Measurement of fluid flow in closed conduits. Ultrasonic meters for gas - Meters for custody transfer and allocation measurementWhat is ISO 17089 1 Ultrasonic meters for gas about? ISO 17089 1 is a safety standard on ultrasonic meters for gas. It specifies requirements and recommendations for ultrasonic gas flowmeters (USMs), which utilize the transit time of acoustic signals to measure the flow of single phase homogenous gases in closed conduits. ISO 17089 1 applies to transit time ultrasonic gas flowmeters used for custody transfer and allocation metering, such as full bore,
