1.3 SMV 3000 Smart Multivariable Transmitters

About the Transmitter

The SMV 3000 Smart Multivariable Transmitter shown in Figure 1
measures three separate process variables and calculates volumetric or
mass flow rate for gases, steam or liquids for output over a 4 to 20
milliampere, two-wire loop. Its general design is based on the field proven
technology of our ST 3000 Smart Pressure Transmitter and meets the
same high performance standards.

Figure 1 SMV 3000 Transmitter Handles Multiple Process Variable

Measurements and Calculates Flow Rate

Electronics
Housing

Meter body

The SMV 3000 transmitter accepts process temperature signals from an
external Resistance Temperature Detector (RTD) or any one of several
common thermocouple types. Its unique measurement sensor
simultaneously handles differential pressure, static pressure, and meter
body temperature signals while a separate circuit processes the process
temperature input. Note that the static pressure (absolute or gauge) is read
from the high pressure side of the meter body.

Using stored equations in conjunction with the multiple process variable
inputs, the SMV 3000 calculates a compensated volumetric or mass flow
rate output for gases, liquids and steam. Its output signal is proportional to
the calculated differential flow rate.

1.3 SMV 3000 Smart Multivariable Transmitters, Continued

SMV Operating Modes

The SMV 3000 can transmit its output in either an analog 4 to 20
milliampere format or a Digitally Enhanced (DE) protocol format for
direct digital communications with our TPS/TDC 3000 control system. In
the analog format, only a selected variable is available as an output which
can be any one of the following:

• Differential Pressure PV1,

• Static Pressure PV2,

• Process Temperature PV3, or

• Calculated Flow Rate PV4

Note that the secondary variable is only available as a read only parameter
through the SCT or SFC. See Figure 2.

adjustments

The SMV 3000 transmitter has no physical adjustments. You need an SCT
to make any adjustments in an SMV 3000 transmitter. Alternately, certain
adjustments can be made through the Universal Station if the transmitter is
digitally integrated with our TPS/TDC 3000 control system.

1.5 Smart Field Communicator (SFC)

About SFC
Communications

The portable, battery-powered SFC serves as the common communication
interface device for Honeywell’s family of Smartline Transmitters. It
communicates with a transmitter through serial digital signals over the 4 to
20 milliampere line used to power the transmitter. A request/response
format is the basis for the communication operation. The transmitter’s
microprocessor receives a communication signal from the SFC, identifies
the request, and sends a response message.

Figure 5 shows a simplified view of the communication interface provided
by an SFC.

ATTENTION

Because of the advanced capabilities built-in to the SMV 3000, we do not
recommend that you use the SFC to configure the SMV transmitter. Some
of the SMV’s advance functions are not supported by the SFC. Although
you can use the SFC to perform certain operations, such as calibrate or re­range the transmitter, read transmitter status and diagnose faults.

Using the SFC with
the SMV 3000

If you use the SFC to communicate with the SMV, you can adjust
transmitter values, or diagnose potential problems from a remote location
such as the control room. You can use the SFC to:

• Monitor: Read the input pressure, process temperature, or

secondary variable to the transmitter in engineering
units.

• Display: Retrieve and display data from the transmitter or SFC

memory.

ATTENTION

Precautions for
Mounting
Transmitters with
Small Differential
Pressure Spans

The mounting position of an SMV 3000 Transmitter is critical as the
transmitter spans become smaller for the absolute and/or differential
pressure range. A maximum zero shift of 0.048 psi for an absolute
pressure range or 1.5 in H

O for a differential pressure range can result

2

from a mounting position which is rotated 90 degrees from vertical. A
typical zero shift of 0.002 psi or 0.20 in H

O can occur for a 5 degree

2

rotation from vertical.

To minimize these positional effects on calibration (zero shift), take the
appropriate mounting precautions that follow for the given pressure range.

• For a transmitter with a small differential pressure span, you must

ensure that the transmitter is vertical when mounting it. You do this by
leveling the transmitter side-to-side and front-to-back. See Figure 9 for
suggestions on how to level the transmitter using a spirit balance.

• You must also zero the transmitter by adjusting the mounting position

of the transmitter. Refer to start-up procedure in Section 7 for SMV
3000 transmitter model SMA110 and transmitters with small
differential pressure spans.

