruction manual.
•If a sensor is ordered for an application requiring pressure
compensation, the pressure input is configured at the factory.
