It may be used in single-phase stream of gas or fluids. Truth for gas period of flight yards is +/-1.0% of range using factory fabricated pipe.
Only time-of-flight KP-LOK metering valve (transit time) meters shall be utilized. Multi-path time-of-flight meters should be considered if high accuracy is required or in case straight length requirements can’t be met for a single path time-of-flight meter. Multi-path should likewise be utilised in low Reynolds number (< 5000) flow conditions. Ultrasonic meters are ideal to big lines, with large flow speed turn down.
Such a meter is well suited to flare measurement. This type of meter might be used on off gas from separators requiring a huge flow rate ignore, given there is adequate distance for the required upstream and downstream lengths.
This type of flow meter won’t be useful for custody transfer overseas until various issues about inspection and testing are all resolved using the regulating authorities.
Ultrasonic meters in significant gas service will have retraction mechanisms for probe removal under great pressure.
Clamp-on ultrasonic meters might just be employed for liquid cessation. Clamp-on meters are suitable for usage in many piping substances.
Ultrasonic meters could be used in blood flow.
Ultrasonic meters KP-LOK have quite big Turndown ratios up to 100 to 1 in some software, but
