Critical Technical Advantages
-
Optimized for High-Pressure Low Flow: While many meters struggle at high pressures with low velocities, the FLOWSIC550 is tuned to maintain high measurement certainty in these specific conditions. This ensures accurate billing even when demand is at its minimum in a high-pressure grid.
-
Blockage-Free Security: The full-bore ultrasonic design contains no moving parts that could wear out or jam. This ensures that even if the meter encounters pipeline debris or extreme pressure surges, the gas supply to the downstream customer remains continuous and uninterrupted.
-
Integrated Volume Correction: To reduce installation complexity and costs, the FLOWSIC550 can include an integrated volume corrector. This allows the device to perform PTZ (Pressure, Temperature, Compressibility) calculations internally, providing standardized volume data directly to the SCADA system.
-
Maintenance-Free Reliability: The lack of moving parts eliminates the need for lubrication or mechanical repair. The device’s intelligent diagnostics system provides permanent operational self-monitoring, shifting maintenance to a predictive “as-needed” model.
-
Modern Connectivity with BLE: The inclusion of Bluetooth Low Energy (BLE) allows technicians to perform commissioning, parameterization, and data reading wirelessly via the FLOWgate™ App. This is particularly valuable for meters installed in confined or hazardous areas where physical access is difficult.
-
Robustness Under Fluctuating Loads: Unlike mechanical turbine meters that can suffer from over-spin or mechanical stress during rapid on/off cycles, the ultrasonic sensors react instantaneously to flow changes, providing accurate measurement regardless of load dynamics.

Primary Applications
-
Town Border & City Gate Stations: Serving as the primary fiscal measurement point for municipal high-pressure gas injection.
-
High-Pressure Industrial Supply: Accurate billing for large industrial consumers connected directly to high-pressure transmission lines.
-
Gas Storage Systems: Monitoring low-flow injection or withdrawal rates in high-pressure storage facilities.
-
Turbine Meter Replacement: Ideal for retrofitting existing stations due to compact dimensions and standardized face-to-face lengths.
-
On/Off Industrial Processes: Measuring gas flow for boilers or furnaces with high-frequency cycling that would damage traditional mechanical meters.
