Section 1: Introduction
1.1 EQUIPMENT DESCRIPTION
The CALDON*SVMError! Bookmark not defined.Error! Bookmark not defined. 289Ci*ultrasonic
flowmeter is a highly sophisticated bidirectional flow measurement system that employs ultrasonic transit
time to measure volumetric flow rate and evaluate the uncertainty in the measurement result. Its
advanced signal and data processing are designed to provide robust, high accuracy measurement and
unique self-verification capabilities.
CALDON SVM technology employs the proven Caldon 8-path configuration for its primary measurements.
The 8-path configuration uses pairs of crossed paths in each of four chordal planes to effectively cancel
non-axial velocities and accurately integrate the axial velocity profile. The 8-path primary measurement is
the foundation of our SVM 289Ci which has 16 paths in total and incorporates three significant features to
produce an ultrasonic meter with unique and unrivalled self-verification ability:
•Primary (axial velocity) measurement verification per chord
•Fifth chordal measurement plane to facilitate 4-chord vs 5-chord estimation of flow profile uncertainty
•Vertical reflective path for detection of entrained gas or contamination.
SVM technology enables the simultaneous calculation of measurement uncertainty alongside each flow
measurement calculation. In addition to the continuous and instantaneous output of uncertainty in terms
of volumetric flowrate or relative percentage value, the SVM totalizes uncertainty values internally. The
SVM 289Ci flowmeter contains an automatic fault detection system for verifying performance and alerting
personnel when abnormal operating conditions are detected. For ease of troubleshooting, the SVM 289Ci
flowmeter provides easy-to-interpret uncertainty and diagnostic information via Modbus communications
and the local display.
This manual provides detailed instructions on the installation and operation of the flowmeter including the
viewing of flow parameters and interpretation of diagnostic data viewed via the transmitter’s display.
Users who require a more detailed view of uncertainty, or diagnostic and signal data can access the data
via the CALDON USM Advisor software. The operation of this software is outside the scope of this
manual. See the USM Advisor User Manual for details.
The SVM 289Ci flowmeter has two key components: a meter body and a transmitter.
Typically, the transmitter is mounted to the meter body, tested at the factory, and shipped as a fully
assembled instrument, ready for installation.
1.1.1 SVM 289Ci METER BODY
The meter body contains 16 pairs of ultrasonic transducers and a temperature sensor (RTD). Refer to
Figure 1.1, page 9 for a depiction of the meter body and transmitter assembly.
The meter body is a specially designed flow conduit that contains multiple pairs of transducer housings
that are positioned to form ultrasonic paths at an angle to the flow direction. The transducers are installed
inside these housings and are isolated from the fluid and external to the pressure containment. The four
primary chordal planes are spaced in accordance with the Gaussian Method of flow integration.
Each transducer module contains a piezoelectric element that transmits and receives acoustic energy in
the form of ultrasonic pulses.
∗Mark of Sensia
* The SVM 289Ci is the latest addition to the Leading Edge Flow Meter (LEFM) family. It is designated SVM for Self-Verifying Meter.
However, LEFM and SVM can be used interchangeably, e.g., the LEFM/SVM 289Ci is part of the LEFM 2xxCi family of meters.

1.1.2 G3 TRANSMITTER
The transmitter houses the display that provides readouts of flow data including flow rate, total flow
volume, fluid properties, analog input data, alarm indication, fault detection, and diagnostic information.
The transmitter performs all control and timing for the generation and measurement of ultrasonic pulses.
Signal and data processing is performed by specialized proprietary circuit boards that are designed to
achieve high sampling rates, provide stable ultrasonic signals, and eliminate zero drift. The circuit boards
within the transmitter are programmed to perform the following functions:
•Step through the ultrasonic path cycles
•Measure meter body temperature (for thermal expansion correction, see Section 4: Understanding
Flow Calculations)
•Compute flow
•Communicate with external devices
•Generate pulse outputs and analog outputs
The transmitter offers the following inputs/outputs:
•Three optional 4-20 mA analog inputs can be mapped to any of the following:
−Product temperature
−Product pressure
−Product density
−Product viscosity
•Two optional 4-20 mA analog outputs
−Flow
−Product temperature
−Product pressure
•Communications
−Up to three RS485 ports (half duplex) – Modbus RTU
−Ethernet port (via copper or fiber) with Modbus TCPIP
−Optional HART channel (operates on second analog output)

