Q.Sonic Ultrasonic Gas Flow Meters for custody transfer measurement Applications Media: Natural gas Industry: Gas exploration, gas transmission, gas distribution

Brief information

Main features

Ultrasonic Gas Flow Meter applications have expanded considerably since their introduction over two decades ago. Tougher applications demand technically advanced solutions and Elster-Instromet continues to meet the challenge. The 4th generation ultrasonic meters produced by Elster-Instromet today are the most sophisticated on the market and contain many advancements including those listed aside. The Q.Sonic line of ultrasonic flow meters are the only ones featuring extended diagnostics with the possibility of detecting fouling and ultrasonic flow pattern recognition with dynamic k-factor calculation. Fit for purpose with integrity in measurement: In practice, there are no simple solutions and a “one size fits all” solution cannot be optimal. Thus Elster-Instromet developed a range of Ultrasonic Gas Flow Meters, each model designed to best meet the individual operational demand.

No moving parts No pressure drop Large turn down ratio Bi-directional ISO CD17089 compliant AGA-9 compliant Highest noise immunity Flow profile detection Highest repeatability CMB signal processing

Q.Sonic-3 - Meeting industry standards: With more than 1000 3-path meters in operation worldwide, the Q.Sonic-3 is the industry standard for custody transfer! The Q.Sonic-3 complies with AGA Report 9 and ISO standard CD17089. Q.Sonic-4 - Exceeding industry standards: In addition to the 2 double reflection paths of the Q.Sonic-3 the Q.Sonic-4 has 2 single reflection paths crossing each other at an angle of 90º. This makes the meter less sensitive to asymmetric flow distortions and results in a 10D straight upstream requirement. The meter is designed for short upstream lengths which are most common with offshore applications and measurement and regulation stations. Q.Sonic-5 - The highest standard: The Q.Sonic-5 has the highest level of flow profile recognition in the industry and has long been recognized as the most accurate and flexible ultrasonic meter available. Due to the unique path pattern it gives the most reliable diagnostic data to maintain lowest uncertainty.
