ALTOSONIC V12

Ultrasonic gas flowmeter for custody transfer

ALTOSONIC V12 has been designed to offer the best possible measurement accuracy, not only during a calibration under ideal conditions but also during the less ideal conditions in the field. As a result ALTOSONIC V12 is the first ultrasonic flowmeter that was certified to OIML R137 class 0.5 by NMi.

Due to its design with 12 acoustic chords a flow conditioner is no longer required; standards such as AGA9, ISO 17089 and MID are met with just 5D straight inlet piping. CBM Flowmeter diagnostics are standard and give an exact picture of what is happening inside the flowmeter. With the optional KROHNE Care expert system an integrated web server becomes available that presents the results as an easy to access webpage in plain language.

Highlights

  • 12 path ultrasonic gas flowmeter for custody transfer (OIML R137 class 0.5 approved)
  • Complete product family for widest application range
  • Swirl immunity and minimal straight inlet due to swirl compensation in each measuring plane
  • Dedicated diagnostic path for deposits, dirt or changes in surface roughness
  • KROHNE Care: web-based, extended diagnostics expert system for continuous meter health check