4.3 Piping SMV 3000 Transmitter

Summary

The actual piping arrangement will vary depending upon the process
measurement requirements. Process connections can be made to standard
1/4-inch NPT female connections on 2-1/8 inch centers in the double­ended process heads of the transmitter’s meter body. Or, the connections
in the process heads can be modified to accept 1/2 inch NPT adapter
flange for manifolds on 2, 2-1/8, or 2-1/4 inch centers

The most common type of pipe used is 1/2 inch schedule 40 steel pipe.
Many piping arrangements use a three-valve manifold to connect the
process piping to the transmitter. A manifold makes it easy to install and
remove a transmitter without interrupting the process. It also
accommodates the installation of blow-down valves to clear debris from
pressure lines to the transmitter.

Figure 10 shows a diagram of a typical piping arrangement using a three­valve manifold and blow-down lines for a flow measurement application.

Transmitter location

The suggested mounting location for the transmitter depends on the
process to be measured. Figure 11 shows the transmitter located above the
tap for gas flow measurement. This arrangement allows for condensate to
drain away from the transmitter.

Figure 12 shows the transmitter located below the tap for liquid or steam
flow measurement. This arrangement minimizes the static head effect of
the condensate. Although the transmitter can be located level with or
above the tap, this arrangement requires a siphon to protect the transmitter
from process steam. (The siphon retains water as a “fill fluid.”)

ATTENTION

For liquid or steam, the piping should slope a minimum of 25.4 mm (1
inch) per 305 mm (1 foot). Slope the piping down towards the transmitter
if the transmitter is below the process connection so the bubbles may rise
back into the piping through the liquid. If the transmitter is located above
the process connection, the piping should rise vertically above the
transmitter; then slope down towards the flow line with a vent valve at the
high point. For gas measurement, use a condensate leg and drain at the
low point (freeze protection may be required here).

General piping
guidelines

ATTENTION

• When measuring fluids containing suspended solids, install permanent

valves at regular intervals to blow-down piping.

• Blow-down all lines on new installations with compressed air or steam

and flush them with process fluids (where possible) before connecting
these lines to the transmitter’s meter body.

• Be sure all the valves in the blow-down lines are closed tight after the

initial blow-down procedure and each maintenance procedure after that.

Table 6 gives the steps for installing an optional 1/2 inch NPT flange
adapter on the process head.

Slightly deforming the gasket supplied with the adapter before you insert it
into the adapter may aid in retaining the gasket in the groove while you
align the adapter to the process head. To deform the gasket, submerse it in
hot water for a few minutes then firmly press it into its recessed mounting
groove in the adapter.

Summary, continued

You connect RTD leads to the TC terminals 1, 2, 3, and 4 as appropriate
for the given probe type.

You connect thermocouple leads to terminals 1 (–) and 3 (+), observing
polarity.

Each transmitter includes an internal ground terminal to connect the
transmitter to earth ground or a ground terminal can be optionally added to
the outside of the electronics housing. While it is not necessary to ground
the transmitter for proper operation, we suggest that you do so to minimize
the possible effects of “noise” on the output signal and provide additional
protection against lightning and static discharge damage. Note that
grounding may be required to meet optional approval body certification.
Refer to section 1.2 CE Conformity (Europe) Notice for special
conditions.

Transmitters are available with optional lightning protection if they will be
used in areas highly susceptible to lightning strikes.

Barriers must be installed per manufacturer’s instructions for transmitters
to be used in intrinsically safe installations (see control drawing 51404251

The SMV 3000 transmitter can be equipped with an optional analog
output meter.

The analog meter provides a 0 to 100% indication of the transmitter’s
output through traditional pointer and scale indication. It can be mounted
integrally on top of the terminal block in the electronics housing with a
meter end cap or remotely in a separate housing.

You connect the analog meter across the meter terminals on the terminal
block with the metal jumper strap removed. For more detailed information
on wiring the analog meter, refer to control drawing 51404251 (for
intrinsically safe installations) and external wiring diagrams 51404250 and
51404251 (for non-intrinsically safe installations) in Section 13.

Off-line Configuration
Procedures

SCT Hardware
Connections

The SCT 3000 allows you to perform both off-line and on-line
configuration of SMV transmitters.

• Off-line configuration does not require connection to the transmitter.

By operating the SCT 3000 in the off-line mode, you can configure
database files of an unlimited number of transmitters prior to receipt,
save them either to hard disk or a floppy diskette, and then download
the database files to the transmitters during commissioning.

• An on-line session requires that the SCT is connected to the transmitter

and allows you to download previously-configured database files at
any time during installation or commissioning of your field
application. Note that you can also upload a transmitter’s existing
configuration and then make changes directly to that database.

