A RANGE of ultrasonic flow meters produced by Emerson Process management have faster flow sampling rates to reduce measurement uncertainty and improve uptime, the company has announced.

The Daniel range incorporates the JuniorSonic one-path (3411) or two-path (3412), and SeniorSonic four-path (3414) gas ultrasonic meters, which Emerson says is ideal for a number of f low measurement applications.

The Daniel four-path (3814) liquid ultrasonic meter expands on the functionality and performance of its predecessor, the 3804 liquid ultrasonic meter, to offer improved reliability for custody transfer applications.

Emerson said the electronics platform of the meters increased the data set used to calculate average velocity, allowing rapid recognition of changing flow dynamics.

Users will have access to high-volume data capture as well as detailed flow parameters, including pressure, temperature, and gas composition, allowing the meter to act as a redundant flow computer.

The devices also offer improved calculations for auditing or invoice resolution through their rapid delivery of key data from the meter’s audit trail, which complies with American Petroleum Institute Standard 21.1.

The meters’ electronics also feature a compact circuit board for increased reliability and maintainability, simplifying field removal and reinstallation.

The electronics retrofit Daniel legacy ultrasonic meters and are expandable, as well as supporting remote access and true 100BaseT Fast Ethernet connectivity to facilitate enterprise-wide communication and integration.

Emerson’s Daniel measurement and control business vice president of engineering Peter Syrnyk said providing reliable and accurate measurements were critical to the businesses of his customers.

“We remain focused on designing products that serve these important market needs and are continually improving the performance of ultrasonic flow measurement technology to provide excellent long-term measurement accuracy.”

To further improve reliability and uptime, each Daniel gas ultrasonic meter is supplied with new, rugged T-20 Series transducers that are engineered for wet, rich or dirty gas applications.

The transducers facilitate troubleshooting by enabling operators to quickly detect and isolate problems, preventing unnecessary depressurization of the meter.

The new Daniel gas and liquid ultrasonic meters are also equipped with an updated version of MeterLink (v1.10), a configuration and diagnostic software that uses an intuitive interface to improve overall functionality and ease of use.

MeterLink displays abnormal flow profiles, upstream blockage, deposit build-up within the meter, and the existence of liquid hydrocarbon in gas—an invaluable benefit for shale gas applications and new pipelines where remains of hydro test water may still exist.

In addition, a guided wizard tool helps configure the meter in the field, decreasing commissioning time and minimising start-up costs and operator error.
