Round-the-clock operational safety and plant availability are important in all process industries, but none more so than in the chemical industry.
Our new range of two-wire flowmeters has been designed with the chemical industry in mind to offer accurate, reliable and safe flow measurement in the toughest of applications. Whether you want to measure mass or volume of a liquid, steam or gas, we have a true two-wire flowmeter for the job.
Operators in the chemical industry have to balance a number of, sometimes conflicting, requirements including plant performance, flexibility and cost-effectiveness. They are also confronted with a growing diversity of measuring tasks and device types. This complexity can only be managed by standardisation of field instrumentation. Two-wire technology is well-established in the chemical industry and has revolutionised many of the available measurement technologies. Now Endress+Hauser’s range of Proline 200 flowmeters offers the efficiency of two wires for all flow measurement tasks, whether your application demands Coriolis, vortex or electromagnetic technology. And, as the hardware and software was developed completely in accordance with SIL (IEC 61508), the range is ideally suited
for use in safety systems.
Two-wire Coriolis meter
Promass 200 is the world’s first Coriolis flowmeter with genuine, industry-compliant two-wire technology (4–20mA). It enables the device to be seamlessly integrated into existing infrastructures and control systems due to a familiar and uniform installation procedure. It also offers high operational safety in hazardous areas thanks to an intrinsically safe design (Ex ia) and costs less than traditional flowmeters to install and wire.
Efficiency through uniformity
Proline 200 flowmeters are based on a uniform concept that significantly reduces complexity for the end user. The new concept standardises operation, menu structures, function designations, software, interfaces, data management, system integration, display of errors, documentation and even product structure. These innovations create long-term benefits over the entire lifecycle of a plant.
Industry standards
Safety requirements and cost pressures compel many branches of industry to meet regulations, standards or recommendations. All Proline 200 flowmeters have been developed in accordance with SIL and NAMUR recommendations (NE 131 and NE 132) to ensure compliance with such regulations and standards. They also meet the requirements for interference immunity, data retention in the event of a power failure, signal level, software, pressure equipment directive, self-monitoring, error display and much more.
A complete range of 2-wire flowmeters
- Promass 200 Coriolis flowmeter (8 to 80mm) for mass, volume, density and temperature measurements of liquids and gases.
- Promag 200 electromagnetic flowmeter (2 to 200mm) for volume flow of conductive liquids.
- Prowirl 200 vortex flowmeter (15 to 300mm) for liquids, gases and steam.
Heartbeat Technology
Our new generation of Proline flowmeters is fitted with Heartbeat Technology to provide continuous or on-demand diagnostics, monitoring and verification. This ensures your flowmeter is functioning correctly, independent of process and ambient conditions. This unparalleled self-monitoring capability offers complete flexibility to plan proof-testing and other maintenance with minimal effort and exposure of personnel.
Diagnostics allow for a rapid response to a device reaching a critical condition. A warning will be given, in accordance with NAMUR recommendation NE 107, and displayed by the device as a diagnostic event. The user will also be given direct instructions on the correct action to take. Heartbeat Technology also includes comprehensive condition monitoring, making it possible to display temporary, process-specific faults that neither calibration nor verification can detect.
Verification can be used to take and store a snapshot of the device status, in order to demonstrate that the flowmeter meets specific technical requirements defined by the manufacturer or user. During verification, the current conditions of the secondary parameters are compared with their reference values, thereby determining the device status. A traceable and redundant reference, contained in the verification system of the device, is used to ensure the reliability of the results. Verification results produce a report, which includes a qualitative assessment of the checked parameters as well as noting whether the device passed or failed. The report can be used to comply with ISO 9001 or, in safety-related applications, as documentation of the proof test. Up to eight verification reports are stored in the device.
Sensors proven in use
Endress+Hauser’s flowmeters are proven in use in real-world applications in the chemical industry. In our 60 year history we have successfully installed over three million Coriolis, electromagnetic and vortex flowmeters. And, as all Endress+Hauser flow measuring devices are tested on accredited and traceable calibration facilities (to ISO 17025), you’re guaranteed the greatest measuring accuracy and repeatability, even in long-term operation.