Refer to the SCT User Manual (on-line) for detailed procedures on how to
off-line configure SMV transmitters using the SCT 3000.

A PC or laptop computer (host computer) which contains the SCT
software program, is connected to the wiring terminals of the SMV
transmitter and other smart field devices. Figure 18 shows the hardware
components of the SCT.

Write Protect Option

The SMV 3000 transmitters are available with a “write protect option”. It
consists of a jumper located on the transmitter’s Main Printed Circuit
Board (PCB) under the temperature measurement (Daughter) PCB that
you can position to allow read and write access or read only access to the
transmitter’s configuration database. When the jumper is in the read only
position, you can only read/view the transmitter’s configuration and
calibration data. Note that the factory default jumper position is for read
and write access. There is no need to check jumper position unless you
want to change it.

6.2 Overview

About Configuration

Each SMV 3000 Transmitter includes a configuration database that
defines its particular operating characteristics. You use the SCT 3000 to
enter and change selected parameters within a given transmitter’s database
to alter its operating characteristics. We call this process of viewing and/or
changing database parameters “configuration”.

SMV configuration can be done using the SCT either on-line, where
configuration parameters are written to the SMV through a direct
connection with the SCT, or off-line where the transmitter configuration
database is created and saved to disk for later downloading to the SMV.
Figure 20 shows a graphic summary of the on-line configuration process.

SMV 3000 /SCT
Connections

SFC and SMV 3000
Configuration

When using a Honeywell-defined SMV template, you should choose a file
template for the temperature range and model of SMV that you wish to
configure.

For example, if the SMV transmitter is a model SMA125 and you are
using a J-type thermocouple as the process temperature PV3 input, you
would choose the template file sma125j.hdt from the list of Honeywell
templates. You would then enter the configuration parameters in the
fields of the tab cards displayed in the SCT window.

Configuration is complete when you have entered all parameters in the
template’s tab cards, (and for flow applications you have entered all flow
data in the flow compensation wizard). You then save the template file
containing the SMV transmitter’s database as a disk file.

Refer to Section 5.2 Establishing Communications or the SCT on-line user
manual for connecting the SCT and SMV for on-line configuration.

We do not recommend that you configure the SMV using the Smart Field
Communicator (SFC). Some of the advanced functions of the SMV
transmitter are not supported by the SFC. However you can use the SFC
to perform certain operations, such as calibrate or re-range the transmitter,
read transmitter status and diagnose faults.

SMV 3000 Transmitter User’s Manual 1/9948

6.3 Configuring the SMV 3000 with The SCT

Using the SCT for
SMV 3000
Configuration

The SCT template files have tab cards that contain data fields for the SMV
parameters which you fill in. You start with the Device tab card to enter
the device tag name (Tag ID) and other general descriptions. Next, you
can select each tab card in order and configure each PV (PV1, secondary
variable if desired, PV2, PV3, and PV4).

SMV Process Variable SCT Template Tab Card

PV1 (Differential Pressure) DPConf
PV2 (Absolute Pressure or APConf or GPConf *

Gauge Pressure) *
PV3 (Process Temperature) TempConf
PV4 (Flow) FlowConf

* PV2 will be AP of GP depending on SMV model

Use the Flow Compensation Wizard to setup the SMV 3000 for flow
applications. The flow wizard guides you through the steps necessary to
complete your flow configuration. See Subsection 6.10 and Appendix C
for more information about the flow wizard.

ATTENTION

In the subsections below information is given for filling in some of the
SCT tab card data fields. Supplementary background information and
reference data on SMV configuration that may be helpful is also
presented. Use the SCT on-line help and user manual for detailed “how to
configure” information.

If the transmitter detects an incomplete database upon power-up, it will
initialize the database parameters to default conditions. A setting or

selection with a superscript “d” in the following subsections identifies the
factory setting.

6.4 Device Configuration

Transmitter Tag Name
and PV1 Priority

Background

Tag ID field is found on the Device tab card.

Tag ID - Enter an appropriate tag name for the transmitter containing up
to eight ASCII characters which uniquely identifies the transmitter.

NOTE: It is suggeste d that when you create a database co nfiguration file fo r the

transmitter, you make the file name the same as the transmitter tag ID.

PV1 Priority - Enter “/ ” slash as the eighth character in tag number to set
PV1 as “priority” PV in DE (digital) data broadcast, if all four PVs are
selected for broadcast (turned ON). See “Selecting PVs for Broadcast” on
next page for an explanation on the broadcast of PVs.

