The Japanese flowmeters manufacturer Aichi Tokei Denki makes available two series of ultrasonic flowmeters for fuel gas, ATZTA UX and UZ. These flowmeters measure accurately fuel gas consumption thanks to measurable low flow of burners and boilers with a large turndown ratio. ATZTA UX and UZ series may be used in other various applications, such as fuel efficiency management and air-fuel ratio control.
Wide rangeability 1:50 from the measurement starting flow-rate to the maximum flow-rate enables the measurement at the time of the standby operation. For elbow and flexible pipe connection, the original structure of flow pass achieved the installation without straight pipe section, which is space saving. The original structure also removes the pipe noise which influences ultrasonic measurement.
