<p>This part of ISO 17089 specifies requirements and recommendations for ultrasonic gas meters (USMs), which</p>
<p>utilize acoustic signals to measure the flow in the gaseous phase in closed conduits.</p>
<p>This part of ISO 17089 is applicable to transit time USMs and is focused towards industrial flow measurement.</p>
<p>Included are meters comprising meter bodies as well as meters with field-mounted transducers.</p>
<p>There are no limits on the size of the meter. It can be applied to the measurement of almost any type of gas;</p>
<p>such as but not limited to air, hydrocarbon gases, and steam.</p>
<p>This part of ISO 17089 specifies performance, calibration (when required), and output characteristics of USMs</p>
<p>for gas flow measurement and deals with installation conditions.</p>
<p>NOTE It is possible that national or other regulations apply which can be more stringent than those in this part of ISO 17089.</p>
