Emerson Process Management has announced its new Daniel 3818 liquid ultrasonic flowmeter for liquefied natural gas applications. Specifically designed for reducing flow measurement uncertainty throughout the LNG value chain, this 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% 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.
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. This ensures complete measurement redundancy and the ability to poll each 4-path meter separately. Acoustic processing is performed by specialised electronics designed to achieve high sampling rates, provide stable ultrasonic signals and optimal low flow response, delivering accurate, stable and reliable measurement.
