Other Multivariable Applications
Most multivariable transmitters are
used in flow applications.
However, there are other
applications which require that
multiple process variables (DP, AP
and T) be transmitted to a control
system - DCS or PLC. It is in the
control system where a calculation
such as compensated level for
liquid level applications or complex
calculations to infer composition in
distillation columns are performed.
A SMV 3000 in these applications
can save substantial wiring,
installation and purchase costs
versus 2 or 3 separate single-
variable transmitters. Whether
integrating digitally to a TDC/TPS
3000 Control System or providing
4 analog 1-5 V outputs to a PLC or
DCS via the MVA Multivariable
Analog Card, the SMV 3000 is
very cost effective in multivariable
applications.
Smart Technology Delivers Broad Benefits and Reduces Total Cost of Ownership
The SMV 3000 combines
integrated sensor and
microprocessor technologies as
well as dynamic flow
compensation to produce the most
accurate and consistent
measurement possible, and is
based on ST 3000 technology
which is the most reliable in the
industry. These features help
improve product yield, increase
process efficiency and enhance
plant safety.
In addition to the advantages of
superior accuracy and reliability,
the SMV 3000 Smart Multivariable
Flow Transmitter significantly
lowers your lifetime cost of
ownership in several ways:
•
Installation - Wiring cost
savings are achieved, as well
as reduced costs of piping,
manifolds, mounting, safety
barriers, etc., with the SMV
Smart Configuration Flexibility
Like other Smartline Transmitters,
the SMV 3000 features two-way
communication between the
operator and the transmitter via the
SCT 3000 Smart Configuration
Toolkit or SFC - Smart Field
Communicator. You connect the
SFC or SCT anywhere that you can
access the transmitter signal lines.
Communicators provide the
capabilities of transmitter
adjustments and diagnostics from
remote locations, such as the
control room. The SFC and SCT
support other Smartline Instruments
too: ST 3000, STT 3000 and
MagneW Plus.
Smart Field Communicator
3000 due to its unique ability
tomeasure both differential and
static pressure with a single
sensor, and Process
Temperature with an external
RTD or thermocouple.
By dynamically calculating the
compensated mass flow, the
SMV 3000 totally eliminates
the need for a dedicated flow
computer, or it can free your
control system from performing
this function.
•
Commissioning - The Hand-
held SFC III Smart Field
Communicator or SCT 3000
Smart Configuration Toolkit
lets a single technician
remotely configure SMV 3000
Smart Multivariable Flow
Transmitters and re-range
them when application
requirements change. The
SCT must be used to
configure the advanced flow
parameters.
The SCT 3000 has an advantage
over the SFC in that it can also be
used to configure the complete
SMV 3000 database and save this
database for later access. The
SCT 3000 is a software package
which runs on an IBM compatible
computer utilizing the Windows 95,
Windows 98 or Windows NT
platforms. The SCT 3000 must be
used to configure the advanced
flow parameters for the SMV 3000.
•
Maintenance - The SMV 3000
offers greater accuracy and
stability, reducing the
frequency of calibration. Self-
diagnostics can automatically
indicate impending problems
before they affect reliability or
accuracy. Also, a single
technician can diagnose
problems remotely, using the
SFC, SCT 3000 or TPS Global
User Station, saving time and
reducing cost. The SMV
3000 also provides improved
reliability with a single device
replacing up to three
transmitters.
•
Inventory stocking -
Enhanced reliability, combined
with the high turndown
capability of the SMV 3000,
reduces the quantity of
instruments needed to stock
as backups for the installed
transmitters.
