- Scope
- This part of GB/T 34041 specifies the requirements and recommendations for gas ultrasonic flowmeters (hereinafter referred to as flowmeters) that use the transit time of acoustic signals to measure the flow of a single homogeneous gas in a closed pipeline. The structure, flow measurement performance, calibration, and output characteristics requirements and installation conditions of gas ultrasonic flowmeters with two accuracy levels for split-transmission measurement. This section applies to transit-time gas ultrasonic flowmeters for custody transfer metering and distribution metering, including gas ultrasonic flowmeters with equal diameter, reduced diameter high pressure, low pressure or any combination of these types. This standard does not limit the maximum or minimum value of the flowmeter. This section can be applied to the measurement of various types of gas, including air natural gas, ethane, etc.
