Caldon 380Ci LEFM ultrasonic gas flowmeter
Reliable custody transfer measurements for gaseous hydrocarbons
Applications
- Custody transfer
- Transmission measurement
- Import and export metering
- Check metering
- Gas storage
Benefits
- Industry-leading 8-path chordal design for optimal linearity and repeatability, 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
- Compact footprint
- 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
- Eight-path, dual-plane configuration
- Advanced signal processing with real-time diagnostic analysis
- Internal resistance temperature detector (RTD) for thermal expansion compensation
- Caldon USM Advisor™ diagnostic software included
- Configurable design that enables accepting various end-connection requirements
- Compliance with American Gas Association (AGA) Report No. 9, International Organization of Legal Metrology (OIML) Recommendation R 137, and ISO 17089-1
How it improves performance
The Caldon™ 380Ci LEFM ultrasonic gas flowmeter features an advanced 8-path design that reduces sensitivity to swirl and nonaxial flow, improving performance with or without a flow conditioner. The ability to remove the flow conditioner enables custody transfer performance without the potential impacts of conditioner blockage, acoustic noise, and pressure loss associated with most flow conditioning elements.
