2-wire Coriolis flow meters

Sept. 3, 2008
Here’s something new in Coriolis meters from Emerson Process Management–MicroMotion.

The first two-wire Micro Motion Coriolis meter expands the value of Coriolis to the wide range of applications that require loop-powered flow devices. The new Coriolis meters are designed for upgrading older loop-powered technologies to Elite Coriolis meters without adding more power or installing new cabling.

The new meter delivers +0.10% liquid flow and +0.0005 g/cm3 liquid density accuracy in continuous process and mass balance applications. It has no moving parts and requires no maintenance. The two-wire Micro Motion 2200S transmitter can be used with a range of Micro Motion Elite Coriolis sensor sizes and materials of construction to deliver measurement performance for continuous process applications. Suitable for integral or extended mount, the loop powered design makes for seamless integration into existing control systems and is ideal for long wiring runs and applications in hazardous areas.

Equipped with MVD digital processing technology, the Micro Motion 2200S transmitter delivers multivariable and diagnostic information via HART communications. Front-end digital processing dramatically reduces signal noise and gives a faster response time compared to analog devices.
