The Function Of Ultrasonic Meter

Ultrasonic Meters

It may be used in single-phase flow of liquids or gas. Accuracy for gas time of flight meters is +/-1.0% of range with factory fabricated pipe spool. Accuracy for clamp-on liquid time of flight meters is +/- 2% to 5% of range.

Clamp Meter

Only time-of-flight (transit time) meters shall be used. Multi-path time-of-flight meters should be thought about if high accuracy is required or if right length requirements cannot be met for a single path time-of-flight meter. Multi-path should also be used in low Reynolds whole (< 5000) flow conditions. Ultrasonic meters are well mighty for large lines, with large flow rate turn down.

This type of meter is well mighty for flare measurement. This type of meter may be used on off gas from separators requiring a large flow rate turn down, in case,granted there is enough space for the required upstream and downstream lengths.

This type of flow meter will not be used for custody exchange offshore until assorted issues about inspection and testing are resolved with the governing authorities.

Ultrasonic meters in necessary gas aid shall have retraction mechanisms for probe discharge under pressure.

Clamp-on ultrasonic meters may only be used for liquid metering. Clamp-on meters are suitable for use on most piping materials.

Ultrasonic meters may be used in bi-directional flow.

Ultrasonic meters have very large turn down ratios, of up to 100 to 1 in some applications, but

normally in the 40:1 range.

General factory guidelines for ultrasonic meters are as follows:

• May be installed whether in the vertical or horizontal. In horizontal runs probes shall be installed in the horizontal (90 degrees or 45 degrees angle) to avoid lowest of pipe debris collection, and or vapor in a liquid line at top of pipe.

• Avoid locations with high noise (noisy operate valves).

• operate valves with low noise trims furnish high frequency noise that may interfere with the estimation and may wish a special silencer in the middle of meter and valve, or a long run of pipe separating the two.

Upstream and downstream requirements vary in the middle of manufacturers. The maker must be consulted on the required right lengths.
