2 RFT9739 Transmitter

RFT9739 transmitter

The RFT9739 transmitter works with Micro Motion ® sensors to provide precision fluid measurement in a wide variety of fluid applications. The RFT9739 has modular, microprocessor-based electronics, incorporating ASIC digital technology with a choice of digital communication protocols.

Combined with a Micro Motion sensor, the RFT9739 provides accurate mass flow, density, temperature, and volumetric measurements of process fluids.

With a pressure transmitter properly installed in the flow loop, the transmitter also indicates pressure.

The RFT9739 simultaneously transmits four output signals. Two independently configured analog outputs can each indicate flow rate, density, temperature, or pressure. A frequency/pulse output indicates flow rate or total. A control output indicates flow direction, a fault, or flowmeter zero in progress.

The RFT9739 is available in field-mount and rackmount versions. The field-mount transmitter is housed in a IP65 (NEMA 4X) explosion-proof enclosure that provides easy access to the electronics module, and allows the transmitter and sensor to be installed in the same hazardous area.

The rack-mount transmitter's compact housing is ideal for control room installations.

The RFT9739 features user-selected Bell 202 or

RS-485 serial standard for HART ® or Modbus ® communication protocols. For configuration in the field, use Micro Motion ProLink ® software,

Fisher-Rosemount ä AMS software, or a Rosemount ®

Model 275 HART Communicator.

An integral liquid crystal display (LCD) is standard on the rack-mount model, optional with the field-mount version. Use the display to set communication parameters, read process variables, reset flow totalizers, and view diagnostic messages.

Choose from a wide range of sensors to suit your application. The RFT9739 is compatible with

Micro Motion ELITE ® sensors, the most accurate

Coriolis meters available today. Or choose

Micro Motion F-Series sensors, standard or high-pressure Model D sensors, Model DT hightemperature sensors, or Model DL sanitary sensors.

Model RFT9739 transmitters support PlantWeb ä field-based architecture, a scalable way to use open and interoperable devices and systems to build process solutions of the future.

Frequency

One frequency/pulse output can be configured to indicate mass flow rate, volumetric flow rate, mass total (inventory), or volume total (inventory), independent of analog outputs.

Internally powered, 0-15 V square wave, unloaded;

2,2 kohm impedance at 15 V, galvanically isolated to

± 50 VDC. In open collector configuration: sinking capability,

0,1 amps in “on” condition (0 volt level), 30 VDC compliance in “off” condition. Signal can be scaled up to 10000 Hz.

Out-of-range capability to 15000 Hz. Programmable pulse width for low frequencies.

Dual-channel frequency (rack-mount transmitter only)

Approved for custody transfer applications, a dual-channel frequency output, referred to as frequency A and frequency B.

Phase shift between channels is 90 degrees. Output derived from the primary frequency, and represents the same process variable as the frequency output, but with half the frequency. All specifications match frequency/pulse output except: Signal can be scaled up to 5000 Hz; out-of-range capability to 7500 Hz. The output complies with

VDE/VDI 2188.

Optocoupler (rack-mount transmitter only)

The optocoupler is an externally powered output. Signal voltage: low level 0-2 VDC, high level 16-30 VDC. Maximum signal current 0,01 amp. Maximum capacitive load 150 nF at

10 kHz. Output is derived from the primary frequency, and represents the same process variable as the frequency/pulse output. The output complies with

VDE/VDI 2188.

Control

One control output can represent flow direction, fault alarm, zero in progress, event 1 or event 2. Internally powered, digital level, 0 or 15 V, 2,2 kohm pull-up, galvanically isolated to ± 50 VDC. In open collector configuration: sinking capability, 0,1 amps in “on” condition (0 volt level),

30 VDC compliance in “off” condition.

Minimum 4-20 mA span: 10° API.

Standard volume

Indicates standard volume at 60°F or 15°C for Generalized

Petroleum Products when °API is selected as density unit of measure. Accuracy of standard volume measurements depends on accuracies of mass flow rate, density, temperature and temperature-corrected °API calculation, and can be estimated using the root mean square method.

Standard volume accuracy of ± 0,5% of rate is typically attainable for Generalized Petroleum Products such as fuel oils, jet fuels, and kerosenes.

Pressure compensation

Analog input can accept a signal from a pressure transmitter for pressure compensation of flow and density.

Range, 0-25 mA. Can be used to power independent pressure or differential pressure transmitter. Voltage sourcing capability, 15 V. Input impedance, 100 ohms.

Low-flow cutoff

Flow values below the low-flow cutoff cause analog, frequency, and digital outputs to default to zero flow levels.

Each mA output may be configured for an additional low-flow cutoff.

Slug-flow limits

Transmitter senses density outside limits. Flow output remains at last measured value, for a programmed time of

0-60 seconds, before defaulting to the level that represents zero flow.

Damping

Wide range of programmed filter time constants for damping on flow, density, and temperature. Additional damping may be applied to mA outputs.

Fault indication

Faults can be indicated by user-selected downscale

(0 mA or 0-2 mA, 0 Hz) or upscale (22,2-24 mA, 15-19 kHz) output levels. Control output can also be configured to indicate a fault condition at 0 V.

Output testing

Current source

Transmitter can produce a specified current between

0 and 22 mA on 0-20 mA output, or between 2 and 22 mA on 4-20 mA output.

Frequency source

Transmitter can produce a specified frequency between

0,1 and 15000 Hz.

Local display

Optional for field-mount transmitter. Standard on rack-mount transmitter. Display is a 2-line, 16-character, alphanumeric liquid crystal display (LCD).

Using the transmitter's scroll function, the user can view flow rate, density, temperature, mass and volume totals and inventory levels, and status messages on the LCD.

A reset button allows the user to reset the transmitter's flow totalizers and communication parameters, as well as zero the flowmeter.

Environmental effects

EMI effect on sensor and transmitter

Transmitters with enhanced EMI immunity meet the requirements of the EMC directive 89/336/EEC per

EN 50081-1 (January 1992) for field-mount RFT9739,

EN 50081-2 (January 1992) for rack-mount RFT9739, and

EN 50082-2 (March 1995), when operated at nominal rated flow measurement range. Enhanced EMI immunity is required for transmitters installed in the European

Community after 1 January 1996.

For specific EMC effects within the EC, the Technical EMC file may be reviewed at Micro Motion Veenendaal.

All RFT9739 transmitters meet the requirements of

SAMA PMC 33.1 (October 1978), Class 1, A, B, C

(0,6% span) at nominal flow rate. All RFT9739 transmitters meet the recommendations of ANSI/IEEE C62.41 (1991) for surge and EFT.

To meet the above specifications, the transmitter must be installed with an approved Micro Motion sensor, and the sensor cable must be either doubly shielded with full contact glands, or installed in continuous, fully bonded, metallic conduit. The transmitter and sensor must be directly connected to a low-impedance (less than 1 ohm) earth ground. Transmitter outputs must be run in standard twisted-pair, shielded instrument wire.
