MEASUREMENT SYSTEMS

• Leading Edge Flow Meter (LEFM) technology developed by Westinghouse inthe 1960’s

• First chordal multipath meter patent issued to Westinghouse in 1971

• LEFM technology acquired by Caldon in 1989

• New custody transfer product line introduced in 1999

• Caldon acquired by Cameron in 2006

• Caldon ISO 17025 approved Liquid Calibration Laboratory. Flexibility inscheduling customer calibrations, thus control over complete deliveryschedule

• Gas Meter employs same proven chord configuration as liquid family

MEASUREMENT SYSTEMS

LEFM 380Ci Custody Transfer GUSM• Uncertainty:

±0.1% relative to calibration facility

• Operational Benefits– Unique Non-Wetted isolated transducers (Titanium pressure boundary),

designed with health and safety in mind

– Transducers capsules can be inspected or replaced under line conditions; no high pressure extractor tools required.Designed for optimum safety whilst avoiding unnecessary depressurization and emissions. Virtually eliminatestransducer failures.

– Transducers not susceptible to explosive de-compression during plant emergency shut down

– Full Bore meter

RAISING PERFORMANCE. TOGETHERTM

– Full Bore meter

– On application upstream lengths can be shortened to 5D

– LCD Display with resettable and non-resettable Totals

– Tolerant to corrosive compounds such as H2S

– No exposed transducer cabling for optimum protection

– Special Coating prevents deposits from forming increasing calibration intervals (Resists corrosion, preventscontamination)

• Installation Benefits– 8-Path Dual plane design for swirl immunity

– Proven Gaussian Chordal Integration employed in LEFM since early development by Westinghouse in the1960’s

– Can be used without deploying a flow conditioner thus saving on compression/ energy costs

– Eliminates maintenance associated with flow conditioner fouling

LEFM 240CiRN or 280CiRN Reduced Bore Meter

• Global Installed Base

• 240CiRN (4 Path) or 280CiRN (8 path)

• Can be calibrated with direct proving againstcompact and ball provers, using volumes/runsmore than 6 times smaller than conventionalUSM technology.

• Designed for high viscosity applications

– Typical Re < 10,000

RAISING PERFORMANCE. TOGETHERTM

– Typical Re < 10,000

– Solves the hydraulic problems in transitionsuch that we can achieve performancewithin +/- 0.15% or +/- 0.12 % through thetransition region

• Approximately still 50% pressure loss of aTurbine meter/ bundle without consideringturbine strainer requirements

• On application certified custody transferaccuracy can be now be achieved with Caldonmeters for oils of up to 3,000 cSt viscosity!

MEASUREMENT SYSTEMS

LEFM 280CiLT-R LNG METER

• 8-path Flowmeter designed exclusively for LiquefiedNatural Gas

• Proven LNG application references

• Designed for swirl immunity

• Transducer design optimised for LNG measurement

• Proper calibration is of vital importance as the meterswill be used without an in-situ prover. Caldon’scalibration methodology for LNG is based on velocity

RAISING PERFORMANCE. TOGETHERTM

calibration methodology for LNG is based on velocityprofile, not Reynolds number facilitated by unique keycharacteristics of meter design

• NMi, the Dutch weights and measures authority, havereviewed Caldon’s methodology and test data

• Full consideration of the flow and thermal effects

• The report states a maximum uncertainty of +/- 0.18%