Normally, PV1 has the number 1 priority unless all four PVs are selected
for broadcast. Then, PV4 has the number 1 priority, PV1 is second, PV2 is
third, and PV3 is fourth. However, you can set PV1 to have the top
priority and PV4 to be second by entering a “/” as the eighth character in
the Tag ID.

Note that the transmission rate for the various PVs depends on the number
of PVs that are selected for broadcast. When more than one PV is selected,
the “priority” PV is sent every other broadcast cycle.

Set the LRV (which is the process input for 4 mA dc* (0%) output) and
URV (which is the process input for 20 mA dc* (100%) output) for the
differential pressure input PV1 by typing in the desired values on the SCT
configuration .

• LRV = Type in the desired value (default = 0.0)

• URV = Type in the desired value

(default = 100 inH2O@39.2 °F for SMV models SMA125
and SMG170)
(default = 10 inH2O@39.2 °F for SMV models SMA110)

* When transmitter is in analog mode.

ATTENTION • SMV 3000 Transmitters are calibrated with inches of water ranges

using inches of water pressure referenced to a temperature of 39.2 °F
(4 °C).

• For a reverse range, enter the upper range value as the LRV and the

lower range value as the URV. For example, to make a 0 to 50 inH2O
range a reverse range, enter 50 as the LRV and 0 as the URV.

• The URV changes automatically to compensate for any changes in the

LRV and maintain the present span (URV – LRV).

• If you must change both the LRV and URV, always change the LRV

first.

• SQUARE ROOT

d

Factory setting.

The PV1 output is normally set for a straight linear calculation since
square root is performed for PV4. However, you can select the
transmitter’s PV1 output to represent a square root calculation for flow
measurement. Thus, we refer to the linear or the square root selection as
the output conformity or the output form for PV1.

For SMV 3000 transmitters measuring the pressure drop across a primary
element, the flow rate is directly proportional to the square root of the
differential pressure (PV1) input. The PV1output value is automatically
converted to equal percent of root DP when PV1 output conformity is
configured as square root.

You can use these formulas to manually calculate the percent of flow for
comparison purposes.

• 100 = %P

Where, ∆P = Differential pressure input in engineering units

Span = Transmitter’s measurement span (URV – LRV)
%P = Pressure input in percent of span

Range Values
(LRV and URV)

Internally, the SMV transmitter uses absolute pressure values for all flow
calculations. The value entered in the Atmospheric Offset field is added
to the gauge pressure input value to approximate the absolute pressure.
An inaccurate atmospheric pressure offset value will result in a small error
of the flow calculation.
Use an absolute pressure gauge to measure the correct atmospheric
pressure. A standard barometer may not give an accurate absolute
pressure reading.

The Lower Range Value and the Upper Range Value fields for PV2 are
found on the AP/GPConf tab card.

Set the LRV (which is the process input for 0% output and URV (which is
the process input for 100% output for the static pressure input PV2 by
typing in the desired values on the SCT tab card.

• URV = Type in the desired value

(default = 50 psia for model SMA110)

(default = 3000 psig for model SMG170)

NOTE: Static pressure may be absolute or gauge pressure, depending on the model

SMV 3000 you have selected.

ATTENTION • The range for PV2 is static pressure (as measured at the high pressure

port of the meter body).

• The URV changes automatically to compensate for any changes in the

Cold Junction
Compensation

Background

If a thermocouple is used for process temperature PV3 input, you must
select if the cold junction (CJ) compensation will be supplied internally by
the transmitter or externally from a user-supplied isothermal block.

Specify source of cold junction temperature compensation.

• Internal

• External - Must also key in value of cold junction

temperature for reference.

Every thermocouple requires a hot junction and a cold junction for
operation. The hot junction is located at the point of process measurement
and the cold junction is located in the transmitter (internal) or at an
external location selected by the user. The transmitter bases its range
measurement on the difference of the two junctions. The internal or
external temperature sensitive resistor compensates for changes in ambient
temperature that would otherwise have the same effect as a change in
process temperature.

If you configure CJ source as external, you must tell the transmitter what
cold junction temperature to reference by typing in the temperature as a
configuration value. For internal cold junction configuration, the
transmitter measures the cold junction temperature internally.

Output Linearization

Background

For process temperature (PV3) input, configure output to represent one of
these characterization selections.

• Lineard - Output is in percent of temperature span.

