Emerson Process Management has introduced the new Daniel™ 3818 Liquid Ultrasonic Flow Meter for liquefied natural gas (LNG) applications.

Specifically designed for reducing flow measurement uncertainty throughout the LNG value chain, the new flow meter perhaps exemplifies the growing significance of the LNG business for the industrial gas and equipment industry.

The flow meter is ideal for many marine and offshore applications, including custody transfer, fiscal metering, line balancing, check metering, allocation measurement and tanker loading and unloading.

Measuring LNG volume dynamically using the Daniel 3818 Ultrasonic Meter delivers higher accuracy than static measurement methods and can result in real savings. The 3818 provides a factory-proven linearity within ± 0.15% and a meter factor uncertainty of ± 0.027% due to its sophisticated multi-plane British Gas design, fast signal processing, and advanced transducer technology.

Improvements in measurement uncertainty equate to a reduction in risk of the financial transaction. Additional metering points on rundown lines can also improve process control.

Spot contracts

Industry forecasts anticipate increasing amounts of LNG will be traded in short-term (spot) contracts. This implies dynamic measurement of delivered product will be required, as is currently the case for custody transfer of oil shipments.

In addition, LNG facilities are using shared or commingled storage tanks which require dynamic measurement to quantify and allocate ownership among multiple parties.

With a completely redundant 4-path, multi-plane configuration that is the equivalent of two 4-path meters in a single body, the Daniel 3818 Ultrasonic Meter utilises two independent transmitters – one for each set of four chordal paths.

“We continue to develop and perfect a wide range of ultrasonic flow meters for liquid and gas measurement,” said Peter Syrnyk, Vice-President of Engineering at Emerson Process Management, Daniel. “The introduction of the 3818 Liquid Ultrasonic Meter addresses the industry’s need for custody transfer to be based on more accurate measurements by all stakeholders in the LNG value chain.”
