Process measurement devices must often rely on each other to jointly serve the multiplying needs of their users, who aren’t just demanding better performance and useability, but must also improve environmental performance. Meeting these requirements often requires additional points of measurement, which facilitate progress towards digitalization.

To achieve these aims, Emerson presents Micro Motion G-Series Coriolis flow and density meter and Micro Motion 4700 Coriolis transmitter. These two devices can be used together or separately, but either way, they provide the advantages of Coriolis flow measurement in a competitively priced package for many applications that likely wouldn’t consider using them before.

“Users are facing growing demands for greater asset efficiency, but must also meet new environmental, social and governance (ESG) requirements,” says Meghan Edwards, product manager for Micro Motion Coriolis sensors at Emerson. “The answer to those requests is G-Series and its completely reimagined and patented dual-tube sensor design. It puts all the standard Coriolis functions and performance in an ultracompact and lightweight package, which is half the size of similar Coriolis devices, and lighter than other Micro Motion models.”

Edwards adds that Micro Motion G-Series is available in five process line sizes, including ¼ in., ½ in., 1 in., 2 in. and 3 in, all made of 316 stainless-steel.

Not to be outdone, the Micro Motion 4700 Config I/O Coriolis transmitter is the first of Emerson’s Coriolis products to have Bluetooth wireless connectivity, which gives it a 50-foot range between the transmitter and any device running the AMS Device Configurator application. The configurator can quickly locate and identify transmitters, and then users can connect remotely, gather and view internal diagnostics and data, update configurations, and perform other functions—all without touching the transmitter, having to open it in hazardous settings or obtain a hot-work permit.

“Many customers are asking for updated electronics, easier-to-use touchscreens and compliance with global, lead-free initiatives, and these and other features are provided by the 4700 transmitter,” says Brett Sibel, product manager for Micro Motion transmitters and electronics at Emerson.

To help users switch to upgraded transmitters, but avoid the cost of replacing flow sensors, Micro Motion 4700 Coriolis provides a retrofit solution for the Micro Motion 1700 and 2700 field and integral-mount transmitters. Once installed, the new transmitter interfaces with the existing flowmeter, adding new electronics capabilities. Micro Motion 4700 is suitable for installation with integral and remote Micro Motion Elite (CMF and CMFS), F-Series, G-Series, H-Series, R-Series, T-Series and remote HPC-Series Coriolis flowmeters.

Sibel reports that the Micro Motion 4700 transmitter also features:

• Fully backlit local operator interface that’s fully configurable from the display, and controlled with four capacitive touch buttons;

• Multiple configurable, wired I/O channels, such as Channel A with 4-20 mA HART, frequency output and a discrete output, Channel B with 4-20 mA, frequency, discrete output and discrete input, and Channel C with Modbus RS-485;

• USB A port for local connection;

• Smart Meter Verification Basic and Zero Verification software provided standard, and Smart Meter Verification Professional software available as a licensable option for accessing and printing reports;

• Optional Advanced Phase Measurement software available as an option for detecting multiphase conditions when process fluids contain entrained gas;

• Optional, built-in data historian for storing up to 11 days of data at a one-second scan rate, and simultaneously storing up to one year of data at a five-minute scan rate; and

• Corrosion-resistant, aluminum housing rated for Zone 1 installation, as well as a SIL 2 rating as a single device and SIL 3 capability when multiple meters are installed.

“One of the primary benefits of using Coriolis to measure mass flows, instead of traditional, volumetric technologies like magmeters or vortex, is that Coriolis has no moving parts to wear out,” adds Edwards. “And now, G-Series and 4700 Coriolis with their compact size make them more accessible and usable in applications where Coriolis wasn’t available before, such as certain chemical processes, and by OEMs and skid builders with space constraints. Next spring, we’ll also launch hygienic versions of G-Series and 4700 Coriolis for use in food and beverage and life sciences applications.”
