Ultrasonic Gas Meters from MWA Technology

Ultrasonic Gas Meters

Ultrasonics is used as the measurement principle. There is no obstacle inside the measurement tube so the pressure loss is zero and the energy loss is zero. The meter has a wide range ability of 1:400 which allows for correct measurement with low flow rates.
Aichi AS-WE ultrasonic gas flow meters 40mm to 200mm.
New Aichi UX range 15mm to 50mm.
Also available are Siargo Thermal Mass gas flowmeters and Esters oscillating gas meters .

The ultrasonic meter USM GT400 from RMG delivers highest accuracy and reliability based on field proven six
path technology. Designed for use in a wide range of gas custody transfer and secondary metering applications, the
GT400 measures directly bulk flow rate, swirls, cross-flow and asymmetry. Its patented live precision adjustment/
echo measurement reduces metering uncertainty.

Typical applications include:
• Fiscal metering
• Low-pressure custody/non-custody (atmospheric) transfer
• Allocation metering
• Check metering
• Gas transportation and distribution
• Underground gas storage (bi-directional)
• Gas-fired power plants
• Gas processing plants
• Refining and petrochemical

The GT400 provides improved overall performance thanks to:
• Rugged, non-intrusive design
• Bi-directional measurement
• Real-time system measurement
• Direct path design
• Six-cross acoustic paths
• Direct “cross flow” measurement
• Dynamic 3-D flow profile modeling
• Extended diagnostic functions
• Precise flow profile identification
• Enhanced swirl and asymmetry measurement
• Best-in-class Exd transducer
• Superior noise suppression
• No moving parts or pressure drop
• Wide turndown ratio (>120:1)
• Low-to-high-pressure operation (0-300 barg, 0-4351 psig)
• Extended flow range (0.15-40 m/s , 0.5-131 ft/s)
• Excellent repeatability and measurement certainty
