The French mathematician Gaspard-Gustave Coriolis (1792 – 1843) discovered, explained and quantified a force acting perpendicular to the axis of rotation of particles, which is dependent on the mass and angular velocity of these particles.
It was over a hundred years later that his discovery led to the first Coriolis flowmeters. The Coriolis principle enables the direct measurement of mass. Coriolis mass flowmeters are multivariable and can simultaneously measure mass flow, density, temperature, volume and concentration with a very high accuracy. In the last decade, Coriolis flowmeters have changed from general purpose to supporting customers’ needs in specific applications. While the technological complexity has increased, the demand for simple operation and handling is also a growing requirement. Yokogawa has met these needs with Rotamass Total Insight, which has six dedicated product lines with two specialised transmitters, allowing the highest flexibility.
Simplified selection helps customers match requirements
The Rotamass Multi-Tier product line was developed to help meet the challenges of selecting a product to suit specific requirements relating to process, operation, maintenance, cost and safety. Simplified Selection, a founding principle for the Rotamass product line, meets customer requirements for each specific industry and application. Six different sensor lines can be combined with either of the two transmitters to provide tailor-made solutions with the highest flexibility. The product selection and configuration tools support flexible options for customised applications that are easy to select and operate.
To achieve full operational performance, a multi-variable device like a Coriolis flowmeter is essential, but this typically requires extensive setup to maximise results. The Rotamass Expert Guide has a simple and user-friendly configuration concept. The intuitive menu structure, combined with a large, high resolution dot matrix display, makes configuration easy and clear. A setup wizard guides the user through the configuration of all important settings and functions. Three different configuration sets can be stored and recalled at any time. Customer pre-defined views provide an overview of all important values within seconds.
Advanced diagnostics and configuration
Rotamass includes the Process Guard to manage advanced diagnostic capabilities. Nearly 200 different events can be dedicated and classified according to NE 107 by the user. Events can also trigger data-logging of the most important process and device variables. Sustainable and safe operation often requires continuous monitoring of in-line meters. The Maintenance Manager not only continually observes the key sensing elements, but also allows a total health check during operation. Thus interruption of processes can be significantly minimised. With the support of the FieldMate instrument maintenance and configuration tool, a full report including all test results can be provided.
FieldMate is fully aligned with the Rotamass Total Insight philosophy. FieldMate 3.0 is a PC or tablet-based configuration tool that performs numerous tasks, including initial setup, daily maintenance, reporting, troubleshooting and configuration backup for device replacement. It is independent of communication protocols and device vendors, incorporates the open FDT/DTM standard and is compliant with DTMs per the FDT 1.2/2 standard. FieldMate instantaneously supports built-in DTM interpretation of existing Device Description (DD) for other vendor’s devices that do not have DTMs available.
The challenge for flow measurement is to integrate the application, environment and device. Problems often appear when a service engineer is not immediately available. The root cause is typically a complex combination of factors and requires extensive process analysis. The Rotamass Data Mobility concept enables user-defined, event-driven or periodical data logging of all important processes and device values before, during and after an event occurs. The data file, recorded on a microSD card in the transmitter, can be sent from anywhere in the world to the Yokogawa service centre for analysis. Adjustments can then be returned and uploaded to the device.
The lifecycle of an industrial product varies with market demands. As a consequence, flexible production units are needed. Changeover from one product to another has to be realised within a short time to maintain high operational availability of the plant. Rotamass Advanced Flexibility allows the user to add functionality to a device at any time, even after installation, anywhere in the world. Feature on Demand (FOD) allows the user to upgrade the device as needed. The modular I/O concept provides the widest variants of inputs and outputs, as well as bus communication. The universal power supply and worldwide approval make Rotamass ready for action anytime, anywhere.
