Application Cases of Custody Transfer Measurement for Natural Gas

Thermal gas mass flow meters are widely used for high-precision natural gas trade metering and gas billing in industrial plants and residential communities. Unlike conventional volumetric flowmeters that require complicated temperature and pressure compensation, our thermal mass flow meters utilize the thermal mass flow principle to directly measure gas mass flow. This ensures precise and consistent readings even under fluctuating gas pressure, temperature, and varying working conditions.

ASY instruments offer an extremely wide turndown ratio. They accurately measure ultra-low gas consumption and capture peak high flow rates, effectively eliminating typical metering defects such as low-flow missing counts and unstable deviations at high flow. With no moving parts or throttling components inside, our anti-clogging structure is perfectly compatible with natural gas carrying trace impurities. These devices operate reliably for long periods under complicated field conditions, providing a near maintenance-free performance that is suitable for demanding industrial energy monitoring.

ASY gas mass flow meters support real-time mass flow totalization and automatic data logging. Remote signal transmission is available via 4-20mA analog output and RS485 Modbus communication, enabling remote meter reading, automatic gas consumption calculation, and intelligent data management. These meters supply authentic, reliable, and traceable measurement data for natural gas trade settlement, customer gas charging, and pipeline gas balance control. As a reliable and cost-effective solution for natural gas custody transfer metering, ASY instruments are standard equipment for industrial and commercial applications.
