Emerson has introduced the Micro Motion™ G Series Coriolis Mass flow and densimeter, the most compact two-tube Coriolis mass flowmeter on the market today. The high-precision G Series Coriolis flow and density meters offer the same quality and reliability as standard designs, but in a smaller and lighter form factor. Compared to conventional volumetric flow meters, the new flow meter can directly measure mass flow, independent of process temperature/pressure changes and advanced process and operating condition diagnostics.

Emerson also introduced the High Precision 4700 Coriolis transmitter, adding the ability to work directly with the high precision series Coriolis flow meter. This transmitter can be retrofitted to most existing high-precision sensors and can be ordered with all new flow meters, including the new high-precision G series. The combination of these two new products provides an ideal solution for applications in the chemical and other industries.

High precision G series flow and density meters

For chemical plants that need to improve safety and reduce energy consumption and emissions, high-precision G-Series flowmeters are a good choice. This series of flowmeters has Pressure Equipment Directive (PED) certification, safety integrity levels SIL 2 and SIL 3, and complies with NAMUR NE 132 guidelines. The sanitary flowmeter, which will be introduced in the first half of 2024, can be used in food and beverage, life sciences, and other applications requiring 3-A or European Sanitary Engineering and Design Organization (EHEDG) certification.

Although Coriolis flowmeters do not require upstream or downstream straight pipes like many other flow measurement technologies, the larger size of some models limits their use in tight Spaces. Emerson’s new flow meter solves this problem with a 1-inch diameter and less than 12-inch face spacing. The new product is not only compact in appearance, but also greatly reduced in weight, which improves the transportation, installation and safety of the product.

Communication and power supply options are also flexible, reducing installation costs and complexity. It can be connected to the host system via discrete signals and 4-20mA HART® signals, or via digital connections including Wi-Fi, Bluetooth® technology and Power over Ethernet (PoE) solutions. PoE schemes include Ethernet /IP, Modbus TCP or PROFINET. Each of these digital connections supports two-way communication of a variety of data, including process variables, diagnostics, status, configuration, and calibration data. This data can be used to perform proactive maintenance and enable digital transformation.

The product is available in six pipe sizes ranging from ¼ “to 3”; In addition, product selection is only possible with a very streamlined configuration. Direct laser-etched labels are durable even under extremely harsh conditions, eliminating the need for adhesive labels and spot-welded labels. Easily accessible via QR codes, the MyEmerson Digital Specification tool provides a quick and easy solution for storing and accessing information about each flowmeter.

High precision 4700 configuration I/O Coriolis transmitter

End-users have used high-precision Coriolis flowmeters in a wide range of industries, including chemical, food and beverage, life sciences, oil and gas, and petrochemical industries. The main focus for end users is to switch to upgraded transmitters with more functionality and benefits, while saving money on replacing existing flow meter installations that have often provided decades of peace of mind service.

However, the High Precision 4700 Coriolis transmitter solves this problem by providing a retrofit adapter solution to replace older transmitters in existing flow meters. After installation, the transmitter will automatically connect to the existing flow meter and provide new functions, as if a new flow meter had been installed. The transmitter is compatible with all high-precision ELITE® (CMF and CMFS), F Series, H Series, R Series, T Series, HPC Series and the new G Series Coriolis flow meters.

This transmitter adds a number of new features, including a Bluetooth connection scheme. The solution provides wireless communication when the transmitter is separated from the Emerson AMS device configurator by up to 50 feet (15 meters). Wireless connectivity via Bluetooth technology allows users to configure flowmeters and access smart instrument self-calibration diagnostics and process information.

With the AMS device Configurator application, users can quickly locate and identify transmitters and then perform tasks related to configuration, device status, and diagnostics. Since the transmitter no longer needs to be opened for maintenance, it does not need to be exposed to the environment, thus improving reliability.

The transmitter has three configurable wired I/O channels to provide connection cables, including 4-20mA HART, frequency output, switching quantity output and input, and Modbus RS-485. The High Precision 4700 provides the ideal solution for upgrading existing high precision Coriolis flowmeters and can be used as a new device to provide advanced features.

The process industry can rely on Emerson’s reliable equipment and proven expertise to use both products, individually or in combination, to increase operational efficiency and improve equipment maintenance programs.