Section 2: Meter Body Installation
SVM 289Ci flowmeters are designed for use with a broad range of process and environmental conditions.
Durable construction permits conventional installation practices. The flowmeter body is typically fabricated
of stainless steel, carbon steel, or duplex steel, depending on customer requirements. The flowmeter is
designed to be as strong as or stronger than pipe and flanges of the same schedule, pressure class and
material. For site stress analysis, the meter can be conservatively treated as equivalent pipe.
CAUTION
The weights of the flowmeter body are listed on the customer-specific General Arrangement
Drawing. Never use the transmitter, conduit boxes or junction boxes for lifting or
maneuvering the meter body. These components are not designed for the forces required to
move the meter body and could be damaged.
CAUTION
If the equipment is likely to come into contact with aggressive substances, then it is the
responsibility of the user to take suitable precautions that prevent it from being adversely
affected, thus ensuring that the type of protection is not compromised.
No external supports or special mounting pads are required or recommended for the SVM meter body.
However, the piping immediately upstream and downstream of the flowmeter should be well supported in
accordance with good piping practices and site seismic requirements.
1.1 LIFTING/HOISTING THE METER BODY
WARNING
If the swivel hoist rings have been used previously, inspect them for signs of wear,
corrosion, or stress. If the rings appear damaged or corroded, DO NOT USE.
2.1.1 HOIST RING INSTALLATION
Use only Sensia swivel hoist rings (ordered separately; see Table 2.1) in the meter body end flanges.
DO NOT USE the following:
•Eyebolts
•Other hoist rings with the same screw size
•Heavy-duty hoist rings

1. Before installing hoist rings, refer to your company’s hoisting and rigging standards. If no such
company standards exist, refer to the Department of Energy (DOE) STD-1090-2011(Hoisting and
Rigging Standard). Additional information can be found in OSHA 29 CFR 1926.251 (Rigging
Equipment for Material Handling) and 1926.552 (Material Hoists, Personnel Hoists, and Elevators).
2. Identify the assembled weight of the meter body from the serial tag or by referencing the GA drawing.
3. Place the meter on a stable surface or platform capable of supporting its assembled weight.
WARNING
Failure to properly stabilize and support the meter body during installation or removal could
allow the meter to shift or roll, posing a hazard that may result in equipment damage or
serious injury, up to and including death.
4. Remove the plug bolts and sealing washers from the tapped holes on top of each meter body end
flange and set them aside. The plug bolts will be replaced after the hoist ring is no longer required, as
shown in Figure 2.1.

5. Screw the swivel hoist rings into the tapped holes. To ensure the hoist rings hold their rated load, the
base of the hoist ring must be in full contact with the surface of the tapped holes before attempting to
lift/hoist the meter body.
6. Torque the swivel hoist ring attachments to the site recommended limit for that bolt size. DO NOT
over-torque.
7. Verify that the rings move freely in all directions.
2.1.2 SLING ATTACHMENT
WARNING
Ensure that the meter body is detached from all piping, pipe fittings, and/or meter tubes
before lifting/hoisting the meter. Failure to take this precaution may result in damage to
equipment and/or personal injury, up to and including death.

WARNING
Failure to properly stabilize and support the meter body during installation or removal could
allow the meter to shift or roll, posing a hazard that may result in equipment damage or
serious injury, up to and including death.
WARNING
NEVER attempt to thread one sling through both hoist rings. DO NOT exceed an angle of
90 degrees between the slings. Choose slings that exceed the swivel hoist ring load rating.
Failure to follow these precautions may result in hoist ring failure, equipment damage, or
serious personal injury, up to and including death.
1. Select two slings of equal length that exceed the load rating for the weight of the assembled meter
body.
2. Visually inspect the slings for signs of wear, abrasion, or other damage. DO NOT USE if damage is
detected.
3. Attach the slings to the hoist rings (see Figure 2.2).
Figure 2.2—Proper sling attachment
Important Ensure that the angle between the slings is 90 degrees or less. DO NOT wrap slings around
the meter body or the transmitter enclosure.
To avoid damaging the transmitter, ensure that the slings do not come into contact with the
transmitter enclosure. Consider using a spreader bar (as shown in Figure 2.3, page 18) to
ensure that the angle relative to the vertical does not exceed 45 degrees.

