Caldons background is centeredin ultrasonic technology andhas often pioneered its use tosolve difficult and demandingmeasurement problems in thenuclear, hydroelectric anddefense industries. Caldonhas established the strongestbase of ultrasonic transit timeknowledge in the world that has

been field proven for more than30 years.

Now, Caldon has focusedthis knowledge on petroleummeasurement and is pleasedto announce the LEFM200Ultrasonic Flow Meter. TheLEFM 200 is a compact, highperformance instrument,specifically designed to handleliquid petroleum applications

such as custody transfer, leakdetection, line balance, checkmetering, allocation, andprocess control.

LEFM200 meters recentlydemonstrated their performancein field tests with a major U.S.pipeline company. Theiraccuracy surpassed industrystandards for both positivedisplacement and turbine metertechnologies. The LEFM 200won praise for simplicity ofdesign, ease of installation,

low pressure losses, fieldprovability, and extremeaccuracy. Caldon demonstratedprecision where it really countsin the field. The LEFM 200repeatability was measured at0.013% in accordance with APIproving standards when provedwith a stationary pipe prover.Batch comparison with thecompanys flow meters waswithin 6 barrels in 61,000barrels1 part in 10,000!

Two paired transducers forman acoustic path so that oneis upstream of the other.They send and receive pulsesof ultrasonic sound, both inthe direction of flow and againstthe flow. These pulses take lesstime to cross the pipe travelingin the direction of the flow thanwhen against the flow. Thisdifference between upstreamand downstream path times,called the transit time, providesa means to calculate the fluidvelocity.

Each spool piece containseight (8) transducers, whichform four (4) parallel, chordalpaths. The transit times of theacoustic pulses are measuredalong each path, and used todetermine the fluid velocity atthat path. The fluid velocitiesfor the paths are numericallyintegrated to calculate the flowprofile within the pipe. Theresult is a true volumetric flowrate unaffected by changes inflow profile. In other words, theaccuracy of the LEFM200 isfundamentally independent offlow rate and viscosity.

The savings called out in the graph and thechart are based on a typical 17 psi pressuredrop reduction created by the LEFM 200.

There is virtually no pressure dropcreated by the LEFM 200 becauseit is a full bore device. In addition,the LEFM 200 does not requirethe installation of a strainer toprotect internal components, as domechanical meters. The LEFM 200creates less pressure loss whencompared to positive displacementor turbine meters, generally equalto a minimum of 17 psi (120 kPa).Lower pressure loss translatesinto reduced electrical powerrequirements for pumps, and anincrease in flow rate through thesystem. The savings generated by

this lower pressure loss normallyallows the LEFM 200 to pay foritself within a few months.

Use the following equation forsavings in $/hr for differentpressure drop values:

LEFM Savings ($/hr) = P (psi) x Q (BPH) x E ($/kW2448
