The Endress+Hauser FLOWSIC500 ultrasonic flowmeter stands as a benchmark for extremely accurate natural gas distribution measurement. Engineered for precision and reliability, it excels in demanding applications while offering robust features. Notably, it is overload-proof, ensuring continuous and accurate readings even under fluctuating conditions. An intelligent diagnostics system constantly monitors its performance, guaranteeing operational integrity. Its seamless integration into existing measuring stations is a significant advantage, reducing installation complexities. Operating either self-sufficiently with internal energy or within a failsafe network with battery backup, the FLOWSIC500 ensures uninterrupted service. This device adheres to all pertinent international standards and directives, providing the security of a continuous and blockage-free gas supply, crucial for maintaining critical infrastructure and commercial operations.

Measuring Principle: Ultrasonic Time-of-Flight

The heart of the FLOWSIC500’s exceptional accuracy lies in its sophisticated ultrasonic transit time difference measurement principle. This non-invasive technology operates by emitting ultrasonic pulses both upstream and downstream within the gas flow. By meticulously measuring the minute time difference these pulses take to travel across the pipe, the device precisely calculates the gas velocity. This inherent robustness of the ultrasonic principle allows for highly reliable and stable measurements, largely unaffected by changes in gas composition or flow profile. Unlike traditional mechanical meters, the FLOWSIC500 eliminates moving parts, significantly reducing wear, pressure drop, and maintenance requirements, ensuring long-term measurement integrity and operational efficiency in critical natural gas distribution networks.

Device Properties: Robust, Diagnostic, Adaptable System

The FLOWSIC500 is engineered with a suite of device properties that guarantee its superior performance and adaptability in diverse natural gas distribution environments. Its fundamental design, lacking moving parts, contributes to its ruggedness and reliability, minimizing mechanical wear and tear. A key feature is the permanent operational check provided by its intelligent diagnostics system, ensuring continuous monitoring and proactive issue detection. The exchangeable cartridge design simplifies maintenance and recalibration processes, significantly reducing downtime. Furthermore, the FLOWSIC500 does not require a straight inlet/outlet zone, making installation flexible and reducing space requirements. It is inherently overload-proof, capable of handling extreme flow fluctuations without damage. Optional integrated flow conversion and data registration functionalities enhance its utility, while battery or intrinsically safe power supply options provide versatile energy solutions, critical for remote or hazardous locations.

Benefits: Cost Savings, High Safety, Easy Maintenance

The Endress+Hauser FLOWSIC500 delivers substantial benefits that translate into significant operational advantages and cost savings for gas suppliers and industrial users. It ensures the highest measurement certainty and safety, guaranteeing a continuous and reliable gas supply, which is paramount for critical infrastructure. The integrated flow conversion feature directly reduces installation costs by eliminating the need for separate converters. Its simple installation process, coupled with compatibility with conventional technologies like turbine and rotary displacement meters, makes upgrades and replacements straightforward. Minimal operating costs are a key advantage, as the FLOWSIC500 is nearly maintenance-free due to its lack of moving parts. Simplified recalibration through an easy cartridge exchange process further reduces operational expenditures. The device performs reliably even under dynamic load changes, ensuring consistent accuracy, and its self-sufficient operation offers unparalleled flexibility in deployment, especially in remote or challenging locations.

Specific Applications: Gas Distribution Networks Essential

The FLOWSIC500 is precisely designed for critical roles within natural gas distribution networks, ensuring accurate and reliable measurements at various points. Its primary field of application is in natural gas distribution in transfer and measuring stations for municipal and regional gas suppliers. Here, it provides the precise data required for billing, network balancing, and loss detection. Beyond large-scale distribution, the FLOWSIC500 is ideally suited for measuring stations in industrial and commercial applications. This includes large factories, power plants, and commercial complexes where accurate gas consumption monitoring is essential for operational efficiency and cost management. Its ability to operate in a self-sufficient energy configuration or with battery backup makes it perfect for remote or off-grid locations within these distribution and industrial settings. The FLOWSIC500’s robust design and high accuracy ensure that whether it’s a city gate station or a commercial boiler room, reliable gas measurement is consistently delivered.

Measured Variables: Comprehensive Gas Data Acquisition

The FLOWSIC500 is adept at providing a comprehensive suite of measured variables crucial for effective natural gas management and billing. It accurately determines volume a.c. (actual conditions) and volumetric flow a.c. (actual conditions), delivering real-time data on the current state of gas flow. Furthermore, it measures gas velocity, offering deeper insights into flow dynamics. For applications requiring standardized reporting and billing, the FLOWSIC500 can provide volume s.c. (standard conditions) and volume flow under s.c. (standard conditions) as an additional function with its integrated volume correction capabilities. The device is specifically calibrated for measuring natural gas (dry, odorized), ensuring optimal performance for typical pipeline gas compositions. This extensive range of measured variables ensures that operators have all the necessary data for efficient network management, accurate commercial transactions, and compliance with regulatory requirements.

Accuracy and Repeatability: Setting Industry Benchmarks

The FLOWSIC500 sets high industry benchmarks for accuracy and repeatability, crucial for financial equity in gas distribution. Its repeatability is exceptionally low, typically ≤ 0.1 %, ensuring highly consistent measurements over time. The device offers impressive accuracy across its operational range: from Qmin up to 0.1 Qmax, accuracy is ≤ ± 1 %, and from 0.1 Qmax up to Qmax, it improves to ≤ ± 0.5 %. For applications adhering to accuracy class 1, the maximum allowed error limits are ≤ ± 2 % for Qmin up to 0.1 Qmax, and ≤ ± 1 % for 0.1 Qmax up to Qmax. Following high-pressure flow calibration, the accuracy is even tighter, achieving ±0.2 % at test pressure, and otherwise ±0.5 %. These rigorous specifications underscore the FLOWSIC500’s capability to deliver precise and reliable data for billing, operational control, and regulatory compliance, making it a trusted instrument in the gas industry.
