CALDON LEFM 280CiRN Ultrasonic flowmeters APPLICATIONS ■■ Custody transfer ■■ Check or allocation metering ■■ Leak detection/line balance ■■ Heavy oil installations BENEFITS ■■ Reliable and long-term stability ■■ Smaller prover size FEATURES ■■ ■■ ■■ ■■ ■■ ■■ ■■ Insensitivity to swirl Electronics can be integrally or remote mounted Available in 6- to 40-in sizes ± 0.10% linearity over the nominal flow range No limit on operating Reynolds number OIML R 117-1 Edition 2007 (E); Accuracy Class 0.3 Measuring oils with high viscosity and/or in low flow conditions may involve operating at Reynolds numbers below 10,000. Ultrasonic flowmeter performance has traditionally been degraded for Reynolds numbers below 10,000 because the liquid velocity profile erratically switches between laminar and turbulent characteristics. Cameron has developed a new ultrasonic flowmeter design with a reduced bore and a special nozzle shaped entry in which the liquid velocity profile is stabilized by forces much larger than the forces imposed by fluid viscosity. The meter design stabilizes the flow profile while preventing boundary layer separation under all operating conditions, greatly improving performance. The CALDON* LEFM 280CiRN Series eight-path reduced nozzle liquid ultrasonic flowmeter provides the highest possible performance and has an excellent success rate of achieving a data spread of 0.05% in five prover runs. Meter construction The CALDON LEFM 280CiRN meter body is designed and manufactured in accordance with ASME B31.3 Process Piping Code or the Pressure Equipment Directive (PED) 97/23/EC and is suitable for handling pressurized liquid hydrocarbons. It has 16 piezoelectric transducer modules (typically 1.0 MHz or 1.6 MHz) forming four chordal paths. These are mounted in pressure containing housings and can be replaced while the meter body is under operating pressure. Ingress protection rating for transmitter and meter body is IP66 (NEMA 4/4x).

Meter factor is unaffected by usage. 15:1 based on nominal maximum flow rate above. OIML R 117-1 Edition 2007 (E); Accuracy Class 0.3. Approximately 5 psi at maximum flow (diffuser recovers 70% of the velocity head differential). The meter can operate on water in oil content as high as 50% provided the water in oil are well mixed, typically at velocities above 6.5 ft/s [2.5 m/s]. Meter operation may be affected if the water and oil phases separate or are not well mixed. Contact Cameron for further advise on high water-cut applications. Maximum allowable viscosity is based on the meter size and the maximum allowable signal strength/attenuation. Consult Cameron for fluid viscosity greater than 1,000 cSt. Installation In order to limit uncertainty caused by hydraulic effects, it is recommended that the installation of the LEFM 280CiRN flowmeter comply with the following guidelines. The adjoining straight pipe should be of the same schedule as the meter. Temperature elements and pressure connections should be located downstream of the meter. The LEFM 280CiRN flowmeter does not normally require the use of a flow conditioning element. An uninterrupted upstream pipe five pipe 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 10 pipe diameters in length. Downstream of the meter there should be an uninterrupted pipe at least three pipe diameters in length. For application specific recommendations or more detailed installation guidance, please consult Cameron. Pressu re Tempe rature ~5D Meter 3D Min .

This greatly improves short term repeatability of the reduced bore design compared to a full bore design for transition flow.

The reduced bore design maintains performance from turbulent flow, through the transition range, and down into laminar flow. This data was taken over a 25:1 range in flow rate which equated to a 1000:1 range in Reynolds number. CALDON LEFM 280CiRN LEFM SystemLink G3 The LEFM SystemLink G3 user interface software technology allows access to real-time diagnostic data, historical data, and event logs from a G3 ultrasonic flowmeter by using an Ethernet/ fiber optic modem connection. Historical data and event logs are stored within the G3 transmitter, thus allowing for later retrieval— giving operators ability to monitor and analyze critical diagnostics, helping prevent unplanned downtime. LEFM SystemLink G3 features: Health overview report show the current meter status as well as meter process measurements including flow rate, temperature, and pressure ■■ ■■ ■■ Detailed charts and graphs present the meter diagnostic information in an easy-to-understand format with alarm limits that help identify issues User defined reference points are built using the meter's stored data. These reference points allow the user to graphically compare current meter performance against user defined reference points. For example, current performance can be compared against calibration or commissioning data. Calibration lab The Cameron Hydrocarbon Calibration Laboratory is a state-of-the-art facility located in Pittsburgh, PA. Every Caldon LEFM 200 series ultrasonic flowmeter is calibrated in this laboratory using up to three oils. The ability to use multiple oils allows calibration over a Reynolds number range that includes that of the customer's application. This ensures meter performance will be unaffected by changes in flow rate and viscosity once the meter is installed.
