Endress+Hauser FLOWSIC550 | High-Pressure Ultrasonic Gas Meter for City Gate Stations

The New Benchmark for High-Pressure Natural Gas Distribution

The FLOWSIC550 is a state-of-the-art ultrasonic compact gas flowmeter specifically engineered for high-pressure networks. It excels where traditional mechanical meters struggle: providing ultimate measurement certainty for low volume flows under high-pressure conditions (up to 100 bar and beyond depending on configuration).

At Hanyu Zhilian, we recommend the FLOWSIC550 for city gate stations and industrial transmission systems where reliability is paramount. Its design contains no moving parts, ensuring a 100% blockage-free gas supply. Furthermore, the integrated Bluetooth Low Energy (BLE) and FLOWgate™ App allow your technical team to perform diagnostics and data retrieval safely from a distance, minimizing exposure to high-pressure zones and harsh weather.

Technical Specifications at a Glance

Strategic Advantages: FLOWSIC550 vs. Conventional Technology

• Mastering Low Flow at High Pressure: While turbine meters lose accuracy as pressure increases and flow drops, the FLOWSIC550 maintains its 0.5% precision, capturing "lost" gas that others miss.

• Smart Monitoring (BLE): Eliminate dangerous ladder climbs or entering hazardous zones. Use the FLOWgate™ app to check meter health and download reports wirelessly.

• Blockage-Free Safety: Unlike rotary meters that can jam and cut off gas supply, the ultrasonic path of the FLOWSIC550 is wide open, ensuring zero risk of mechanical failure blocking the line.

• Lower Total Cost of Ownership (TCO): No bearings to lubricate and no gears to wear out. The self-monitoring i-diagnostics™ notify you only when maintenance is truly required.

• Hanyu Logistics & Support: We provide compliant technical selection and rapid global delivery, ensuring your high-pressure infrastructure project stays on schedule.

Case Study: Smart City Gate Station Optimization

The Challenge: A municipal gas operator at a high-pressure (40-bar) "City Gate" station struggled with inconsistent billing during off-peak hours when flow rates dropped significantly.

The Hanyu Solution: We supplied and provided technical guidance for the FLOWSIC550 integration.

• The Result: The operator successfully captured low-flow data with 0.5% accuracy, significantly reducing unaccounted-for gas (UFG).

• Impact: Technicians now use the BLE app for remote reporting, increasing onsite safety by 80% by reducing time spent in high-pressure enclosures.

Frequently Asked Questions (FAQ)

Q1: Can the FLOWSIC550 be used for billing/custody transfer?
A: Yes. The FLOWSIC550 is designed and certified for high-precision custody transfer, providing the accuracy required for fiscal billing in natural gas distribution and industrial networks.

Q2: How does the Bluetooth (BLE) function comply with hazardous area regulations?
A: The FLOWSIC550 is ATEX/IECEx certified. The Bluetooth interface is intrinsically safe, allowing for wireless communication via an approved mobile device within the specified zones.
