Introduction
Equipment Description
The Caldon* LEFM 3xxCi1ultrasonic flowmeter is a highly sophisticated bidirectionalflow measurement
system that employs ultrasonic transit time to measure fluid velocity and volumetric flow rate.Its advanced
signal and data processing circuitry help ensure high accuracy and repeatability. The LEFM 3xxCi can be
configured to indicate direction of flow via either a quadraturepulse outputor a digital signal.It can also be
configured to output positive flow pulses on one channeland negative flow pulses on the other.
The LEFM 3xxCi also contains an automatic fault detection system for verifying performance and alerting
personnel whenabnormal operating conditions are detected. For ease of troubleshooting, the LEFM 3xxCi
provides easy-to-interpret diagnostic information via Modbus communications and the local display.
This manual provides detailed instructions on the installationand operation of the flowmeter to include the
viewing of flow parameters and interpretation of diagnostic data viewed via the transmitter’s display. Users
who require a moredetailedview of diagnostic acousticdata can accessthe data via Cameron’s LEFMLink
software. The operation of this software is outside the scope of this manual. See the LEFMLink User
Manual for details.
The LEFM 3xxCi flowmeter has two basic components or subsystems:
•A meter body, including up to eight pairsof transducers forming acoustic pathsand a temperature
sensor
•A transmitter(s)containing a readoutdisplayand acoustic data processingelectronics
The meter body now has updated features that have been introduced in2013. These features complywith
the requirements of Measurement Canada (PS-G-06), OIML R-137, and ISO 17089-1:2010. They include:
•Removable manifold covers for easy access to the transducer components
•Ability to seal the transmitterand meter bodyto all changes affecting metrological performance
•Positive indication of the degradation inany primary seal with a secondary seal design that
complies with the requirements of ISA 12.27.01
The meterdesign typically mounts the transmitter to the meterbody at the factory and theassembly is
shipped asone instrument,ready for installation. Remote-mountunits are available,particularly when there
are extreme temperatures at the meter itself. This manual covers two different configurations. These are
described as follows:
1The term 3xxCi encompasses all versions of the gas ultrasonic flowmeters. Specifically, the 340Ci (4-path), and the 380Ci (8-
path) models are covered. Further, different meter body configurations are covered.

LEFM 3xxCi Meter Body
The meterbody containsup to eight pairs of acoustic transducers and a temperature sensor (RTD).
The meter body is a specially designed section ofpipe that contains pairs of transducer housings that are
positioned to provide acoustic paths ata 65° angleto the flowdirection. They are spaced in accordance
with theGaussian Method offlow integration. The transducers are installed inside these housings.
Each transducer module contains a piezoelectric crystal which transmits and receives acoustic energy in
the form of ultrasonic pulses (typically200 kHz). A distinguishing design feature is that the transducer
modules may be removed from their housings for maintenance while the meter body is in the pipeline
without affecting the pressure boundary (i.e. no special extraction tools required).
LEFM 3xxCi Transmitter
The transmitter houses the display, which shows the flow data, including flow rate, total flow volume, gas
properties, analog input data, alarm indication, fault detection, and acousticdiagnostic information.
The transmitter performs all control and timing for the generation and measurement of acoustic pulses.
Acoustic processing is performed byspecializedproprietary boardsthat are designed to achieve high
sampling rates, provide stable ultrasonic signals, and eliminate zero drift. The circuit boards withinthe
transmitter areprogrammed to perform the following functions:
•Step through the ultrasonic path cycles
•Providegain controlfor each ultrasonic path
•Compute flow
•Generate pulse outputs and analog outputs
The transmitteroffers the following inputs/outputs:
•Standard volume pulse output
•The K-factors used to configure transmitters at the factory are listed in Table 1.1. The user may

