Advanced version of software offers diagnostics to deliver real-time intelligence and calibration of Coriolis and magnetic fl ow meters for complete process overview and greater operational certainty
Emerson has launched the latest version of its Smart Meter Verifi cation software for Coriolis and magnetic fl ow meters, providing fl ow meter verifi cation on demand and empowering process engineers, technicians and operators to look beyond the meter and make real-time decisions based on the most advanced meter and process diagnostics in the industry today.
New tools in the Smart Meter Verifi cation software allow users to fi ne tune and adjust their engineering processes to ensure absolute measurement confi dence and top performance in the chemicals, oil and gas and other process industries. In addition to onboard diagnostics, Smart Meter Verifi cation also accelerates implementation of companies’ Industrial Internet of Things (IIoT) strategies with its powerful remote diagnostics, digital intelligence and multiple data points providing users with a complete process overview and greater operational certainty. Operators will have clear and transparent verifi cation audit trails, and advanced visual analysis and reporting software that meets third-party regulatory agency compliance requirements in lieu of meter calibration, inspection or removal. By providing a time-stamped verifi cation report, an increasing number of international standards and third-party agencies, such as ISO, IEC, AGA, API, NMI and others, recognise verifi cation technologies, such as Smart Meter Verifi cation, as a method to confi rm instrument calibration and extend recalibration or proving intervals.
Rather than costly and time-consuming calibrations and laboratory testing, leading to production interruptions, shutdowns and safety concerns, the advanced Smart Meter Verifi cation provides in situ calibration verifi cation on-demand without any impact on process or meter outputs. The new system also provides operators with crucial information on other fl ow issues across the plant as well as algorithms that detect corrosion and erosion in the meter with remedial action able to be instigated immediately. Operators will also enjoy the reduced meter maintenance requirements with vital variables, such as mass fl ow, verifi ed to be within factory accuracy specifi cations. Smart Meter Verifi cation also generates detailed information on all sensors, including serial numbers, condition temperature and calibration information, ensuring a simple path to instrument and process compliance. New process diagnostic capabilities that include a ‘fl ow range‘ diagnostic, which alerts the engineer when fl ow rates are not within the specifi ed range of the meter; instrument diagnostics that can identify if entrained gas is in the process; and immediate alerts to process upsets that may affect measurement performance, such as severe aeration. Emerson is also the fi rst company to integrate a 99 percent confi dence statistical meter damage detection algorithm that enables early detection without false alarms. In addition, the Smart Meter Verifi cation system includes new process diagnostic capabilities that include a ‘fl ow range‘ diagnostic, which alerts the engineer when fl ow rates are not within the specifi ed range of the meter; instrument diagnostics that can identify if entrained gas is in the process; and immediate alerts to process upsets that may affect measurement performance, such as severe aeration. Tube coating diagnostics that offer crucial data points and drive valuable information to the end user, alerting them when the meter is coated by something unexpected from the process line are another asset of this system.
“Whereas traditional diagnostics often provide just an entry point to further, time-consuming analysis, the Smart Meter Verifi cation system generates real-time, decision-making intelligence and fl ow measurement confi dence here and now,” said Taylor Scott, software product specialist, Emerson Automation Solutions. “For plant operators and engineers, this move from reactive to predictive diagnostics means improved knowledge, operational certainty and productivity, and the acceleration of IIoT strategies.”
Emerson’s Smart Meter Verifi cation diagnostics are an easy-to-use, automatic tool for Micro Motion™ Coriolis and Rosemount™ magnetic fl ow meters that monitor the entire fl ow meter’s performance and integrity and are applicable in a wide variety of process industry sectors, such as oil and gas, food and beverage and chemicals.

with I2 C interface for areas at risk of explosion The D-line, from KELLER, boasts a unique combination of highly robust industrial pressure transducers and the popular I2 C interface. This successful series has undergone further development and an intrinsically safe version is now available too. The new D Ei series is approved for gas group II applications and can be used to measure absolute and relative pressures in zone 0.
With its modular structure, the series permits numerous combinations, making it the ideal component for customisations using an I2 C interface. KELLER offer OEM pressure transmitters for fi tting directly into a system’s existing drilled holes: 4 LD Ei...9 LD Ei, OEM pressure transmitters with ultra-fl exible pressure connection for screwing into existing pressure systems:20 D Ei, pressure transmitters with a pressure connection and cable gland: 21 D Ei, 23 D Ei and a level sensor for measuring the contents of a tank up to a maximum fi ll level of 3 m: 26 D Ei
The OEM pressure transmitters are available in various sizes and form the basis for the other models with ultra-fl exible pressure connections or level sensors for measuring the contents of a tank up to 3 m.
The 21 D Ei and 23 D Ei models are pressure transmitters with metal casings and
cable outlets. Each offers a different level of accuracy, dimensions, potential applications and numbers of variants. For example, the slightly cheaper 21 D Ei model has a simple cable gland to relieve strain and is suited to use in dry environments, while the 23 D Ei has a premium-quality cable gland boasting protection level IP 68, allowing it to be used underwater and making it ideally suited to use in fl ooded areas.
Pressure transmitters with an I2C interface are normally only available in plastic or ceramic “consumer” housings, with only the compensatory parameters being stored in a memory. The intrinsically safe OEM transmitters from KELLER, however, have their own built-in DSP(digital signal processing) core, which balances and standardises the output values. The I2C (inter-integrated circuit) interface is designed to connect elements directly on a circuit board. The I2C is a bus system in that it connects multiple transmitters (slaves) to the same communication line. For instance, the intrinsically safe D-line combines a pressure interface for industrial use in tougher environments with an electrical interface for OEM applications.
The D Ei series consumes very little energy and is optimised for battery-powered applications. The total error band is just ± 0,7 %FS over a temperature range of -10…80 °C. The hermetically sealed sensor electronics and the compact stainless-steel housing (optional Hastelloy C-276) are extremely resistant to environmental factors.
With pressure ranges of 1 to 1000 bar and an internal two-chip solution that keeps the pressure sensor separate from the signal processing, the D Ei series is extremely fl exible.

A deep virtual insight into chemical processes
Distillation, ammonia and colour pigment processing, energy generation, storage, waste water treatment – the chemical industry has many facets. The specifi cations for the process measurement technologies used are correspondingly diverse and demanding. Because effi cient, robust production processes place special demands on materials, VEGA measuring instruments are available in many different versions. They are always tailored to the respective application. However, the challenge for users is to fi nd the right instrument for the right task – and to optimally use it.
A new, interactive animation on the VEGA homepage now sheds light on all the possibilities. The virtual visit to a chemical park explains typical as well as special processing methods in a concise and understandable way. And it provides answers to questions like: Which measuring principle is suitable for level measurement in an evaporator, when distilling urea? How do I ensure that the absorber pump in a chemical park’s own power plant works reliably? Or: Which instrument versions are robust enough to reliably measure the level and the point level in an ammonia tank?
The animation provides deep insights into plant areas that are not normally accessible. Showing things that are otherwise invisible, it uses this advantage to the full. In the 3D view, the viewer decides for themselves where they want to look. The application ‘help function’ also provides the basis for further steps – on the direct path towards process optimisation. A visit to the virtual plant opens up new perspectives and is also a lot of fun, as the visitor fl ies through the plant as if on wings! Online only:- Experience the tour now at
