Over the last few years, Emerson’s Micro Motion Coriolis flow meters saw important advances in measuring capabilities. This includes the new release of products such as Emerson’s Micro Motion 1600 Config I/O Coriolis Transmitter. Understanding what the new transmitters offer is the subject of my article in the August issue of Process Instrumentation, Advanced Coriolis Transmitter Capabilities Now Available.
But before we think about the new transmitter options, let’s remind ourselves what’s special about Micro Motion flow meters:
Coriolis meters measure true mass flow, density, and temperature directly. This eliminates any guesswork on unit conversions, and it provides a consistent and reliable measurement, regardless of variable process conditions. Such a measurement is far preferred for applications where high accuracy is paramount, especially when process conditions are subject to significant changes.
So what about the transmitters? What has Micro Motion added?
The latest Coriolis transmitter designs have expanded available options significantly in terms of the housing, inputs and outputs (I/O), and software. Additional I/O as well as scalable advanced software features ,such as a historian, can be added either during the initial order or after installation, allowing users to purchase only the features they need, and to then upgrade if and when required.
Transmitter selection for Micro Motion flow meters is more complex than most other types of instruments thanks to the range of measurements they can provide, including direct mass flow, density, temperature, and device drive gain. Therefore, it’s important to have I/O capable of providing such rich data easily, with options such as:
- Basic 4-20 mA with HART, with an optional second I/O channel
- RS-485 to support Modbus RTU, with an optional second channel
- Ethernet connectivity to support Modbus TCP or EtherNet/IP, also with an optional second channel.
There is also a long list of possible software capabilities that can be added to the transmitter. The article provides more detail on these, and it’s an impressive range of useful options that eliminate or reduce the need to write code in-house.
These new capabilities and configuration options have made Coriolis technology an even stronger measurement alternative for a wider range of applications. When considering an existing or new potential Coriolis meter application, users should investigate the latest Coriolis transmitter options, consulting with their supplier as required.