• Unlinearized - Output is in percent of resistance span for

RTD or millivolts or volts span for T/C.

d

Factory setting.

You can have the transmitter provide a linear output which is linearized to
temperature for PV3 input, or a nonlinear output which is proportional to
resistance for an RTD input, or millivolt or volt input for T/C input. Also,
if you do switch from linear to unlinearized or vice versa, be sure you
verify the LRV and URV settings after you enter the configuration data.

d

Factory setting.

You can turn the transmitter’s temperature sensor fault detection function
ON or OFF through configuration.

• With the detection ON, the transmitter drives the PV3 output to

failsafe in the event of an open RTD or T/C lead condition. The
direction of the failsafe indication (upscale or downscale) is
determined by the failsafe jumper on the PWA, (See Subsection 8.3).

• When fault detection is set to OFF, these same failsafe conditions

result in the transmitter for an open RTD sensing lead or any T/C lead.
But when an open RTD compensation lead is detected, the transmitter
automatically reconfigures itself to operate without the compensation
lead. This means that a 4-wire RTD would be reconfigured as 3-wire
RTD, if possible and thus avoiding a critical status condition in the
transmitter when the transmitter is still capable of delivering a
reasonably accurate temperature output.

The Lower Range Limit (LRL) and Upper Range Limit (URL) identify the
minimum and maximum flow rates for the given PV4 calculation. The
LRL is fixed at zero to represent a no flow condition. The URL, like the

ATTENTION

Low Flow Cutoff for
PV4

Adjust the damping time constant for flow measurement (PV4) to reduce
the output noise. We suggest that you set the damping to the smallest
value that is reasonable for the process.

The damping values (in seconds) for PV4 are:

10.0, 50.0 and100.0

d

Factory setting.

The electrical noise effect on the output signal is partially related to the
turndown ratio of the transmitter. As the turndown ratio increases, the
peak-to-peak noise on the output signal increases. See the Damping
paragraphs in subsection 6.6 for a formula to find the turndown ratio using
the pressure range information for your transmitter.

For calculated flow rate (PV4), set low and high cutoff limits between 0
and 30% of Upper Range Limit for PV4 in engineering units.

• Low Flow Cutoff: Low (0.0 = default)

High (0.0 = default)

Background

ATTENTION

You can set low and high low flow cutoff limits for the transmitter output
based on the calculated variable PV4. The transmitter will clamp the
current output at zero percent flow when the flow rate reaches the
configured low limit and will keep the output at zero percent until the flow
rate rises to the configured high limit. This helps avoid errors caused by
flow pulsations in range values close to zero. Note that you configure limit
values in selected engineering units between 0 to 30% of the upper range
limit for PV4.

Figure 25 gives a graphic representation of the low flow cutoff action for
sample low and high limits in engineering units of liters per minute.

If the flow LRV is not zero, the low flow cutoff output value will be
calculated on the LRV and will not be 0 %.

6.10 Using Custom Engineering Units

Using Custom Units
for PV4 Flow
Measurement

The SCT contains a selection of preprogrammed engineering units that you
can choose to represent your PV4 flow measurement. If you want the PV4
measurement to represent an engineering unit that is not one of the
preprogrammed units stored in the SCT, you must select custom units and
enter a tag that identifies the desired custom unit.

Using the SCT, selecting Custom Units allows you to choose a unit that is
compatible with your application process. Additionally, a conversion factor
must be calculated and entered when configuring the PV4 flow variable.
This conversion factor is a value used to convert the standard units used by
the SMV into the desired custom units. The standard units used by the SMV
are:

• Tonnes/hour – for mass flow

• Meters

3

/hour – for volumetric flow

6.11 Flow Compensation Wizard

Description

Standard Equation

A Flow Compensation Wizard is provided with the SCT 3000 which is
used to configure PV4, the flow variable of the SMV 3000 Multivariable
Transmitter. The flow compensation wizard will guide you in configuring
the PV4 output for either a standard flow equation or a dynamic
compensation flow equation.

• You can access the flow compensation wizard by pressing the

Wizard . . .

button in the SCT /SMV 3000 configuration

window.

• Refer to the SCT 3000 on-line User Manual for detailed

information for using the flow compensation wizard.

The SMV 3000 standard flow equation is a simplified version of the
ASME MFC-3M flow equation. The SMV 3000 uses the standard
equation to compensate for the density changes in gases, liquids and steam
(saturated and superheated) and can be used with any primary flow
element that behaves according to the following equation:

Flow =

Dynamic
Compensation
Equation

See Appendix C for the SMV 3000 standard flow equations and examples
of flow configuration using the flow compensation wizard.