Direct-Mount Meter and Transmitter Installation (Model 3xxCi)
The LEFM 3xxCi flowmeters are designed for usewith a broad range ofprocess and environmental
conditions. Durable construction permits conventional installation practices. The flowmeter body is typically
fabricated of stainless steel, carbon steel, or duplexsteel, depending oncustomer requirements. The
flowmeter is designed to be as strong asor stronger than pipe and flanges ofthe same schedule, pressure
class, and material. For site stress analysis, the metercan be conservatively treated as equivalentpipe.
Installation procedures vary, depending on whether the transmitter is attached directly to the meter body, or
mounted remotely from the meter body. This sectiondescribes thedirect-mount installation in which the
transmitter is mounted directly to the meter body (Model 380Ci). Section 1 addresses the remote-mount
installation method in which the transmitter is mounted separately from the flowmeter, typically due to
extreme environmental reasons (forexample,high or lowpipe temperatures). Remote mounting of the
electronics is for Model 380Ci-R.
Flowmeter Body Installation – Best Practices
The weights of the flowmeter body are listed in Table 1.3 and Table 1.4. Never use the transmitter,
conduit or junction boxes for lifting or maneuveringthe meter body. These components are not
designed for theforces required to move the meter body and could be damaged.
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 forthe
LEFM meter body. However, the piping immediately upstream and downstream of the flowmeter should be
well supported in accordance with good piping practices andsite seismic requirements. See Section 1 for
LEFM weight and size information.

Lifting/Hoisting the Meter Body
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.
Hoist Ring Installation
1. Before installing hoistrings, refer to your company’shoisting 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 foundin OSHA 29 CFR1926.251(Rigging
Equipment for Material Handling) and 1926.552 (Material Hoists, Personnel Hoists, and Elevators).
2. Identify the assembled weight ofthe meterbody from the serial tag or by referencing Table1.4.
3. Place the meter on a stable surface or platform capable ofsupporting its assembledweight.
Failure to properly stabilize and support the meter body during installationor 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.
Figure 2.1 Stainless steel bolt and washer in tapped hole of meter body end flange
5. Use only Cameron swivel hoist rings (ordered separately; see Table 2.1) in the meter body end
flanges. DO NOT USE the following:
a. Eyebolts
b. Other hoist rings with the same screw size
c. Heavy-duty hoist rings

6. Screw the swivel hoist rings into the tapped holes. To ensure thehoist ringshold theirrated load,
the baseof the hoistring must be in full contact withthe surface ofthe tapped holes before
attempting to lift/hoist the meter body.
7. Torque the swivel hoist ring attachments to the site recommended limit for that bolt size. DO NOT
over-torque.
8. Verify that the ringsmove freely in all directions.

Sling Attachment
Ensure that the meter body is detached from all piping, pipe fittings, and/or metertubes before
lifting/hoisting the meter. Failure to take this precaution may result in damageto equipment and/or
personal injury, up to and including death.
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.
NEVER attempt to thread one sling throughboth 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 slingsof equal length that exceedthe 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 slingsto the hoist rings, ensuring that the angle between the slingsis 90 degrees or less
(see Figure 2.2). DO NOTwrap slingsaround the meter bodyor the transmitterenclosure.

To avoid damaging the swivel hoist rings, never use cables, hooks, or chains to lift the meter body.
Lift the metergradually. 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.
5. After lifting, remove the swivelhoist rings and store away from exposure to
moisture, extreme temperatures, and other adverse conditions.
6. Reinsert the plug bolts into the tapped holesto protect them from debris and corrosion.
Meter Installation
Install the flowmeter so that:
•The acoustic paths are horizontal (with the transmitter and nameplate on top) to decrease the
likelihood of debris accumulating in the sensor wells.
•The flow arrow indicates the flow direction for positive flow.
•All wiring to the transmitter is routed in shielded conduit/ armored cablethat meetssite
environment specifications.
•All power connections on site shallgo through anequipment switch orcircuit breaker employed as
a disconnectingdevice. This switch shall be easily accessed and be marked as the disconnecting
switch for the transmitter. This switch shallmeet the requirements of IEC 60947-1 and IEC 60947-
3 and site electrical codes.
•If using DC power, powercable must beinstalled in separate conduit fromall othercabling. This is
to meet requirements of IEC 61000-4-4 (2004-07).
•380Ci Installations: Upstream of the meterthere should be at least 5 diametersof straight pipe of

at least 3diameters of straight pipe of the same nominaldiameter as the meter.
•Process temperature and pressure should be measured within 2 to5 diameters downstream of the
meter. The pressure measurement maybe made at the downstream spool ahead of the
temperature measurementor optionally at the meter body itself.
CAUTION
