Caldon 388Ci 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

  • 4- and 8-path chordal designs for optimal linearity and repeatability
  • Industry-leading 8-path chordal design with dramatically reduced sensitivity to swirl and asymmetry effects
  • Two fully independent 8-path configurations for 100% redundancy or check metering at reduced cost
  • 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

  • Advanced signal processing with real-time diagnostic analysis
  • Internal resistance temperature detector (RTD) for thermal expansion compensation
  • Caldon USM Advisor™ diagnostic software included
  • G3 electronics with rich I/O and an integral SD card
  • Compliance with American Gas Association (AGA) Report No. 9, International Organization of Legal Metrology (OIML) Recommendation R 137 Accuracy Class 0.5, and ISO 17089-1

How it improves performance

The Caldon™ 388Ci LEFM ultrasonic gas flowmeter features two independent 8-path flowmeters in one compact body, providing full redundancy at a reduced cost.
