Caldon 289Ci LEFM self-verifying liquid flowmeter

Applications

• Custody transfer
• Self-verification where proving is not possible
• Leak detection
• Refinery inlet and outlet
• Offloading
• Import and export metering

Benefits

• 16-path ultrasonic flowmeter with industry-first capability to provide live uncertainty output for enhanced self-verification
• Primary measurement based on industry-leading 8-path chordal design with dramatically reduced sensitivity to swirl and asymmetry effects
• 5-diameter minimum upstream pipe run and no requirement for flow conditioner, which reduces total cost of ownership
• Transducers that are isolated from the process and outside the pressure boundary for ease of service
• No recalibration or zeroing required if transducer is replaced
• In-house transducer manufacturing for maximum quality control
• Continuous logging capabilities
• Optional corrosion-, adhesion-, and contamination-resistant internal coating (proprietary)

Features

• Available sizes: 8 to 40 in (larger sizes available on request)
• Quantitative evaluation of meter performance, with a continuous and instantaneous output of uncertainty in velocity and flow rate
• Internal uncertainty totalizers that report uncertainty as a volumetric total
• Linearity ±0.1% over the nominal flow range
• Advanced signal processing with real-time diagnostic analysis
• Internal resistance temperature detector (RTD) for thermal expansion compensation
• Compliance with API MPMS Chapter 5.8, International Organization of Legal Metrology (OIML) Recommendation R 117-1 Edition 2019 (E) Accuracy Class 0.3, Measuring Instruments Directive (MID) 2014/32/EU, and NACE MR0175
• Independent technology qualification: DNV liquid fiscal metering Class L-AAA

How it improves performance

A breakthrough in the verification of ultrasonic liquid meters, the Caldon™ 289Ci LEFM self-verifying liquid flowmeter builds on the robustness and performance of our 8-path meter to deliver a quantitative evaluation of meter performance. Based on the current process and meter conditions, it outputs the flow rate and quantifies the uncertainty in this flow rate every second.
