Coriolis meters measure smaller flows
Emerson Process Management is expanding its Micro Motion ELITE Coriolis meter offering for low-flow applications. The new Micro Motion meters are compact in design and available in two sizes, 2mm and 4mm nominal diameter, delivering +/-0.05 per cent liquid flow accuracy, +/-0.35 per cent gas accuracy and +/-0.0005g/cc liquid density accuracy for flow rates of 2kg/h to 330kg/h.
Low flow rate applications often require measurement devices that can deliver high turndown capability with uncompromising measurement performance in real-world conditions. Likewise, these applications often require meters that are drainable and have a compact footprint. The new Micro Motion ELITE Coriolis meters have been precisely engineered with these exact challenges in mind, offering stability and robust performance in a drainable, slim and lightweight package.
These new Micro Motion ELITE meters are less than 50mm wide to fit in tight spaces and weigh just 4kg, thereby eliminating the need for special mounting supports. Full secondary containment is standard. With 316L stainless steel wetted parts, the sensor enclosure is available with polished 316L external surface and rounded corners. Superior cleanability and corrosion resistance make the new meters suitable for both hygienic and off-shore applications. For corrosive and high-pressure applications, the Micro Motion Coriolis meters are also available in nickel alloy construction and are rated to 413bar (6000psi).
Further advantages
Micro Motion ELITE Coriolis meters offer advantages not just from the state-of-the-art sensor design, but also from powerful electronics that ensure fast and noise-free signal processing to deliver an excellent two-phase flow measurement capability and empty-full-empty batching. These meters are available with in situ Micro Motion meter verification technology, which is said to be the only true and complete assessment of meter performance (sensor through electronics) at the touch of a button. The new Micro Motion ELITE Coriolis meters are available with four-wire or two-wire electronics, and with a variety of analogue outputs or digital protocols including Foundation fieldbus, Profibus DP and DeviceNet.
All Micro Motion Coriolis devices reliably measure mass flow, volume flow, density and temperature from a single device and can measure multiple products without the need for recalibration. Designed for batching, dosing, filling, blending and a wide range of process applications, the new Micro Motion ELITE Coriolis meters are suitable for the chemical, oil and gas, food and beverage, life sciences, pharmaceutical and OEM industries. To complete the low flow measurement range, the new Micro Motion meters are complemented by Micro Motion LF-Series Coriolis meters that deliver precise measurement down to 0.06kg/h, which are suitable for research and pilot plants.