The SMV 3000 dynamic compensation flow equation is the ASME flow
equation as described in ASME MFC-3M, “Measurement of Fluid Flow in
Pipes Using Orifice, Nozzle and Venturi.” The dynamic compensation
flow equation should be used to increase the flow measurement accuracy
and flow turndown for the primary elements listed in Table 18.

7.2 Startup Tasks

About Startup

Step Procedures

BAD PV displayed on
TPS/TDC systems

Once you have installed and configured a transmitter, you are ready to
start up the process loop. Startup usually includes

• Simulate pressure and temperature inputs to the transmitter,

• Reading inputs and outputs

• Checking zero input

You can also run an optional output check to “wring out” an analog loop
and check out individual PV outputs (in DE mode) prior to startup.

The actual steps in the startup procedure will vary based on the transmitter
type, the piping arrangement and the measurement application. In general,
we use the SCT to check the transmitter’s input and output under static
process conditions, simulate input signals and make adjustments as
required before putting the transmitter into full operation with the running
process.

For SMV transmitters that are digitally integrated with Honeywell’s
TPS/TDC systems, note that simulated PV readings on Universal Station
displays will be flagged as BAD PV although the “PVRAW” reading will
continue to be displayed will reflect the simulated input.

7.3 Running Output Check

Background

ATTENTION

Analog Output Mode
Procedure

An SMV transmitter operating in the analog mode can be put into a
constant-current source mode (called the output mode) to checkout other
instruments in the control loop such as recorders, controllers, and
positioners. Using the SCT, you can tell the transmitter to change its
output to any value between 0 percent (4mA or 1V) and 100 percent
(20mA or 5V) and maintain that output. This makes it easy to verify loop
operation through the accurate simulation of transmitter output signals
before bringing the loop on-line.

For SMV transmitters operating the DE mode, you can simulate an output
for each PV individually to verify output at the digital receiver or DCS.
Follow the steps in Table 20 for transmitters in DE mode.

The transmitter does not measure the given PV input or update the PV
output while it is in the output mode.

IMPORTANT: Before performing this procedure, you must check the

calibration of the transmitter’s D/A converter. Perform
the procedure “The Steps to Calibrate for PV4 Output,”
found in the Calibration section of the SCT on-line user
manual.

The procedure in Table 19 outlines the steps for checking the PV output
for SMV transmitter operating in analog mode.

Table 19 Analog Output Check Procedure

Step Action

Connect SCT to SMV and establish communications. (See

7.4 Using Transmitter to Simulate PV Input

Using SMV
Transmitter in Input
Mode

CAUTION

ATTENTION

You can use an SMV 3000 transmitter to simulate a PV input value
through the transmitter’s input mode. This feature is useful to check a
PV’s affect on the transmitter’s output and compare expected readings on
other analog instruments in the loop such as recorders, controllers, and
positioners. For SMV transmitters operating in DE mode, inputs can be
simulated for each PV to check the transmitter’s outputs on Universal
Station displays with our TPS/TDC systems.

Using the SCT, you can tell the transmitter to change a PV input to any
acceptable range value and maintain that input. This makes it easy to
check PV input operation through the accurate simulation of input signals.
This is especially helpful in verifying the affect of a given input on the
PV4 calculated flow rate output.

NOTE: The input mode overrides the output mode.

When the transmitter is in the input mode:

• The simulated PV input value is substituted for the measured input

• The output reflects the simulated input.

For SMV transmitters that are digitally integrated with Honeywell’s
TPS/TDC systems, note that PV readings on Universal Station displays
will be flagged as BAD PV although the “PVRAW” reading will continue
to be displayed will reflect the simulated input.

Input Mode Procedure

The procedure in Table 21 outlines the steps for using the transmitter in its
input mode and clearing the input mode.

you must measure the absolute static pressure and then enter that
value in the Atmospheric Offset field of the GPConf tab card.

Internally, the SMV transmitter uses absolute pressure values for all
flow calculations. The value entered in the Atmospheric Offset field is
added to the gauge pressure input value to approximate the absolute
pressure. An inaccurate atmospheric pressure offset value will result
in a small error of the flow calculation.

Use an absolute pressure gauge to measure the correct atmospheric
pressure. A standard barometer may not give an accurate absolute
pressure reading