Figure 2.3—Hoist rings with a lifting bar above the electronics unit allow for uniform lifting.
CAUTION
To avoid damaging the swivel hoist rings, never use cables, hooks, or chains to lift the meter
body. Lift the meter gradually. Exposing the swivel hoist rings to shock loads can result in
damage to the hoist ring. DO NOT USE any swivel hoist ring exposed to shock loads.
4. After lifting, remove the swivel hoist rings and store away from exposure to moisture, extreme
temperatures, and other adverse conditions.
5. Reinsert the plug bolts into the tapped holes to protect them from debris and corrosion.
2.2 METER INSTALLATION
Install the flowmeter so that:
•The primary measurement chords are horizontal (with the transmitter on top) to decrease the
likelihood of debris or air (gas) accumulating in the sensor wells.
•The meter is not located at a high point where air/gas could be trapped.
•The flow arrow should be pointing in the direction of “positive” flow.
•All wiring to the transmitter is routed in shielded conduit/armoured cable that meets site environment
specifications.
•All power connections from site shall go through a properly rated equipment switch or circuit breaker
employed as a disconnecting device (see Table 1.2, page 13, for ratings). This switch shall be easily
accessed and be marked as the disconnecting switch for the transmitter. This switch shall meet the
requirements of IEC 60947-1 and IEC 60947-3 and site electrical codes.
•If using DC power, power cable must be installed in separate conduit from all other cabling. This is to
meet the requirements of IEC 61000-4-4 (2004-07).
•To limit uncertainty caused by pipe fittings and fluid dynamic effects, install the SVM 289Ci model per
the following guidelines.
−The adjoining straight pipe should be of the same schedule as the meter.
−The SVM 289Ci does not normally require the use of a flow conditioning element. An
uninterrupted upstream pipe 5 diameters in length is adequate in most applications. In situations
where there is a constriction upstream of the meter that is smaller than the diameter of the meter
run piping (such as a reduced bore valve), it is recommended that this be separated from the
meter by a pipe at least 15 pipe diameters in length.

CALDON SVM 289Ci Section 2: Meter Body Installation
19
−Downstream of the meter there should be a straight length of at least 3 pipe diameters prior to
any bends, tees, reducers, expanders or valves etc.
−In uni-directional applications temperature elements and pressure connections should be located
downstream of the meter.
−Intrusive temperature elements should be at a distance of at least 2 pipe diameters from the
meter. Non-intrusive pressure connections may be located within 2 diameters of the meter.
Refer to Figure 2.4 for details. For application-specific recommendations or more detailed installation
guidance, contact Sensia.

Section 3: Transmitter Connections
CAUTION
The physical properties, configuration settings, and calibration of the meter body are pre-
programmed into the transmitter; therefore, the meter body and transmitter are manufactured
as a matched set and must be installed as a pair. Failure to install transmitters and meter
bodies as matched sets can result in erroneous flow measurements.
3.1 TRANSMITTER INSTALLATION PROCEDURE
Important All equipment should be installed by a licensed electrician in accordance with NEC/CEC or
local codes. At a minimum, install a disconnect switch in series with the transmitter power
input.
All wiring to and from the transmitter must be routed through grounded/shielded metal
conduit or equivalent that meets site environment specifications.
All power connections from site shall go through a properly rated equipment switch or circuit
breaker employed as a disconnecting device (see Table 1.2, page 13, for ratings). This
switch shall be easily accessed for disconnecting and be marked as the disconnecting
switch for the transmitter. This switch shall meet the requirements of IEC 60947-1 and IEC
60947-3 and site electrical codes.
For Class I, Div 1 installations, conductor insulation for external circuits must be rated for
300V and a minimum temperature of 85ºC.
3.1.1 TRANSMITTER LOCATION
To ensure that the proper supply voltage reaches the transmitter, the distance between the transmitter
and its power source must not exceed the maximum distance indicated below (based on the wire gage
used):
